Overview

The definitive push-fit stud coupling for 1/8" BSP threaded ports and 4mm pneumatic tubing — engineered for professionals who cannot afford a leak.

Whether you are routing a precision automation circuit or commissioning a workshop air line, this stud coupling delivers the connection integrity your system demands. The 1/8" BSP male thread seats firmly into manifolds, valves, and cylinder ports, while the push-fit collet grips 4mm OD tubing instantly — no tools, no PTFE tape on the tube side, no wasted time. Release is equally effortless: depress the collet ring and the tube withdraws cleanly, ready for repositioning or replacement.

Installation Guide

Thread connection: Apply PTFE tape to the 1/8" BSP male thread and hand-tighten into the receiving port, then secure with a spanner — do not overtighten. Tube insertion: Ensure the 4mm OD tube is cut cleanly and squarely. Push firmly into the collet until it seats fully — you will feel a positive click. Tube release: Depress the collet ring evenly and withdraw the tube in a single smooth motion.
