Applications

Where This Fitting Excels

• Connecting air compressor manifolds and distribution blocks to 10mm airline runs
• Workshop pneumatic tool circuits — spray guns, impact wrenches, nail guns
• Industrial automation and machine pneumatic control systems
• Garage and bodyshop air line installations
• Agricultural and plant machinery pneumatic maintenance

Installation

Fit in Seconds

• Apply PTFE thread tape to the R 3/8 male thread and hand-tighten into the female port, then wrench-tighten 1–2 turns.
• Cut the 10mm tube to a clean, square end — no burrs.
• Push the tube firmly into the collet until it seats fully. A slight tug confirms lock.
• To release: depress the collet ring and withdraw the tube cleanly.
