Full Brass Nickel Plated Push-in Fittings – BPOC, BPM, BPGJ & BPU Series

Brass Nickel Plated Push-in Fittings for Different Connection Requirements

A pneumatic system often requires more than a standard threaded connector. Tubing may need to pass through a panel, connect two different tube sizes, or join two pneumatic tubes in a straight line. The BPOC, BPM, BPGJ and BPU Series provide different structural solutions for these installation requirements while maintaining the same convenient push-in connection principle.

BPOC Series – Male Round Straight

Designed for direct tube-to-threaded-port connection. 

Its round straight structure is suitable for equipment and pneumatic components requiring a compact inline connection.

BPM Series – Bulkhead Straight

Designed for installations where pneumatic tubing must pass through a machine panel, enclosure or mounting plate. 

The bulkhead structure helps create an organized connection point between two sides of the installation surface.

BPGJ Series – Plug-in Reducer

Used to connect pneumatic tubing with different outer diameters. 

This configuration is useful when a system needs to transition between tube sizes without adding unnecessary connection components.

BPU Series – Straight Union

Provides a direct connection between two pneumatic tubes in a straight line. 

It is suitable for extending tubing, repairing pneumatic lines or joining separate sections of a system.

Features of Nickel Plated Brass Pneumatic Fittings

These brass push-in fittings combine a durable metal body with a practical push-to-connect structure for convenient installation and maintenance.

Applications for Brass Push-in Fittings

The BPOC, BPM, BPGJ and BPU Series are suitable for pneumatic systems requiring flexible tube routing and reliable connection between different components. Typical applications include industrial automation equipment, pneumatic control systems, packaging machinery, assembly equipment, air distribution lines and general machinery.

The BPM bulkhead fitting is particularly useful for machine panels and protective enclosures, while the BPGJ reducer can simplify transitions between different tubing sizes. BPOC and BPU designs are suitable for straightforward inline connections where compact and efficient tube routing is required.

Installation of Pneumatic Push-in Fittings

Installation is simple when the tubing is properly selected and prepared.

● Cut the pneumatic tube cleanly and squarely.

● Confirm that the tubing outer diameter matches the fitting specification.

● Insert the tube fully into the push-in fitting.

● For threaded connections, select the correct thread type for the equipment port.

● Avoid excessive side loading or sharp bending near the connection point.

By combining multiple straight and connection configurations, these brass nickel plated push-in fittings help engineers build cleaner, more adaptable pneumatic tubing systems with fewer unnecessary connection components.
