Why haven’t we thought of it before? It’s a great question.

In 1929, Mr. Oscar Zerk invented his famous grease adaptor commonly known as a “Zerk”.  Since then, very little innovations have been seen. In 2013, Univer-Co launches a revolutionary product for the lubrification of “Zerks”. A simple attachment method, quick, leak proof and can support up to 10 000 psi.


  • Easy to handle;
  • Univer-Co (2013) inc’s lock-on grease coupler won’t leak and can resist up to 10 000 psi;
  • Because of its small size, you can reach very small spaces.
