About us

GSAI Manufacturing Group was established in 1992 when several entrepreneurs decided to put together a firm specializing in producing economical, high-quality fittings for a practical plumbing market. The firm began with a little over 30 products and has since expanded to over 300 items.

Today, GSAI owns manufacturing plants, offices, and warehouses/distribution centers, and has excellent relationships with sales representatives, key industry leaders, and suppliers working together to deliver a high-value and durable line of copper fittings to suppliers, retailers and contractors.

GSAI manufactures its copper fittings under a strict inspection system, pressure testing and quality control arrangement to be used in America's stringent plumbing, heating, air conditioning and refrigeration installations. Particular care is taken with the dimensions and machining to insure a clean and perfect solder joint.

Our pressure fittings follow either the world recognized ASME/ANSI B16.22 or ANSI B16.18 standards. Our DWV fittings follow the ASME B16.29 and ASME/ANSI B16.23 standards.

Today, GSAI takes great pride in our strong attention to quality, value, dependability, and the prompt service that we offer our customers.
