Our socketed underground pipe from FloPlast incorporates the latest blown end technology. The easy fit rubber seal is held in place by a circular plastic insert allowing a retention of the seal in transit and a perfect connection for jointing.

All push fit underground fittings have a captive seal and snap cap which are designed to be user-friendly with no sharp edges, and with space restrictions in mind, allow for an easy fit connection. The seal is double ribbed and the sockets incorporate a recessed area to provide space for the rubber to locate as the pipe is inserted, forming a high capacity pressure point.
