237-43-14190 HOSE KOMATSU

The 237-43-14190 HOSE KOMATSU is a short fluid-line hose assembly used on Komatsu motor graders. Public parts sources list the same item under both number formats, 237-43-14190 and 2374314190, and official Komatsu Australia parts listings identify it as a hose in the hydraulic-hose category. Multiple grader parts-catalog sources also place it specifically in brake piping diagrams and describe it as a 300 mm hose, which gives a much clearer picture of its working role on the machine.

From the uploaded images, the 237-43-14190 HOSE KOMATSU appears as a straight, compact hose with metal threaded ends, lock nuts, and a reinforced outer cover. Visually, it looks like a small but important connection piece designed to bridge two fixed metal line points while still tolerating vibration, slight movement, and installation alignment. That matters in grader service, because even a short hose in a brake or hydraulic circuit has to do more than simply carry fluid. It also has to survive constant machine vibration, dust exposure, temperature change, and repeated load cycles.

What the 237-43-14190 HOSE KOMATSU Is

The 237-43-14190 HOSE KOMATSU is not a long main hydraulic line or a large molded radiator hose. Public catalog references consistently describe it simply as HOSE, and the more detailed grader application pages identify it as HOSE, 300MM within brake-piping layouts. In other words, this is a short service hose used in a routed fluid system where compact size, correct end fittings, and exact installed length are essential.

Official Komatsu Australia online parts data classifies 237-43-14190 in the Hydraulic Hose category, while the grader catalog sources place it in brake piping groups. The most reasonable reading of those sources together is that 2374314190 is a Komatsu fluid-transfer hose built to Komatsu hose standards and used in grader brake-piping applications. That interpretation also matches the uploaded images, which show a short, straight, threaded hose assembly rather than a molded coolant or air-intake part.

Why This Hose Matters on a Grader

A machine can have many large, visible parts that get all the attention, but graders also depend on smaller connection components that keep the system stable under working conditions. The 237-43-14190 HOSE KOMATSU belongs to that category. It is the kind of part that can look simple on a bench yet become absolutely critical once the machine is working across uneven ground, under braking load, or during long operating hours.

When a short hose like the 237-43-14190 HOSE KOMATSU is in good condition, it quietly does its job. Fluid moves correctly, the line stays sealed, and the surrounding rigid tubes do not have to absorb every vibration pulse directly. When that same hose becomes cracked, swollen, hardened, damaged at the crimp zone, or mismatched in length, the results can spread outward into leakage, pressure loss, contamination risk, and more difficult maintenance on nearby parts. That is why experienced buyers do not dismiss short hose assemblies as minor items.

Function of the 237-43-14190 HOSE KOMATSU in Brake Piping

Connection between rigid lines

Catalog evidence places the 237-43-14190 HOSE KOMATSU in brake-piping assemblies on many GD-series graders. In practical service terms, that usually means the hose works as a short flexible connector between more rigid line sections or attached fittings in the brake circuit. This kind of component helps maintain sealed fluid routing where a completely rigid connection could be less forgiving during installation or under vibration.

Resistance to vibration and movement

A grader works across rough surfaces, crowned roads, site haul paths, and changing grades. That environment constantly introduces vibration into the chassis, axle area, and attached fluid lines. The 237-43-14190 HOSE KOMATSU likely serves the important job of absorbing a limited amount of this movement while maintaining line continuity. The short overall length shown in the public catalogs and the visible threaded-end construction in your images both support that use case.

Accurate fit in a confined space

The repeated 300 mm listing is not a trivial detail. On compact routed systems, hose length affects installation path, bend radius, clearances, and fitting orientation. A hose that is too short may preload the ends or pull against the line. A hose that is too long may rub, twist, or sit incorrectly. The 2374314190 hose is therefore not just any short hose; it is a specific Komatsu-dimensioned hose assembly intended to sit correctly within a known grader piping layout.

Visible Construction Features in the Uploaded Images

Straight hose body

The uploaded images show the 237-43-14190 HOSE KOMATSU as a straight, slim hose rather than a curved or molded one. This shape is consistent with an installation where the machine already provides the routing geometry and the hose only needs to create a short flexible bridge between two connection points.

Metal threaded ends

Both ends appear to use male threaded fittings with lock nuts. That is important because it suggests the 237-43-14190 HOSE KOMATSU is intended for secure installation into established line hardware, not a clamp-on low-pressure rubber connection. In field service, correct thread compatibility is one of the first things a buyer must confirm when replacing this kind of part.

Reinforced outer cover

The hose body looks reinforced and purpose-built for machine service. Even without destructive testing, the appearance suggests a compact, pressure-capable hose assembly made for equipment conditions rather than general workshop tubing. That visual profile fits what the official Komatsu listing and grader catalog sources imply: a defined fluid-system hose made for a specific machine application.

