Pipeline Technology developed the Standard MiniBag kit, which utilises an inflatable bag to form a gas-tight seal in the inlet pipe, allowing you to replace the ECV whilst the pipe is still live.
The kit is supplied with inflatable MiniBags ¾” - 1¼” and 1½” to 2”, colour coded for easy identification, includes all necessary lightweight adaptors to cover BSP or BS746 meter tap thread sizes ¾” to 2”.
These are also available to purchase as spares below.
