Engineering Advantages
- Solid Brass Body — Corrosion-resistant and built to withstand the rigours of daily workshop use, delivering a service life that outlasts cheaper zinc-alloy alternatives.
- Precision 8V1 Thread — Machined to exact tolerances for a positive, rattle-free engagement on all standard Schrader-type tyre valves found on cars, vans, trucks, and motorcycles.
- Open-End Design — Allows continuous airflow during inflation and deflation without the need to depress the valve core manually — faster, cleaner, more efficient.
- 6.35mm (¼″) Hose Tailpiece — Industry-standard bore size compatible with the vast majority of workshop air hoses, PCL hose assemblies, and aftermarket air lines.
- 300 PSI Rated — Exceeds the pressure requirements of all passenger and commercial vehicle tyres, providing a substantial safety margin for high-pressure applications.
- Vibration-Resistant Seal — The screw-on mechanism maintains a secure, leak-free connection even under the vibration of a running compressor or busy workshop environment.
