The RFLEX range of large tolerance, multi-material, non-locking sleeves guarantees a watertight seal on all types of cast iron/steel pipes and PVC/PE pipes from DN350 to DN1200 PFA16.
The tie rods compress the seals to achieve a perfect seal. The seal is truncated conical, which ensures optimal positioning on the pipe while allowing a tolerance of up to 24 mm (DN>600) or 30 mm (DN<600) on the outside diameter.
The part is coated with RILSAN®11, a high-performance biological polyamide made from castor beans. This coating offers an exceptional level of versatility, safety, durability, and resistance to permeation.

Product description
1- Central body
Central part made of RILSAN®11-coated carbon steel. The tapered ends ensure uniform compression of the seals without creep.
2- Compression ring
RILSAN®11-coated carbon steel compression flange, which compresses the seal onto the pipe surface when the bolts are tightened.
3- Gasket
Truncated cone-shaped gasket that fits perfectly between the connector body and the pipe. It provides a complete seal and a tolerance of 24 or 30 mm on the pipe's OD.
4- Bolt holes
Round or square holes for housing the bolts.
5- Compression tie rods
Made of GEOMET-coated steel or stainless steel, they bring the two compression parts together and ensure the sleeve is sealed.
