Overview

The ABB STTTB2-G PVC Coated Through-Bulkhead Fitting is a precision-engineered industrial component designed for reliable sealing and insulation in demanding bulkhead applications. Manufactured by ABB Installation Products, a global leader in electrical and installation solutions, this fitting combines robust construction with advanced material science to deliver unmatched performance in harsh environments. The 3/4-inch pipe size (21 metric) with 3/4-14 threading ensures a secure, leak-resistant connection, making it ideal for installations where structural integrity and fluid containment are critical. Key features of the STTTB2-G include a durable PVC coating that provides exceptional corrosion resistance and electrical insulation, protecting against moisture, chemicals, and abrasion. The thermoplastic insulated throat enhances thermal stability, preventing heat transfer and maintaining system efficiency in high-temperature applications. A nitrile rubber (Buna-N) sealing ring delivers a tight, vibration-resistant seal, ensuring long-term reliability even under dynamic loads or pressure fluctuations. The compact design (1.47-inch height, 1.69-inch diameter, and 1.25-inch across flats) makes it particularly suitable for space-constrained bulkhead installations, where traditional fittings may not fit. This fitting is engineered for versatility across multiple industries, including electrical, plumbing, HVAC, and industrial machinery. Its gray color coding simplifies identification in complex systems, while the Buna-N seal ensures compatibility with a wide range of fluids, including oils, water, and mild chemicals. The ABB STTTB2-G is a cost-effective solution for professionals seeking a high-performance bulkhead fitting that meets rigorous industry standards without compromising on durability or safety. Trust ABB Installation Products for components that combine innovation with reliability in every application.
