Full Brass Nickel Plated Push-in Fittings – BPV, BPE, BPY, BPW & BPZA Series

Brass Push-in Union Fittings for Pneumatic Line Distribution

Pneumatic tubing systems often require more than a simple point-to-point connection. Air lines may need to change direction, divide into multiple branches, or connect several tubes at a central point. These brass push-in union fittings provide different connection geometries to support more organized pneumatic routing.

BPV Series – Elbow Union

The BPV Series connects two pneumatic tubes at a 90-degree angle. 

It is suitable for installations where tubing needs to change direction while reducing unnecessary bending or excessive tube length.

BPE Series – T Branch Union

The BPE Series provides a three-way T-shaped connection for dividing or combining pneumatic tubing lines. 

It is useful for creating branch connections in compact pneumatic systems.

BPY Series – Y Branch Union

The BPY Series uses a Y-shaped configuration to connect and distribute tubing in angled directions, providing an alternative layout where a standard T-shaped connection is not suitable.

BPW Series – Y Branch Union

The BPW Series also provides a Y branch connection for pneumatic tubing. 

Its configuration offers another option for routing air lines where branching direction and installation space require a different layout.

BPZA Series – Cross Union

The BPZA Series provides a four-way connection point for joining multiple pneumatic tubes. 

It is suitable for air distribution systems requiring several lines to be connected from a central position.

Features of Nickel Plated Brass Pneumatic Union Fittings

These brass push-in fittings are designed for reliable pneumatic tube connections across a wide range of industrial applications.

Brass body with nickel-plated surface

Suitable for compressed air, gas and vacuum

Working temperature: -20°C to +80°C

Working pressure range: 0–20 Bar

Compatible with PA11, PA12, PA6, PE and PU tubing (98 Shore A)

Recommended tubing tolerance: ±0.1 mm

Available connection options including elbow, tee, Y branch and cross union structures

The nickel-plated brass construction provides a durable fitting body, while the push-in connection system allows pneumatic tubing to be installed and removed more conveniently during equipment assembly or maintenance.

Applications of Pneumatic Union Fittings

These pneumatic union fittings are widely used where compressed air lines need to be routed or distributed between multiple components. Typical applications include industrial automation equipment, pneumatic control cabinets, packaging machines, assembly systems, air distribution networks and general factory machinery.

Elbow and branch fittings can help reduce complicated tubing layouts by allowing connections to follow the available installation space. Tee, Y and cross union designs are particularly useful when one pneumatic supply line needs to serve multiple downstream components.

Installation of Brass Push-in Tube Connectors

For reliable installation, use tubing with the correct outside diameter and recommended tolerance.

Cut the tube cleanly with a square end.

Select the appropriate union structure for the required tubing direction.

Push each tube fully into the fitting connection.

Avoid excessive pulling, twisting or sharp bending close to the fitting.

Check all connections before operating the pneumatic system.

With multiple elbow and branch configurations available, the BPV, BPE, BPY, BPW and BPZA Series provide flexible solutions for connecting and distributing pneumatic tubing while helping maintain a cleaner and more efficient system layout.
