The FlexLock system provides a self-anchoring method of joining ductile iron
or steel pipes and offers a cost effective, quick and simple alternative to
traditional anchoring systems such as site welding, harnessing or thrust
blocks.


Gaskets have embedded stainless steel teeth that grip the outer surface of
the pipe, yet still allow for angular deflection of pipes in service. This
prevents pipes from separating under pressure loads, making FlexLock ideal for
above ground and buried applications, soft ground conditions or temporary pipe
work.


FlexLock permits angular deflection between pipes, allowing for normal
pipeline movement such as ground settlement. Long radius curves can also be
accommodated, reducing the need for special fittings. FlexLock couplings allow
for a total angular deflection of ±6 degrees.



  • Supplied as standard with EPDM gaskets for water applications to EN 681
  • Metal components are coated with Rilsan Nylon 11 which is WRAS approved
    for use with potable water. The nuts and bolts are Sheraplex coated to WIS
    4-52-03
  • Working Pressure of 16bar on water up to and including DN200 and 10bar for
    DN250 & DN300
  • Can provide significant cost savings compared to non-locking couplings
    with a harnessing system
  • Ability to provide angular deflection in any plane

Due to the weight restrictions, items sized 300mm and above may incur an
additional carriage charge.
