Gates Air Brake Hose
Gates G33705-0502 Air Brake Rubber Hose Male Flareless to Male Pipe Shut-Off Assembly
Gates Air Brake Hose: Engineered for the Demands of Heavy-Duty Applications
When the braking system of a commercial truck, bus, or trailer is on the line, the hose connecting compressed air to the brakes is not a component to compromise on. Gates has built a well-earned reputation as one of the most trusted names in fluid power and engine hose technology, and their air brake hose lineup reflects that same commitment to precision engineering and regulatory compliance. From OEM fleets to independent service shops, Gates air brake hoses are a go-to solution for professionals who need reliability under pressure — literally.
A Lineup Built Around Compliance and Performance
Gates offers several distinct air brake hose product lines, each designed to meet or exceed the federal and industry standards that govern air brake systems in commercial vehicles.
- AB Series Rubber Air Brake Hose: Gates' AB Series features a computer-controlled manufacturing process for consistent product uniformity, with four-spiral fiber reinforcement, an EPDM rubber construction, and compliance with SAE J1402. Working pressure is rated at 225 PSI with a burst pressure of 1,000 PSI, and the temperature rating spans -40°F to +212°F.
- Green Stripe™ Vacuum Brake Hose: The Green Stripe™ is an extra heavy-duty hose designed to fit most air brake systems on trucks, trailers, and other heavy equipment, recommended for truck, bus, and mobile air brake systems, and usable as a flexible connector between frame and axle.
- TR500 High-Temperature Air Brake Hose: The TR500 is recommended for air brake hose applications, high-temperature pressurized oil return lines, rotary oil/air compressor lines, and engine and transmission coolant lines.
- C5E High-Temp Flexline™: The C5E High-Temp Flexline™ hose is recommended for air brake hose, power steering on heavy-duty commercial vehicles, engine and transmission coolant lines, and hot lube oil lines up to +300°F.
- Nylon Air Brake Tubing: Recommended for truck, bus, and mobile air brake and service lines where heat and battery acids are not present, this tubing conforms to SAE J844 specifications and meets DOT FMVSS 106-74.
Factory-Crimped Assemblies for Fleet Reliability
Gates factory-crimped air brake hose assemblies meet the rigorous demands of the fleet and heavy-duty market — they are extremely flexible and kink resistant, built with four-spiral construction that meets SAE J1402 specifications, comply with DOT FMVSS 106 requirements, and feature couplings that meet SAE and DOT minimum pull-off requirements. This level of out-of-the-box readiness reduces installation time and limits the risk of field assembly errors.
High-Temperature Capability and Abrasion Resistance
With covers that resist abrasion and tubes engineered to handle hot engine air, Gates high-temperature air brake hoses are designed for the toughest applications, helping operators meet environmental controls against hydraulic leakage and strict emissions standards. This makes them especially valuable in modern diesel-powered commercial vehicles where underhood temperatures and emissions compliance are constant concerns.
Compatible Coupling Solutions
Gates does not stop at the hose itself. Their air brake ecosystem includes purpose-matched fittings. The SureLok™ Air Brake couplings are simple to install — just press to connect for a secure, long-lasting fit with simple tube connection and disconnection. The composite fittings are up to 70 percent lighter than comparable brass fittings and meet DOT FMVSS 571.106, SAE J113, and SAE J2494 impact resistance standards. For rubber hose assemblies, Gates Air Brake Couplings for Rubber Hose are designed for use with AB Series rubber air brake hose on truck and bus air brake systems, and many fittings can be detached and reattached for reuse.
Whether you are maintaining a long-haul fleet or servicing a single commercial truck, Gates air brake hose products deliver the engineering depth, regulatory compliance, and durability that safety-critical brake systems demand.
