Inox flanged sleeve - 22 R1 1/2" 1609090004

Flange Sleeve Made of Stainless Steel 316L

Designed for use with press-fit systems, the flange sleeve made of stainless steel 316L (1.4404) ensures corrosion resistance even in aggressive environments – such as in district heating, water supply, or industrial installations where chlorides or moisture are present. The material is identical for both the flange and the internal connection part – eliminating the risk of galvanic corrosion when assembling with other components.

The internal seal made of EPDM (ethylene-propylene-diene rubber) ensures tightness at pressures up to 16 bar and temperatures ranging from -40°C to +120°C. Its flexibility allows compensation of minor axial deviations during pressing while maintaining the seal even after prolonged operation.

The LBP (Leak Before Break) controlled leak function acts as an additional safety mechanism: if the seal is damaged, water will begin to escape in a visible and controlled manner – not suddenly, and not under high pressure. This allows the installer to detect the issue before system failure and enables the user to avoid serious consequences of leaks.

The press-fit coupling connection is compatible with standard pressing tools for pipes with an outer diameter of 22 mm (DN 20). The working length of the seal is 7 mm, ensuring stable and uniform pressing without the risk of twisting or improper alignment. The total length of the sleeve is 28 mm – sufficient to ensure proper pipe insertion depth and even distribution of pressing force.

No additional seals or pastes are required. Installation is simple: the pipe is inserted into the sleeve and then pressed in one motion with the tool – the entire assembly becomes a unified, tight, and durable unit.

The sleeve does not require welding, threading, or mechanical assembly. It functions solely as an intermediate component in the press-fit system – but thanks to its material and design, it is one of the most reliable points in the entire installation.
