About Us

Gaddis, Inc. has been in the seal business for over 50 years. Our owner, Bob Gaddis, the son of the founder has been in this business for over 40 years. Gaddis, Inc. has been operating out of Hilton Head since 1992.

Currently, Gaddis has almost $800,000.00 of mechanical seal parts and packing in stock. Our excellent quality, inexpensive pricing, and product availability, provides many pump repair facilities with an alternative to the OEM and major mechanical seal manufacturers product without sacrificing performance.

The main focus of Gaddis, Inc. is Mechanical Seals. We provide quality new and replacement mechanical seals and similar parts for over 350 OEM’s pumps, grinders, and mixers used in a number of industries, at significant cost savings. Since 1961 we have created a large library with hundreds of Gaddis machine drawings that cross-reference the major mechanical seal and equipment manufacturer’s part, drawing, and/or bill of material numbers.

We can custom engineer a mechanical seal to fit almost any application. To date we have built specialty mechanical seals from 3mm or .181” to 32.312” shaft or spindle diameters, pressures from full vacuum to 2,000p.s.i.g.; temperatures -85 to + 700 deg. F and speeds up to 10,000 surface feet per minute depending on application

Not only does Gaddis, Inc. manufacture and design Mechanical Seals, but our facilities enable us to provide you with the option to repair/rebuild your old inventory. You can send us your old seals and our engineering department will examine them and give you a price on the option to repair/rebuild them as needed. While we have the old mechanical seals, our engineering staff can analyze your mechanical seals and give you some feedback for their failure. Just ask!
