Automatic shut-off valve prevents air wastage during tool changes, saving energy and maintaining system pressure.
Ergonomic Operation
Smooth push-pull mechanism requires minimal force, reducing operator fatigue during frequent connections.
Long Service Life
Precision-engineered components resist wear and maintain seal integrity through thousands of connection cycles.
Safety Compliant
Meets ISO 4414 pneumatic safety standards for professional workshop environments.
Installation Guide
- Prepare Thread: Clean the G 1/4 male thread on your hose or equipment. Remove any debris or old sealant.
- Apply Sealant: Wrap 2-3 turns of PTFE tape clockwise on the male thread (optional for tapered threads).
- Hand Tighten: Thread the coupling onto the male fitting by hand until finger-tight.
- Final Torque: Use a spanner to tighten an additional 1-2 turns. Do not over-tighten.
- Pressure Test: Connect air supply and check for leaks using soapy water solution.
Compatibility Notes
This coupling features a G 1/4 BSP parallel female thread, the UK and European standard for pneumatic connections. It is compatible with:
- Standard UK air compressor outlets (G 1/4 male)
- European pneumatic hoses with G 1/4 fittings
- Schrader-type male plugs and adaptors
- ISO 228-1 compliant threaded components
Note: Not compatible with NPT (American tapered) threads without an adapter. Verify your system uses BSP parallel threads before ordering.
Maintenance & Care
- Inspect O-ring seals monthly for wear or damage
- Clean coupling body with compressed air to remove dust and debris
- Apply light machine oil to moving parts every 3 months
- Replace O-rings annually or when leaks develop
- Store in dry conditions when not in use to prevent corrosion
