Expansion Joints

Manage thermal expansion and contraction in vertical drain, waste, vent (DWV), and rainwater conductor systems with VANRON’s one-piece expansion joints. Designed to absorb linear movement in PVC, ABS, or cast iron pipes, our expansion couplings help eliminate the need for costly expansion loops or offsets often used to accommodate pipe growth.

What this means for your installation？

  • No sliding parts to malfunction → Zero risk of jamming or seizing over time

  • No freeze-related failures → Performs reliably in outdoor or unheated risers

  • No leaking at the connection → Internal positioning stops ensure perfect alignment every time

  • No maintenance required → Install it and forget it – no lubrication, adjustment, or replacement cycles

Result: A vertical pipe expansion solution that outlasts the building itself.
