Grease Fittings
These fittings are also known as hydraulic grease fittings.
Monel fittings are the most corrosion resistant and can be used in caustic environments, such as those involving salt water, sulfuric acid, and alkalies.
Fittings with a check valve prevent grease from leaking when pressure causes backward flow. The valve stays closed when not in use to keep out dirt and other contaminants.
PTF and NPTF (Dryseal) threads are compatible with NPT threads. SAE-LT threads are tapered but designed to be installed into a 1/4"-28 straight-thread UNF hole.