Komatsu Model Applications for 2374314190

Public Komatsu-oriented catalog sources associate the 237-43-14190 HOSE KOMATSU with a broad range of GD-series graders. Across the catalog snippets and parts pages, the part appears with applications including GD28AC, GD300A, GD305A, GD355A, GD405A, GD510R, GD511A, GD521A, GD523A, GD600R, GD611A, GD621A, GD621R, GD623A, GD655A, GD661A, and GD663A. Some listings also show serial-range qualifiers, which means exact fitment should always be checked against the machine serial number rather than relying only on model family.

Examples from publicly visible catalog pages include:

• GD305A-1 S/N 6734-UP
• GD405A-1 S/N 50002-UP
• GD511A-1 S/N 10001-UP
• GD600R-3 S/N 14001-UP
• GD621A-1 S/N 10001-UP
• GD623A-1 S/N 30001-UP
• GD661A-1 S/N 10001-UP
• GD663A-2 S/N 1001-UP

Because some public catalogs are commercial resellers and some are catalog mirrors, it is safest to treat this list as a strong application guide rather than a substitute for serial-number verification. On heavy machinery, even a correct-looking hose can vary by length, end style, routing point, or production change. For that reason, buyers should confirm the old part number, machine model, and serial range before ordering the 237-43-14190 HOSE KOMATSU for service use.

Technical Details and Specification Summary

Publicly available data gives a useful working picture of the 237-43-14190 HOSE KOMATSU, even though different seller databases do not always display every field in the same way. The most consistent technical points are the part number, the alternate no-dash format, the 300 mm description, and its repeated appearance in grader brake-piping groups.

Weight in KG

Public sources do not show a perfectly identical number for weight. One Komatsu-oriented catalog page lists the 237-43-14190 HOSE KOMATSU at 0.165 kg, while another reseller catalog snippet shows 0.130 kg. Because both values are close and because catalog databases sometimes differ on bare-part versus listed-part handling, a practical working weight is approximately 0.13 to 0.17 kg, with 0.165 kg being the stronger repeated catalog figure.

Practical specification estimate based on sources and images

The 2374314190 hose can be described in practical terms as a short straight threaded hose assembly, approximately 300 mm long, used in grader brake-piping service, with a light individual part weight around 0.165 kg. That makes it a compact but functionally important line component rather than a bulk hose or a custom-cut workshop substitute.

Service Problems a Worn Hose Can Cause

The 237-43-14190 HOSE KOMATSU works in a fluid circuit, so deterioration should never be ignored. Even a small hose can create larger problems when it starts to fail. A cracked outer layer, damaged fitting thread, internal restriction, or seep at the end connection can reduce system reliability and create frustrating repeat service.

In grader maintenance, short hoses like the 237-43-14190 HOSE KOMATSU are often exposed to grime, dust, oil mist, vibration, and repeated pressure cycling. That means typical replacement reasons can include:

loss of flexibility,
surface cracking,
damaged end threads,
weeping around the crimp or fitting seat,
abrasion from nearby contact,
or replacement during line overhaul.

Even when the hose has not fully failed, a technician may choose to replace it during nearby brake-piping work because the labor access is already open and the cost of a second teardown later is higher.

Installation Considerations

Match the exact number

For a compact grader hose, part-number accuracy matters. The 237-43-14190 HOSE KOMATSU should be matched by full number and by application context, not by appearance alone. Two short threaded hoses can look almost identical in photos while differing in thread specification, working length, or fitting geometry.

Check surrounding hard lines and joints

Public catalog snippets show this hose appearing together with joints, unions, bolts, washers, clips, and tubes in brake-piping layouts. That suggests replacement should not focus only on the hose itself. If a line has been leaking or damaged, the technician should also inspect the mating joint faces, supporting clips, nearby rigid tubes, and any washers or connected hardware in the same area.

Avoid twist during fitting

Because the 2374314190 assembly is short, it is especially important that the hose is installed without unwanted twist. A twisted short hose can sit under constant stress, shortening service life and increasing the chance of premature cracking or seal trouble.

Why the 237-43-14190 HOSE KOMATSU Is a Smart Preventive-Replacement Item

Some parts are only replaced after catastrophic failure. The 237-43-14190 HOSE KOMATSU is different. It is usually smarter to replace this kind of short hose before it becomes a serious problem. The reason is simple: fluid-line leaks and connection failures rarely happen at a convenient time. They happen during operation, during pressure demand, or while the machine is needed most.

For fleet owners, workshops, and overseas buyers, keeping the right hose ready matters because a compact line part can still stop productive work. If the machine is down for a small hose that should have been replaced earlier, the real cost is not the hose itself. The real cost is downtime, delayed service, and lost operating hours.
