DEDICATED RESTRAINED FITTINGS
KLAMFLEX Dedicated Restrained Fittings are designed to resist pipe end pull-out as which are as a result of thrust forces caused by internal pressure in the pipe. These thrust forces will occur wherever there is a change in direction (Bend) or elevation. The Dedicated Restrained product is to be utilised in applications as part of the overall pipe fitting design arrangement.
These fittings boast restraining lugs that are individually screwed onto the pipe, thus forming the restrained connection. The Dedicated Restrained Fittings are manufactured from Ductile Iron, Gasket material is EPDM, complete with FBE coating. Coupling Sleeve lengths available in both standard Full Sleeves as well as Double Sleeves. Flange Adaptor Sleeve lengths available in both standard Half Sleeve as well as Full Sleeves.

Sizes (mm) are available for the following pipe diameters: (PN10 & PN16) (Pipe OD's to suit Ductile Iron, Steel, HDPE, PVC Pipe)
