Grease Fittings (Zerk Fittings)


They are small and inconspicuous, but responsible for keeping machines and all kinds of equipment in motion – whether in a harvester in Europe, a pipeline in Alaska, or a brewery in Australia.

There is a grease nipple from us for every application in most sizes, types and composition.  With a range of more than 1,500 different types of nipples with about 70 different thread types we offer the largest product line worldwide.

Depending on the application and the installation sizes, we can manufacture grease nipples according to international standards. Other than a standard version made of steel, zinc-plated and passivated, we offer many other types, made of brass or stainless steel.

To avoid abrasion wear and blowout, our products are case hardened and rated minimum surface hardness 550HV (including the head, body and thread), case depth 0.13mm-0.23mm, maximum pressure >5,000 psi.  Our SAE series grease nipples are rated specific surface hardness of 83 HR 15 N minimum according to Rockwell hardness.
