Test plugs and pipe plugs for small pipes
Do you need to close off or pressure-test a small pipe safely? Our test plugs, also called pipe plugs, are mechanical plugs for the small diameter range. They are inserted into the line and tightened so that they sit firmly and tightly, ideal for briefly shutting off before maintenance, plumbing or testing work. We stock them in sizes 12, 19, 25 and 32 mm, suitable for the common plumbing and domestic installation lines. As a manufacturer based in Bad Abbach, we build them ourselves, Made in Germany.

What you need a test plug for
The test plug is the quick, inexpensive solution for sealing off a small line. Typical uses are shutting off before repair and plumbing work as well as pressure-testing small connection lines. By tightening it inside the pipe, the plug sits securely and withstands the applied pressure. For larger diameters or for pneumatic shut-offs, you will find the right products among our shut-off bladders and shut-off discs.
Sizes from 12 to 32 mm
Our test plugs cover the common small pipe diameters with 12, 19, 25 and 32 mm. What matters is the inner diameter of the line you want to close. If you are unsure which size fits, we are happy to advise you free of charge via our hotline.
