Proco Series RC-221 Concentric Reducer — Rubber Expansion Joints

The Proco Series RC-221 Rubber Expansion Joints are designed to provide unequal diameter connections of piping and/or operating equipment. Excellent for absorption of pipe movement/stress, mechanical vibration, noise reduction, compensating for alignment offsets, eliminating electrolysis, and start-up/surge forces.

Vibrations originating from mechanical equipment are absorbed by the Proco Series RC-221. When installed ahead and after equipment to maximize vibration transmission reduction, piping sections should be anchored to isolate the equipment, allowing it to move freely on its vibration mounting.
