Expansion Plugs with Bypass


Style E	Style F

Use the bypass tube on these plugs to add air, water, and other fluid to your pipeline or to relieve pressure while testing. The seal expands to temporarily close off pipe openings.

Style E—For Style E, twist the wing nut to expand the seal. They have a barbed bypass for quick connections to tubing.

Style F—For Style F, twist the easy-grip T-handle to expand the seal. They have a barbed bypass for quick connections to tubing.

Maximum Air Back Pressure—Maximum air back pressure is the amount of pressure a plug can withstand without moving.

Maximum Water Back Pressure—Maximum water back pressure refers to the pressure resulting from the height of the water above the plug.
