High-Temperature Resistant Pneumatic Brake Hose — Dedicated Braking Protection For Extreme Heat Conditions

Heavy-duty trucks, construction machinery and special vehicles are always in high temperature environments in their engine compartments and brake drums. In these areas standard pneumatic hoses fail due to softening, ageing, air leaks and other defects which seriously impair braking safety. Our High-Temperature Resistant Pneumatic Brake Hose is specially developed for extreme heat conditions to effectively solve the high-temperature failure problems of traditional hoses.

 

The product has an improved high-temperature resistant composite structure, fully optimised for extreme heat environments:
 

• Inner Layer: Special rubber with modified high temperature resistance can withstand continuous medium temperatures up to 250°C. It's perfectly suited for the high temperature air transmission path from the air compressor to the air reservoir.

 

• Middle Layer: Braid of special high temperature resistant fibre. It does not soften or deform under extreme heat, always maintaining structural strength and pressure stability.

 

• Outer Layer: Additives are added to improve the anti-thermal-oxidative ageing performance, which can effectively prevent the hose from suffering thermal radiation and oxidative corrosion, and prevent the hose body from cracking or peeling.

 

 

 

This product offers great advantages over conventional hoses in terms of heat resistance and thermal fatigue resistance:

 

 

• Wide Temperature Range: Reliable use over a wide temperature range (-40°C to 250°C), offering flexibility at low temperatures and stability at high temperatures.

 

• Thermal Fatigue Resistance: The hose body has undergone rigorous hot & cold thermal cycling tests and shows no delamination, separation or blistering. Its impulse fatigue life is beyond the industry standards.
• Secure Sealing: The fittings are manufactured using a proprietary high temperature sealing process that prevents loose seals, air leaks or pressure drop due to thermal expansion and contraction.

 

 

 

It is mainly developed for the high-temperature pneumatic brake lines of heavy-duty/heavy-load vehicles and construction machinery. It specifically targets the pipeline ageing due to long-term downhill continuous braking and engine thermal radiation, and effectively reduces the brake failure rate and guarantees reliable braking safety protection during high-intensity operations in high-temperature environment.
