Description
Air Compressors UK — Professional Pneumatic Fittings
The 4.75mm (3/16") Steel
Air Hose Tailpiece Adaptor
A precision-engineered barbed adaptor built for demanding compressed air environments. Rated to 14 bar / 200 psi with a 43 cfm flow rate — engineered to connect, seal, and hold.
In a compressed air system, the weakest link is always the connection. This 4.75mm (3/16") steel hose tailpiece adaptor eliminates that vulnerability. Its ribbed barb profile bites firmly into the hose bore, creating a mechanical grip that resists pull-out forces and pressure surges — without relying on clamps alone. Whether you're fitting out a workshop air line, servicing a tyre inflation bay, or building a pneumatic tool circuit, this adaptor delivers the reliability that professional environments demand.

Installation Guide
- Depressurise the system — isolate and bleed the air line before beginning any fitting work.
- Cut the hose cleanly — use a sharp hose cutter to ensure a square, burr-free end on your 4.75mm ID air hose.
- Lubricate the barb — apply a small amount of silicone grease or soapy water to ease insertion without damaging the hose bore.
- Push firmly onto the barb — insert the tailpiece fully until the hose seats against the shoulder of the fitting.
- Secure with a hose clamp — for pressurised applications, fit an appropriately sized worm-drive or ear clamp over the hose end.
- Pressurise and inspect — slowly re-introduce air pressure and check for leaks at the connection point before returning to service.
