Product Spotlight:

Our line of Press-Thru (trade marked) spring and ball plungers have the same dimensions, spring pressures, and materials as our standard press fit product line.
Press-Thru™ Spring and Ball Plungers

Our line of Press-Thru™ spring and ball plungers have the same dimensions, spring pressures, and materials as our standard press fit product line. They are designed without the flange on the nose end to allow for the insertion of the plunger from top or bottom, front or back. Simply press the body through the hole until the plunger is flush with the surface. The body is slightly over sized to fit firmly into the hole. Please contact us for a free sample, or if you need any technical information.

Stainless Steel Short Lengths with Light Spring Pressures
Product Information

Stainless Steel Short Lengths with Light Spring Pressures

All stainless steel parts are made of 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.

To prevent possible spring damage, use of a Northwestern Wrench is recommended when installing from plunger end.
