STENFLEX® Rubber expansion Joints are made of high quality rubber that enable better compensating and damping material properties. Excessive forces are deflected by STENFLEX® rubber joints before they're passed to adjacent components therefore ensuring long service life and operational reliablity.
Damp oscillation, noise and vibration
Compensate motion
Compensate expansion caused by differences in temperature
Reduce tension
Compensate ground and foundation settling
Compensate imprecise assembly
Serve as assembly and disassembly aids
Provide an elastic wall seal for penetration assemblies
Compensate pipeline movements aboard ships
Bellow Meterials
EPDM, CIIR (Butyl), NBR (Perbunan), CR (Neoprene)
