Heavy Haul Test 15 Coupler, 1/4″ BSP Male Thread, Ball Check Valve, Buna-N Type C Elastomeric Seal, Hexagonal Cap

Built for high-pressure diagnostics, this Summit Hydraulics Test 15 Coupler features a 1/4″ BSPP male thread and an integrated ball check valve for safe and easy connection to pressure gauges, sensors, and diagnostic tools. The Buna-N elastomeric seal (Type C) ensures reliable sealing during pressurized operation, while the hexagonal steel cap provides added protection in high-vibration environments.

With a pressure rating up to 9,137 PSI and connect-under-pressure capability up to 9,137 PSI, this coupling is ideal for hydraulic test points in mobile and industrial systems. Its zinc-nickel plated steel body offers long-term corrosion resistance and performance in heavy haul applications or tough field conditions.
