Overview

The ABB STTB5-G PVC Coated Bulkhead Fitting is a precision-engineered solution for secure pipe connections through bulkheads in industrial, marine, and construction applications. Designed for 1-1/2 inch pipe size with 1-1/2 - 11-1/2 NPT thread, this fitting ensures leak-proof performance with a nitrile rubber (Buna-N) sealing ring and thermoplastic insulated throat. The exterior features a minimum 0.040-inch (40 mil) PVC coating bonded to a zinc body, providing superior corrosion resistance and durability in harsh environments. With a height of 1.81 inches, diameter of 2.75 inches, and across flats of 2.13 inches, the STTB5-G meets ANSI C80.1-1994 standards. Its gray PVC coating resists abrasion, UV exposure, and chemical degradation, making it ideal for outdoor and corrosive installations. The fitting’s robust construction includes a threaded locknut (included) for secure bulkhead mounting, preventing loosening under vibration or thermal cycling. Compatible with rigid and intermediate metal conduit systems, the STTB5-G is manufactured in the US by ABB Installation Products, a trusted name in industrial electrical and mechanical solutions. Standard color is dark gray; custom colors are available upon request. Trust ABB for reliable, long-lasting bulkhead fittings that protect system integrity in critical applications.
