Engineered with a narrow profile for tight clearances, this hydraulic coupler manages lubricant transfer at pressures up to 10,000 psi. An integrated check valve prevents leakage when disconnected, while the internal rubber seal maintains a secure seat on the fitting. The 1/8" NPTF(f) threaded inlet provides a standard connection point for grease gun extensions and hoses.
