Pipe Linestop Sizes and Options:

54-60inch LinestopsSizes and Bypass Options: 1/2” through 72” Line stopping capabilities.  Our equipment has optional by-pass capabilities through the machinery, which eliminate the need for additional bypass taps. IFT offers “Full size” built-in bypasses on machinery through 48” if flow concerns are an issue.

Folding head machinery is available for reduced entry, at a reduced cost and weight; with a reduced by-pass size as well. Numerous Linestop® machines can be used to isolate and by-pass a system. For example: 4 way tees allow a bypass to each leg without a separate bypass tap.
