ABSTRACT:
An integrally molded plastic lubricant fitting which has the check valve at the outlet of the fitting instead of at the inlet, and where hydrostatic pressure from the lubricant within the body of the fitting maintains the fitting in an operative position. The latter is further assured through the provision of circumferential ribs on the outer surface of the body of the fitting, such coacting with the inner surface of a predrilled fitting hole in a positive manner.
