BR series british type pneumatic quick couplings

British Industrial Profile with Manual Connection

BR Series British type pneumatic quick couplings are designed for compressed-air systems using the PCL 60 or Parker-Rectus 19 connection profile. The BR20 model features a 1/4-inch body and a manually operated sleeve. Unlike push-to-connect couplings, this design requires the operator to pull back the sleeve when connecting or releasing the plug.

The extended stem on both the socket and plug helps maintain a secure connection during equipment operation. Its self-sealing socket also shuts off the air supply when disconnected, helping reduce unintended air loss.

Four-Ball Locking for Secure Air Connections

The BR20 uses four stainless steel locking balls to retain the plug. Its metal construction is suited to regular industrial use, while different material and surface-finish options support varied equipment requirements.

Key specifications include:

● Working pressure: Maximum 2.0 MPa

● Temperature range: -10°C to +70°C

● Body size: 1/4 inch

● Locking mechanism: Four stainless steel balls

● Materials: Brass, carbon steel or SUS304/303 stainless steel

● Finishes: Zinc-plated or nickel-plated options for carbon steel components

Applications in Workshops and Industrial Equipment

These British profile quick couplings are suitable for air compressors, pneumatic hand tools, lawn mowers, spraying equipment and general workshop air lines. They provide a practical option for equipment already using PCL 60 or Series 19 plugs.

Socket and Plug Options for Installation

BR20 configurations include:

● Female and male threaded sockets

● Standard hose barb sockets

● Female and male threaded plugs

● Standard hose barb plugs

Select the matching socket and plug profile, thread size or hose diameter before installation. Secure threaded connections with a suitable sealing method, and check for leakage under operating pressure. Pull back the sleeve to connect or disconnect, and always release line pressure before servicing the coupling.

For larger airflow requirements, consider the IN30 or IN40 series.
