Flanged Rubber Expansion Joint DN25-PN16 Butyl (CIIR)

This DN 25 EPDM expansion joint, PN 16, is a flexible connector designed to absorb axial, lateral, and angular movements in pipelines, compensating for thermal expansion, misalignment, and vibration. It is commonly used in water supply systems, heating installations, and industrial applications to ensure system integrity and reduce stress on connected components. It is made from EPDM bellows and galvanized steel flanges. Suitable for temperatures of up to 90°C, from 60°C the operating pressure reduces. The maximum operating pressure is 16 bar up to +60 °C, 11 bar at +80 °C, and 6 bar at +90 °C, with a burst pressure of 48 bar. For systems with pressure surges or intermittent loads, the maximum operating pressure should be reduced by 30% to prevent premature wear.

Pros:

• Suitable for drinking water applications due to butyl bellows (CIIR)
• Approved by KTW for drinking water
• Swiveling steel flanges with self-sealing rubber flange collars ensure secure and leak-proof connection
• Suitable for temperatures of up to 90°C
• Suitable for vacuum, pressures ranging from -1 to 16 bar
• Axial compression (20 mm), axial extension (10 mm), lateral offset (10 mm), angular deviation (25 degrees)
