Stubby Plungers – Stainless Steel with Delrin® Nose

Delrin® Nose Stubby Plungers – Stainless Steel are compact threaded spring loaded devices for limited-space applications that require a non-marring, electrically insulating contact surface. The stainless steel body provides maximum protection against rust and corrosion while the Delrin® nose resists repeated impacts, moisture and solvents and withstands heat up to 190°F with a self-lubricating surface. Available in ANSI thread sizes 8-32 through 5/8-11 and metric M4 x 0.7 through M16 x 2.0 with standard or light end forces and optional thread lock.

Specify by:

Thread standard and size (ANSI or metric)
End force requirement (standard or light, initial and final)
Thread lock requirement
