Stainless Steel with Delrin Nose
All stainless parts are made of 303 material.
The nylon locking element holds the plunger body securely in place without the need for lock nuts or other devices. We recommend a 90 degree countersink 1/32″ larger than the major diameter of the mating thread to prevent damaging the element.
All part numbers that end with a “P” do NOT have a locking element.
To prevent possible spring damage, use of a Northwestern Wrench is recommended when installing from plunger end.
