Expansion Plugs

Expansion Plugs with Bypass

Use the bypass tube on these plugs to add air, water, and other fluid to your pipeline or to relieve pressure while testing.

Inflatable Plugs

Fill these plugs with air or water to create a secure seal inside pipe that is not perfectly round.

Deep-Reach Expansion Plugs

Unlike most plugs that seal pipes at the opening, these plugs create a seal deeper within the pipe.

Expansion Plugs for Tubing

These plugs are designed for metal and rigid plastic tubing.

Other Test Plug Pipe Fittings

Pressure Test Fittings

When you need to test pressure, these fittings create a temporary connection point so you can attach test gauges and other test equipment.

Plugs

Protect a variety of shapes and sizes of unthreaded and threaded components.
