UB Series American Type B Universal Quick Couplings

Multi-Profile Compatibility in One UB Series Coupling

The UB Series American Type B Universal Quick Coupling is designed to connect with several commonly used pneumatic plug profiles. One socket can accept compatible IN20, TR20 and AR20 plugs, helping simplify equipment connections where different standards are used.

Compact Construction with Six-Ball Retention

Compared with the UA Series, the UB20 has a smaller, lighter body and a lower flow rate. Its six-ball locking structure helps retain the plug during operation, while the push-to-connect sleeve supports convenient one-hand connection.

● Standard: ISO 6150-B

● Body size: 1/4 inch

● Maximum working pressure: 2.0 MPa

● Temperature range: -10°C to +70°C

● Materials: Brass, nickel-plated carbon steel or stainless steel

Pneumatic Applications and Installation

UB Series quick couplings are suitable for air compressors, pneumatic tools, workshop air lines and general maintenance equipment.

Available socket connections include female NPT, male NPT and standard hose barb. Match the plug profile and connection size before installation, then push the plug into the socket until securely engaged. For applications requiring higher airflow, consider a larger-flow coupling series.
