Insulating Couplings

Walker Engineering’s insulating pipe couplings are specifically designed for connecting feeder pipe to pump houses, circulating plants and other above ground equipment requiring isolation from the feeder.

The coupling has two socket weld flanges with a G-10 insulating spacer and galvanized hardware spacers. The flanges have O-ring grooves for sealing and employ viton O-rings. Two spare O-rings are supplied with every coupling.

Walker’s couplings are available from 2″ to 6″ pipe sizes. Green signifies low pressure while orange signifies high pressure.
