Professional Pneumatic Fittings — A-Style Range
A-Style Quick Release Coupling
7.9mm (5/16″) I/D Hose Tailpiece
Precision Brass Construction · 10 Bar Rated · UK Stock
Engineered for professional workshop environments where reliability is non-negotiable, this A-Style quick release coupling delivers fast, tool-free pneumatic connections with zero compromise on pressure integrity. Machined from solid brass and finished to resist corrosion in demanding industrial conditions, it accepts 7.9mm (5/16″) internal diameter hose via a secure barbed tailpiece — the standard choice for compressed air lines across automotive, manufacturing, and maintenance applications.
“The A-Style coupling is the most widely adopted pneumatic quick-connect standard in the UK and Europe — chosen by professional workshops for its proven push-to-connect mechanism, robust brass body, and compatibility across major tool brands.”
Technical Specifications
Why Professionals Choose This Coupling
- Instant push-to-connect release — change tools and attachments in seconds without shutting down the air supply, keeping your workflow uninterrupted on the workshop floor.
- Solid brass construction — resists corrosion, handles thermal cycling, and outlasts zinc or aluminium alternatives in high-use environments.
- 10 bar maximum working pressure — rated well above typical workshop compressor outputs (6–8 bar), providing a genuine safety margin under sustained load.
- Barbed hose tailpiece design — creates a mechanically secure, leak-free seal on 7.9mm (5/16″) I/D hose without the need for additional fittings or thread tape.
- A-Style universal compatibility — pairs with all A-Style adaptors, blow guns, tyre inflators, sanders, grinders, and air tools across major brands.
- UK stock, fast dispatch — held in our Manchester warehouse and shipped promptly to minimise downtime for trade and workshop customers.
