EXPANSION JOINTS In a small amount of space, expansion joints are able to absorb relatively large degrees of motion caused by pipe expansion and contraction. Expansion joints are used in many industries as flexible connections in pressure and vacuum lines. Our Expansion Joints listed are available in all standard pipe sizes from 1 inch to 72 inch I.D.

Many items are available for same day or factory direct shipment.
