Light Pressure
Improved design allows plunger nose to be locked in a fully retracted position. Plunger nose has a chamfered end to assure easy alignment.
Steel parts are 12L14 material, heat treated and zinc plated.
All stainless steel parts are 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.
Plunger can be withdrawn completely into the body and locked in a fully retracted position. To engage the plunger, simply turn to line up with slot in body.
Available with or without locking element. All part numbers that end with a “P” do NOT have a locking element.
