RFLEX - Coupling Smart Joint Large Tolerance anchored

The RFLEX range of multi-material, wide tolerance flange sleeves guarantees sealing and tensile strength on all types of cast iron/steel pipes and PVC/PE pipes from DN50 to DN300 PN6 to PN16.

Very quick and easy to install, RFLEX allows independent adjustment of the locking and sealing mechanisms. 

The independently adjustable C40 hardened steel pads ensure locking. The gap left between the screw and the pad guarantees optimal positioning of the pad on the pipe surface when tightening. The specific shape of the teeth allows for clamping, ensuring high tear resistance. The pad can be mounted and removed without damaging the coating. The possible angular deviation is ±4°.

A RILSAN®11-coated ductile iron retention and anti-disengagement ring at each end increases tear resistance by guiding the pads and preventing them from rotating. It promotes better sealing by preventing the tie rods from rotating during tightening. It also protects the pads from external contamination.

The stainless steel tie rods connect the two parts of the sleeve. They compress the seals to achieve a perfect seal. The EPDM seals are truncated cones, which ensures optimal positioning on the pipe while allowing a tolerance of up to 26 mm on the outside diameter.

The part is coated with RILSAN 11, a high-performance biological polyamide made from renewable castor beans. This coating offers an exceptional level of versatility, safety, durability, and resistance to permeation.
