- 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° (±3° for flange adaptors).
- Cost effective – FlexLock can provide significant cost savings compared to non-locking couplings with a harnessing system.
- Restrains pressure thrusts without thrust blocks at bends.
- Convert cut lengths of pipe into flanged pipes - allows use of pipe offcuts.
- Working Pressure of 16bar on water up to and including DN200 and 10bar for DN250 & DN300. For gas applications a working pressure of 6 bar can be achieved.
- The ability to provide angular deflection in ANY plane is a particular advantage - a harness assembly can provide angular deflection only in ONE plane.
