These fittings are also known as hydraulic grease fittings.
303 stainless steel fittings are more corrosion resistant than brass fittings and have good chemical resistance. 316 stainless steel fitting is more corrosion and chemical resistant than 303 stainless steel fittings and can be used in saltwater environments.
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. UNF and UNEF threads are similar to threads on a machine screw or bolt. They require a sealant, such as an O-ring, to minimize leakage. SAE-LT threads are tapered but designed to be installed into a 1/4"-28 straight-thread UNF hole.

Often used on earth movers, mining equipment, and other heavy machinery, these fittings have a T-shaped top that holds the dispensing tip in place so it won’t pop off when adding grease. An integral check valve prevents grease from leaking when pressure causes backward flow. The valve stays closed when not in use to keep out dirt and other contaminants.
303 stainless steel fittings are more corrosion resistant than zinc-plated steel fittings and have good chemical resistance.
PTF and NPTF (Dryseal) threads are compatible with NPT threads.

Drive these fittings into unthreaded holes with a hammer and grease fitting installation tool (sold separately). They're also known as hydraulic grease fittings.
Fittings with a serrated shank have a tighter grip than those with a smooth shank for a more secure fit in old or oversized holes. 303 stainless steel fittings are more corrosion resistant than zinc-plated steel fittings and have good chemical resistance.
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.
