Overview

The ABB CB1/2-B PVC Coated Clamp-Back Spacer is a precision-engineered pipe support solution designed for secure and corrosion-resistant installations in industrial, commercial, and HVAC applications. Manufactured by ABB Installation Products, this spacer is specifically engineered for 1/2-inch (16 metric) pipes, ensuring optimal fit and performance. Constructed from durable malleable iron, the CB1/2-B features a nominal 0.015-inch (15 mil) PVC coating that provides superior corrosion resistance, extending service life in harsh environments such as chemical plants, food processing facilities, and outdoor installations. The light blue finish enhances visibility during installation and maintenance, reducing the risk of errors in complex piping systems. Compatible with standard one-hole pipe straps, the CB1/2-B spacer creates essential air gap spacing between the pipe and mounting surface, preventing moisture buildup and promoting airflow for improved thermal management. This design is critical in applications where condensation or corrosion could compromise system integrity. The spacer’s robust construction meets stringent industry standards, including UL/CSA listings for safety and reliability. Ideal for use in HVAC systems, plumbing networks, and mechanical installations, the CB1/2-B spacer simplifies assembly while maintaining a stable, vibration-resistant connection. Its compatibility with ABB’s PVC-coated pipe straps (available in one-hole malleable iron or two-hole stamped steel variants) ensures seamless integration into existing systems. The product is part of ABB’s Ocal® corrosion-resistant conduit systems, a trusted line of components designed to withstand corrosive environments. Key specifications include: - Pipe size compatibility: 1/2-inch (16 metric) - Material: Malleable iron with 0.015-inch (15 mil) PVC coating - Color: Light blue (standard), with gray and white options available - UNSPSC code: 31161816 - Compatibility: One-hole pipe straps (e.g., 1HMS1/2- series) The CB1/2-B spacer is a cost-effective, long-term solution for professionals seeking reliable pipe support without compromising on durability or performance.
