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

Plungers may be ordered without the locking element. Plungers without an element are the same price, but are considered "Special" and cannot be returned.

  • Stainless Steel Body
  • Nose Stainless or Delrin-Heavy or Light Pressure
