The QTP QTEC 3-inch weld‑on 3‑bolt flange is a weld‑on flange sized for 3in pipe with a three‑bolt connection. Designed for fabrication use, it creates a welded mounting point to accept bolt‑on valves, cover plates or mating flanges. Install it when you need a permanent flange interface for QTEC cutout components during custom exhaust builds or repairs.
