One of the top-five world wide manufacturers

of instrumentation fittings and valves, SSP is

the only 100% made-in-the-USA-player in

this industry. Founded in 1926 as a manufacturer

of screw machine products, SSP introduced

instrumentation brands Duolok, Unilok, Griplok and TruFit in the 1990's.

During that same decade SSP earned its ISO 9001 certification. In 2000 SSP made its way into the instrumentation valve market by acquiring Flolok valve line. The most recent addition is SSP Valves, which are functionally and dimensionally indistinguishable from industry standard designs.

SSP is a vertically integrated manufacturer that has embraced Kaizen methodology and Six Sigma tools

to create a Lean manufacturing environment. All manufacturing is performed in Twinsburg, Ohio. SSP

uses these investments to focus on the installer and end users of its products through a network of distributors.
