Expert Verdict — Reviewed by the SuperArbor Pro Desk
Keep a spare union on the truck; a worn union is one of the most common hot pitch line failure points. Match the union size exactly to the pipe diameter and inspect threads for pitch buildup before reassembly. Replace rather than over-tighten a leaking union.
Service hot pipe unions only after the system has cooled and pitch pressure is relieved; hot pitch can cause severe burns.
Add the Roofmaster 1-1/2 in. Stockham compatible equal union to keep your hot pitch lines leak-free.
