........and now we know why!

The *Zerk* design, *named* after Oscar *Zerk*, used a *fitting* much
smaller than the Alemite pin-type and did not lock the hose coupler or hand
gun and *fitting* together. Instead, the seal between them was maintained
by the pressure of a pushing action when the operator applied the coupler
to the *fitting*.
