Grease Fitting Adapters
When the size or thread type of a fitting doesn't match an existing opening, use these adapters to make the connection.
Intermittent swivel adapters rotate to make it easier to access your fitting in tight spaces.
Zinc-plated steel adapters have mild corrosion resistance. Brass adapters resist corrosion better than zinc-plated steel adapters. 303 stainless steel adapters are more corrosion resistant than brass adapters and have good chemical resistance.
PTF-SAE and NPTF (Dryseal) threads are compatible with NPT threads. UNF 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.
