Product Description

Railway Air Brake Hose Connector System

Professional railway air brake hose coupling connector designed to UIC standards for connecting brake pipeline and feed pipeline/MR pipeline throughout the train. The coupling heads for feed pipe/MR coupling hoses feature opposite design to brake pipe coupling hoses for secure connections.

Key Components

Sealing Washer: Prevents unacceptable air loss when two coupling heads are connected

Brake Coupling Head: Mechanical components allowing pressurized air flow between connections

Hose Clip: Mechanically fixes hose to coupling head or nipple

Hose: Flexible component conveying pressurized air between vehicles

Nipple: Component connecting pneumatic half coupling to end cock or vehicle pipe

Hose Construction

Tube: Interior layer of flexible hose

Reinforcement: Intermediate layer providing strength while maintaining flexibility

Covering: External protective layer against mechanical and environmental damage
