This portable and easy to use pressure pot for joint injection, designed for 4”-12” joint repairs.

Mainspray is a two-component anaerobic polymeric compound formulated for sealing leaking spigot and socket joints on cast iron and steel gas mains, conforming to GIS/LC12 specification. We have developed a 1ltr pressure pot to directly inject Mainspray under pressure to reinvigorate and seal joints.

Leaking joints can now be treated without leaving the surface. This can have a big impact where a series of joints needs to be treated at frequent intervals along a main road. Long reach tooling allows the back of a socket to be drilled and tapped to accept a standard brass injection nipple. The repair product is injected into the joint using long delivery tubes and our 3litre or 1litre pressure pot.

The 1ltr and 3ltr Mainspray pressure pot are designed for 3bar maximum working pressure. Both pots work in conjunction with the back of socket long handled tooling for above ground working.
