THE MULTI-SIZE FLOW-THRUS™ are built with the same patented designs as our multi size Domehead™ plugs.
The Flow-Thru™ plug goes one step further by offering a large bypass within the pipe plug. The bypasses are ideal for doing a water test or sewer bypass. LANSAS Flow-Thru™ plugs are available with standard bypasses up to 8″ NPT. 12″ threaded connections and larger flanged connections can be special ordered.
As with any LANSAS plug, the multi-size Flow-Thru’s™ can be manufactured with nitrile or neoprene rubber and stainless steel components for use in chemical and petroleum applications.
Test caps are available to convert your Flow-Thru™ pipe plugs over to use in air testing applications. A PVC cap is supplied with each plug with up to a 6″ NPT bypass.
