Reducing Expansion Joints

Red Valve Company’s Concentric & Eccentric Reducers and Reducing Expansion Joints are designed to allows simple connection of different sized pipes. Reducing Expansion Joints also provide all of the benefits of a Redflex Expansion Joint. Reducers can be used as pipe reducers or increasers, expansion joints, flexible connectors and vibration eliminators.

Redflex Reducers were designed to replace metal reducers in the pipeline. Standard reducers have a smooth-walled reduction from flange to flange. Reducing Expansion Joints are available in single, double, and triple arches, in either open or filled models. The multiple arches are used in applications where expansion or contraction will occur.
