Liner End Sleeves

Liner end sleeves professionally finish off a lining job, by sealing the gap between the liner and the host pipe.

This protects the liner end from the effects of high pressure jetting and ensures that no debris can enter the gap causing further problems or pressures to the new liner in the future.

S1E Limited offers two sorts of liner end sleeve:  Quick-Lock and K-prema.  These are similar to the mechanical repair systems offered within those ranges, but are especially designed for this liner end sealing application.  More information on each system is below.

Quick-Lock Liner End Sleeve

  • The Quick-Lock Liner End Sleeve functions in the same way as the Quick Lock Point Repair System.
  • The EPDM rubber seal has been designed to accommodate all common liner wall thicknesses.

Our customers say

'We chose to use the K-Prema seals as we know they will seal the end of the liner and withstand the pressure test every time. The K-Prema seals were easy to fit and the whole job was plain sailing.'
