Snap It® Engineered Tube Plugs
Tapered plugs aren't pressure rated because results depend on how they're installed. For a rated, repeatable seal with no welding, choose Snap It®. It installs hydraulically in under 60 seconds.
Metal Tapered Tube Plug FAQ
What does the "X" in the part number stand for?
It's a placeholder for the material. Replace it with your material code, such as S for stainless steel or C for carbon steel.
What if I need a size that isn't on the chart?
We make all of our plugs in-house and aren't limited by size. Send us the A, B, and L dimensions and we'll make it. We can produce more than 5,000 plugs a day.
What if I only have the inside diameter of my tube?
Call us with the ID and we'll recommend the right size.
What do I need to install these plugs?
Tapered plugs are installed with a hammer. Puncture the tube first with a tube cutter so pressure can't build up behind the plug over time.
Can I seal weld the plugs in place?
Yes. Seal welding is a common way to get a stronger seal.
Are your tapered plugs pressure rated?
No. Tapered plug installation is uncontrolled and inconsistent, so holding pressure depends on installation methods and best practices. For a rated plug, use Snap It® tube plugs.
What if the material I need isn't listed?
We make plugs in more than 20 materials and have likely worked with yours. We'll make custom plugs on request, 24/7/365.
