Hand Retractable Plungers — Threaded Adapter* — Locking

Threaded Adapter drawing1

Threaded Adapter drawing2
Threaded Adapter
Zinc Plated Steel or Stainless Steel

The new threaded adapter is designed to accept any internally threaded knob or handle.

Available with or without locking element. To order without locking element, add a "P" to the end of the part number.

The nylon locking element holds the plunger body securely in place without the need for lock nuts or other devices. We recommend a 90° countersink 1/32" larger than the major diameter of the mating thread to prevent damaging the element.

Plunger can be with drawn completely into the body and locked in a fully retracted position. To engage the plunger, simply turn the end knob to line up with the slot in the body.

Plunger nose has a chamfered end to assure easy alignment.
