Expansion Plugs with Bypass


Style G	Style J	Style K

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 G—For Style G, twist the easy-grip T-handle to expand the seal. They have a Schrader valve bypass. An internal spring holds the valve shut until you depress the pin, giving you control over air flow.

Style J—For Style J, twist the wing nut to expand the seal. They have a Schrader valve bypass. An internal spring holds the valve shut until you depress the pin, giving you control over air flow.

Style K—For Style K, twist the wing nut to expand the seal. They have a Schrader valve bypass. An internal spring holds the valve shut until you depress the pin, giving you control over air flow.

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.
