3/8" Rubber Plugs & Hole Stoppers

(3 products)

3 sizesfrom $0.38ships from Elgin, SCbulk pricing from 50+

This page gathers the plugs we make for 3/8" holes. Push-in bumper plugs grip a panel by a groove under the head, so they work as a hole cover and a soft stop at the same time. Line-sealing stoppers are plain rubber stems that press into a 3/8" bore, tube or port to block it. We have also included an 11/32" stem stopper, a little smaller than 3/8", for holes that measure undersize or where you want an easier push.

Measuring tips. A 3/8" hole is 0.375". Check it with calipers or a drill bit used as a gauge: if a 3/8" bit slides in with no play, a 3/8" stem will be snug. For a push-in plug, also measure the thickness of the panel and match it to the groove listed on the product. Note that some of our flat bumper feet have a 3/8" wide head but fit a smaller hole; the size in the product name before the "x" is the head, and the "Fits" size is the hole.
