MIL-H6000-1/2 - Textron Aviation OEM Hose Oil Coolant

MIL-H-6000 -8 (1/2") – Textron Aviation OEM Oil and Coolant Hose

Available now on the Airparts.aero Marketplace.

Overview

This product is a bulk, low-pressure fluid transfer hose that holds dual authority as a component manufactured to the Military Specification MIL-H-6000 and as a genuine Textron Aviation Original Equipment Manufacturer (OEM) part. It is specifically engineered for fabricating flexible hose assemblies used in aircraft engine oil and liquid coolant systems. This particular hose is the -8 (Dash 8) size, corresponding to a 1/2-inch inside diameter.

As a component supplied through the Textron Aviation channel, this MIL-H-6000 hose comes with the full assurance of OEM traceability and quality control. It is guaranteed to be the factory-approved bulk material for maintaining the type-certified design of Cessna, Beechcraft, and Hawker aircraft. Its multi-layer construction is designed to withstand the heat, pressure, and fluid exposure found in a piston engine compartment. This product is typically sold by the foot.

Key Features

• Textron Aviation OEM Certified: Guarantees the product is fully traceable and meets the quality standards required by the airframe manufacturer for their fleet.

• Compliant with MIL-H-6000: Manufactured and tested to meet all requirements of the military standard for low-pressure aircraft oil and coolant hose, ensuring quality and performance.

• For Low-Pressure Oil/Coolant Systems: Specifically designed for applications such as engine oil cooler lines, crankcase breather lines, and liquid coolant systems.

• Multi-Layer Reinforced Construction: Features a seamless inner tube, a high-strength braided textile reinforcement layer, and a durable outer cover for resistance to pressure and damage.

• Oil and Heat Resistant: The synthetic rubber compounds used in its construction are formulated for long-term resistance to the degrading effects of hot petroleum-based lubricating oils and ethylene glycol coolants.

Aircraft Compatibility

As a Textron Aviation OEM part, this bulk hose is the specified material for fabricating hose assemblies on a vast range of their piston-engine aircraft.

• Primary Textron Aviation Platforms:

  • Cessna Piston Aircraft (172, 182, 206, 210, etc.)

  • Beechcraft Piston Aircraft (Bonanza, Baron)

• General Aerospace Usage: As a mil-spec hose, it is a fundamental material for any certified aircraft requiring low-pressure oil/coolant lines.

Note: This is bulk hose material. Its applicability is determined by the specific hose assembly being fabricated, as defined by the aircraft or engine maintenance manual.

Applications

• Fabrication of flexible lines for engine oil coolers on Textron aircraft.

• Crankcase breather (breather) hose assemblies.

• Liquid coolant lines for engines so equipped.

• WARNING: Not for use in high-pressure hydraulic systems, fuel systems, instrument lines, or any application inside the aircraft cabin or cockpit.

Why Choose this MIL-H-6000 Hose?

This hose provides the dual assurance of meeting the public MIL-SPEC standard and the specific endorsement of Textron Aviation. The hose carrying an engine's lubricating oil is a flight-critical component. Using this certified hose is the only way to ensure the assembly is airworthy and is specifically formulated to resist bursting, swelling, and hardening when exposed to the engine environment. Sourcing the OEM part ensures you are using the exact material specified in the aircraft's original, type-certified design.

A critical aspect of airworthiness for a bulk hose product like MIL-H-6000 is its finite shelf life, which is determined by its cure date. Aerospace standard ARP5316 provides the guidelines for the storage and age control of aerospace elastomers, including bulk hose. The synthetic rubber compounds are not inert; they are subject to slow, irreversible chemical changes from exposure to oxygen, ozone, and UV light, even during storage. These changes cause the material to lose its plasticity, become brittle, and lose its ability to withstand pressure and flexing. For this reason, every certified aerospace hose is marked on its layline with the quarter and year it was manufactured (cured). A mechanic must verify that the hose is within its specified shelf life (e.g., 8-10 years for synthetic rubber hose, depending on storage) before it can be legally used to fabricate a new hose assembly. Installing an expired hose, even if it appears new, introduces a significant risk of premature, catastrophic failure.

Note: This is bulk hose material used to fabricate flight-critical hose assemblies. This product has a finite shelf life determined by its quarter/year of manufacture (cure date). Expired hose must not be used. Hose assemblies must be fabricated and installed by a certified A&P mechanic in strict accordance with standard practices (e.g., FAA AC 43.13-1B). The correct hose fittings and clamps must be used, and the final assembly must be pressure tested before installation. The hose must be routed to prevent kinking, chafing, and exposure to extreme heat sources.
