Air Brake Hose Male Adapter

Male Adapter is a key adapter component in the D.O.T. Air Brake series, mainly used for connecting high-pressure air circuits in air brake systems, achieving the conversion of different interface standards or sizes while maintaining sealing and durability.

(1) Interface conversion and adaptation

Convert different thread standards (such as M22 → NPT, BSPP → UNFPA) to solve equipment compatibility issues in different regions around the world.

Connect the hose to the hard pipe (such as connecting the inverted hook of the hose to the metal hard pipe).

 

(2) High pressure sealing performance

Metal cone sealing: By precisely machining the cone surface and pressing it against the matching nut, a leak free connection is achieved.

O-ring assisted sealing (some models): Fluororubber (FKM) or Nitrile Rubber (NBR) provide additional sealing protection.

 

(3) Anti vibration and anti loosening

Locking structure: Some models come with locking nuts or elastic washers to prevent thread loosening caused by vibration.

High strength brass: resistant to creep and maintains stable sealing even after long-term use.

 

(4) Reusable

Support multiple disassembly and assembly (50+times), no need to replace during maintenance, reducing operating costs.

 

 

Application Fields	Specific Use
Commercial vehicle braking system	Connect the brake valve, air storage tank, and trailer emergency brake pipeline to adapt to equipment with different interface standards.
Cconstruction machinery	The multi-channel pneumatic distribution system for excavators and loaders solves the connection problem between rotary joints and fixed pipelines.
Rail Transit	The connection between the main brake air duct and the branch pipeline of the train ensures reliable sealing of the high-pressure air circuit.
Special vehicles	The corrosion-resistant gas system of fire trucks and mining trucks is made of stainless steel material to adapt to harsh environments.
After sales maintenance	Quickly replace damaged pipeline interfaces at the repair station without the need to replace the entire brake system components.
