Silicone Caps

As low as $19.99

Silicone caps mask threaded & non-threaded studs and tube ends during high-temp (600F / 315C) applications, like e-coating & powder coating.

Choose the Stud Size to Mask below that most closely matches the diameter of the stud/bolt/tube you are wanting to cap.

If you know the Part Number you want to order, you can type it into the search bar at the top of the page to easily find it 

A cap's inside diameter typically needs to be undersized by around .030" in order to effectively mask a stud, tube, or bolt. We used this logic for the Stud Size to Mask (in) dropdown above.

Example: If the tube's outside diameter (OD) you're masking is 0.2", then the cap that will work best would be 49-0000172-01000 because its Inside Diameter is 0.172"
