The coupling that professional workshops trust — engineered for speed, built to last.

The A Style Quick Release Coupling with 9.5mm (3/8″) hose tailpiece is the industry-standard choice for pneumatic air line systems across automotive workshops, fleet maintenance bays, and industrial production environments. Machined from solid brass for corrosion resistance and long service life, this coupling delivers a positive, leak-free connection every time — with one-handed operation that keeps your workflow moving.

Designed to the A Style (Euro) coupling standard, it mates reliably with all compatible A Style plugs and sockets. The 9.5mm (3/8″) internal diameter hose tailpiece accepts standard 3/8″ bore air hose, making it the go-to fitting for medium-duty air tools including impact wrenches, ratchets, spray guns, and blow guns.

• Instant Connect/Disconnect — Spring-loaded sleeve mechanism allows one-handed coupling and release without tools, reducing downtime between tasks.
• Precision Brass Construction — Solid brass body resists corrosion, withstands workshop chemicals, and maintains dimensional accuracy over thousands of cycles.
• 300 PSI Rated — Engineered to handle the full pressure range of industrial and trade compressors, from small workshop units to high-capacity systems.
• A Style (Euro) Standard — Universally compatible with all A Style plugs and sockets; the most widely adopted coupling standard in UK and European workshops.
• 9.5mm (3/8″) Hose Tailpiece — Barbed tail secures firmly to 3/8″ bore air hose with a hose clip, providing a vibration-resistant, leak-free seal.
• Leak-Free Seal — Internal valve design ensures an airtight connection under load, maintaining consistent tool performance and reducing compressor cycling.
