Description
PF Coupling — Female Thread Rp 1/2
Precision Quick-Connect Pneumatic Fitting
Engineered for professional workshop environments where reliability under pressure is non-negotiable. Instant connect and disconnect — without tools, without compromise.
Built for the Demands of Professional Compressed Air Systems
The PF Series female coupling with Rp 1/2 thread is the standard of choice for trade workshops, fleet maintenance bays, and industrial production lines across the UK. Its precision-machined brass body resists corrosion and mechanical wear, while the hardened steel locking sleeve delivers thousands of connect-disconnect cycles without degradation. Fit it once — rely on it indefinitely.
Compatibility Note: This coupling is designed to mate with all standard PF series male plugs. Ensure your existing airline fittings are PF series before ordering. Not cross-compatible with Euro (PCL) or US Milton series without an adaptor.
Key Features
CNC-machined from high-grade brass for superior corrosion resistance and dimensional accuracy across the full pressure range.
Engineered for high-cycle durability. The locking mechanism engages positively and releases cleanly — even under residual line pressure.
Oil-resistant nitrile seals maintain an airtight connection across a wide temperature range, suitable for lubricated and dry air systems.
Parallel internal thread (ISO 228) for a reliable, leak-free connection to manifolds, regulators, hose tails, and airline outlets.
Exceeds the operating pressure of virtually all workshop compressors, providing a substantial safety margin for demanding applications.
Single-handed connect and disconnect in under a second. Designed for high-frequency use without operator fatigue or connection errors.
