Description
Precision Pneumatic Fittings
8mm Brass Tube-to-Tube Straight Coupling
Engineered for reliability. Designed for speed. Built to last.
The 8mm Tube-to-Tube Straight Coupling delivers seamless inline connections between two sections of 8mm pneumatic tubing. Precision-machined from solid brass, this push-fit connector eliminates the need for tools, thread tape, or clamps — simply push the tube in for an instant, leak-proof seal rated to 16 bar.
Whether you're extending an air line in a busy workshop, repairing a damaged section of tubing on production machinery, or building a new pneumatic circuit from scratch, this coupling provides the professional-grade connection you need with zero compromise on flow or pressure integrity.

Frequently Asked Questions
What tube size does this coupling fit?
This straight coupling is designed for 8mm outside diameter (OD) pneumatic tubing, including nylon and polyurethane tube types commonly used in compressed air systems.
Do I need any tools to install this fitting?
No. This is a push-fit connector — simply cut your tube square, push it firmly into the fitting until it clicks, and you have a secure, leak-proof connection. No spanners, tape, or adhesives required.
Can I use this with compressed air?
Yes. Rated to 16 bar (232 psi), this coupling is specifically engineered for compressed air and pneumatic systems in workshop, industrial, and automotive environments.
Is this fitting reusable?
Yes. Press the collet release ring and pull the tube out to disconnect cleanly. The fitting can be reused multiple times without degradation to the seal or body.
