Redflex is the only line of NSF 61 Certified expansion joints designed to relieve piping stress, compensate for movement, reduce noise and isolate vibration.
The rugged PTFE core extends through the entire length of the joint to the face of the flange. The PTFE is backed by a fabricated rubber body reinforced with high-strength synthetic fabric and steel wire. The cover material is selected to suit service characteristics and has the option to be coated with special paint to resist weathering, ozone or acid fumes. NSF 61 Certified expansion joints are available with single, double, triple or wide arches.
