Description
A-Style Quick Release Coupling
7.9mm (5/16″) I/D Hose Tailpiece
Professional-grade quick release coupling engineered for reliable, leak-free pneumatic connections. Premium brass construction delivers exceptional durability and corrosion resistance for demanding workshop environments.
Precision Engineering
Manufactured to exacting tolerances, this A-style coupling ensures consistent, secure connections every time. The 7.9mm (5/16″) internal diameter hose tailpiece provides optimal flow characteristics for compressed air applications up to 10 bar.
Premium Materials
Constructed from high-grade brass alloy for superior strength and longevity. The corrosion-resistant finish maintains performance integrity even in humid or industrial environments, whilst the precision-machined threads guarantee perfect sealing.
Universal Compatibility
A-style profile ensures broad compatibility across pneumatic tool systems. The standardised design integrates seamlessly with existing air line infrastructure, making it ideal for workshop upgrades or system expansions.

Installation & Maintenance
Installation Guidelines
- Ensure air line is depressurised before installation
- Apply PTFE tape to male threads (2-3 wraps clockwise)
- Hand-tighten coupling onto hose tailpiece until finger-tight
- Use appropriate spanner to tighten additional 1-1.5 turns
- Pressure test system at working pressure and check for leaks
Maintenance Recommendations
Inspect coupling quarterly for wear or damage. Clean external surfaces with degreaser to maintain smooth operation. Replace if thread damage or air leakage is detected. Store spare couplings in clean, dry conditions.
