Why this coupler
- 10,000 PSI static rating — which means it handles extreme high-pressure applications like portable hydraulic rams and porta-power tools.
- Threaded union locking — which means the halves screw together for a positive, vibration-proof connection that will not blow apart under pressure.
- Chrome alloy ball check valves — which means spring-loaded, metal-to-metal sealing for reliable shut-off at extreme pressure.
- Polyurethane body seal — which means resistance to high-pressure extrusion for long seal life.
- Machined from solid steel bar stock — which means maximum strength and durability.
