Product family

Couplings and assembling

The RFLEX range of multi-material, wide tolerance flange sleeves guarantees tightness and tensile strength on all types of cast iron/steel pipes and PVC/PE pipes from DN50 to DN250 PFA25.

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

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

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

The 8.8 corrosion-resistant steel tie rods connect the flange to the fitting. They compress the gasket to achieve a perfect seal. The EPDM gasket is truncated conical, 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.

Features

Product description

1- Central body

Central part made of GS cast iron coated with RILSAN®11. The conical ends ensure uniform compression of the seals without creep.

2- Seal
Truncated cone-shaped seal that fits perfectly between the connector body and the pipe.

3- Locking insert

Made of GEOMET-coated C40 hardened steel, it locks the pipe in place with high tear resistance thanks to the special profile of the teeth. The clearance between the screw and the insert ensures optimal positioning of the insert on the pipe surface when tightening. The insert can be installed and removed without damaging the coating.

4- Sealing tie rod

Made of 8.8 steel with anti-corrosion treatment, it brings the flange and the connector closer together to compress the seal and ensure the adapter is watertight.
