Overview

The NSi Industries Galvanized Steel Reducing Washer (SKU: 1089-5) is a precision-engineered mechanical fastener designed to bridge connections between pipes, bolts, or mounting surfaces of differing diameters. Manufactured from high-quality galvanized steel, this washer provides superior corrosion resistance and long-term durability in industrial, construction, and structural applications. Its unique reducing design transitions from a 3.5-inch outer diameter to a 1.5-inch inner diameter, enabling seamless integration between components with mismatched sizing. This washer ensures a secure, vibration-resistant fit for professional installations where precise alignment and load distribution are critical. Common applications include plumbing systems, HVAC installations, structural steel assemblies, and machinery mounting where diameter transitions are required. The galvanized coating meets ASTM standards for corrosion protection, making it ideal for outdoor or high-moisture environments. Unlike standard flat washers, the reducing design eliminates the need for additional adapters, reducing installation time and potential failure points. Compatible with standard hardware sizes, this washer is a cost-effective solution for adapting 3.5-inch fittings to 1.5-inch bolts or pipes.
