The RFLEX range of multi-material, wide tolerance flange adapters guarantees a tight seal and tensile strength on all types of cast iron/steel pipes and PVC/PE pipes from DN350 to DN1200 PN10 to PN16.


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.

Features

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 that compresses the gasket against the pipe surface when the bolts are tightened.

3- Gasket
Truncated cone-shaped gasket that fits perfectly between the fitting 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 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.

6- Connection flange

Made of RILSAN®11 coated carbon steel. EN1092.
