Phoenix Industries, a leading Double Ball Check Grease Fittings Supplier in USA, Canada, offers precision-engineered lubrication solutions built to perform in the most demanding industrial environments. Our fittings are specially designed for high-pressure applications in valves—such as plug valves and regulating valves—where reliability, safety, and leak prevention are critical.
Our fittings are purpose-built for systems operating under extreme pressure, ensuring consistent lubrication without the risk of blowback or failure.
Unlike standard single-ball fittings, our double ball design offers enhanced protection. The dual-check system ensures that grease only flows in the intended direction—effectively preventing backflow.
The first ball is spring-loaded to stay securely seated, maintaining a tight seal when the fitting is not in use. This design minimizes leakage and guarantees system integrity.
Engineered for critical applications, these fittings provide a robust sealing mechanism, ensuring the safety of equipment and operators alike.
Available in various thread standards, including NPT (tapered) and UNF (straight) threads, our fittings suit a wide range of industrial applications.
For ease of maintenance, we offer variants with a giant button head—compatible with standard grease gun couplers for quick and efficient lubrication.
Ideal for plug and regulating valves, our fittings ensure proper lubrication and minimize internal leakage—extending the service life of critical components.
The double check system maintains tight seals even in high-pressure scenarios, helping prevent costly system leaks.
With zero tolerance for backflow, these fittings protect internal components and preserve the integrity of your mechanical systems.
