Why Professionals Choose A-Style Couplings
A-Style couplings have become the UK workshop standard for good reason. The robust locking mechanism prevents accidental disconnection under load, while the automatic shut-off valve stops air loss when tools are removed. Unlike cheaper alternatives, genuine A-Style fittings maintain consistent performance across temperature extremes and resist contamination from workshop debris.
The R 1/2" thread size strikes the perfect balance between flow capacity and compact dimensions, making it ideal for general workshop applications where both portability and performance matter.
Installation Guide
- Prepare the Thread: Clean the female thread on your air line or manifold. Apply PTFE tape (3-4 wraps clockwise) for a gas-tight seal.
- Hand Tighten: Thread the coupling in by hand until finger-tight. Avoid cross-threading.
- Final Tightening: Use a spanner on the hex flats to tighten 1-2 turns beyond hand-tight. Do not over-tighten.
- Pressure Test: Connect your air supply and check for leaks using soapy water. Tighten slightly if needed.
System Compatibility
