Light Pressure
Steel noses are case hardened for wear resistance without brittleness.
Bodies are 12L14 steel with a black oxide finish.
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.
