Professional Pneumatic Fittings · UK Stock
Twin Hold-On
Tyre Valve Connector
Female Rp 1/4 BSP Parallel Thread · Brass Body · Nickel-Plated · 10 Bar Rated
Engineered for workshop professionals and mobile tyre technicians who demand a secure, repeatable connection every time. This twin hold-on connector grips standard Schrader valves instantly — no threading, no fumbling — while the female Rp 1/4 BSP parallel thread integrates cleanly into any UK or European pneumatic circuit. Built from brass with nickel-plated steel spring jaws, it is rated to 10 bar (145 psi) and supplied in trade carton quantities.
Why Professionals Choose It
Four Reasons This Connector Earns Its Place
Instant Hold-On Grip
Twin spring-loaded jaws lock onto the valve stem in one push — connect and disconnect in under a second, even in confined spaces or at awkward angles.
Universal Rp 1/4 Thread
Female Rp 1/4 BSP parallel thread (BS 2779 / ISO 7-1) mates with standard UK and European air hoses, gauges, and inflation guns without adapters.
Leak-Free Under Pressure
Precision-machined sealing faces and a robust spring mechanism maintain an air-tight seal up to 10 bar (145 psi), eliminating pressure drop and wasted air.
Trade Carton Packaging
Supplied in bulk carton quantities — ideal for workshop inventory, fleet maintenance programmes, and trade resellers requiring consistent stock levels.

Step-by-Step
Installation & Usage Guide
-
1
Thread ConnectionApply PTFE tape to the male Rp 1/4 fitting on your air hose or gauge. Hand-tighten into the female thread of the connector — do not over-torque.
-
2
Valve AttachmentAlign the twin jaws with the tyre valve stem and push firmly. The spring-loaded jaws grip automatically and lock in place.
-
3
Pressure VerificationListen for air leaks. A correctly seated connector will be silent under pressure. Check with soapy water if in doubt.
-
4
DisconnectionPull back the outer sleeve to release the jaws, then withdraw cleanly from the valve stem.
-
5
Ongoing MaintenanceInspect jaws periodically for wear. Clean debris from sealing surfaces. Lubricate sparingly with pneumatic-grade oil if stiffness develops.
System Integration
Compatibility & Thread Notes
This connector uses a female Rp 1/4 BSP parallel thread, designed to accept male Rp 1/4 fittings found on:
- Standard UK air hoses with male quick-release couplers
- Tyre pressure gauges with male Rp 1/4 threaded outlets
- Inflation guns and blow guns with Rp 1/4 male threads
- Manifold blocks and compressed air distribution systems
⚠ Rp threads are parallel (non-tapered). Always use PTFE tape or thread sealant for an optimal seal. Not directly compatible with NPT (tapered) threads — use an appropriate adapter if required.
