Push To Connect Round Straight

Compact Straight Pneumatic Connections for BSPT / R-Thread Systems

POC Series push-to-connect fittings are designed to connect pneumatic tubing in a compact straight arrangement to compatible BSPT / R-thread equipment. They provide a fast removable connection for compatible pneumatic tubing used throughout industrial automation and compressed air equipment.

The round straight format helps machine builders keep tubing layouts compact and serviceable. Correctly selected fittings can simplify installation around valves, cylinders, manifolds and control panels while allowing compatible tubing to be removed for maintenance after the circuit is safely depressurized.

Frequently Asked Questions

What is a round straight fitting used for?

It is used to connect pneumatic tubing in a compact straight arrangement to compatible BSPT / R-thread equipment in a pneumatic circuit.

How does a push-to-connect connection work?

Compatible pneumatic tubing is pushed into the fitting until the internal gripping and sealing components retain it. The tube is released using the collar after the system is safely depressurized.

What tubing is commonly used?

The source range identifies polyurethane and nylon pneumatic tubing as common materials. Always match tube outside diameter and material to the fitting.

What is the operating pressure?

The listed pressure range for this category should be confirmed against the exact model. The source data provides the category operating limits shown above.

Can these fittings be used for vacuum?

Yes, where the specific fitting and tubing are rated for the listed vacuum duty. Confirm the exact model before use.

Can the tubing be removed and reused?

Yes. Push-in fittings are designed for repeated tube connection and disconnection when used correctly and depressurized before service.

Where are these fittings commonly used?

They are used on pneumatic valves, cylinders, manifolds, machine panels and general industrial automation equipment.

How do I select the correct round straight?

Confirm tube outside diameter, BSPT thread size and installation length, together with pressure, temperature and tubing compatibility.
