The grease coupler with hex is for use with most hand-operated grease guns and equipment, fits all 1/8 inches NPT threads, has a 6, 000 PSI (414 bar) maximum operating pressure, and a hex body for easy installation and removal. The built-in spring-loaded ball check valve prevents leak, pressure loss and lubricant backup, has four hardened steel jaws for a superior seal and longer life. The precision fit enables a slight pushing action to snap jaws onto fittings, and is zinc plated for maximum protection against corrosion.
