About this product
Tri-lug knock union for connecting Roofer's hot pipe. It does not require a pipe wrench for connection of pipe or tubing. Because of pricing, these are usually saved and installed on tubing that can be purchased without unions, but with the extra heavy nipples that Roofmaster furnishes with its Lite Wall Tubing.
