Stainless Steel with Stainless Ball
Balls are 440 stainless.
The 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.
Plungers may be ordered with or without the locking element. Plungers without the element are the same price, but are considered “specials” and cannot be returned. We recommend using without the locking element for applications in aluminum.
To prevent possible spring damage, use of a Northwestern Wrench is recommended when installing from plunger end.
All stainless bodies are made of 303 material.
Part numbers ending in a “P” do NOT have a locking element.
