Founded in 1971, G.S.F. Plastics Corporation began their operations in the thermoplastic manufacturing of PTFE molded tubes and machine parts. In the early 80's, products manufactured of PEEK™ were added, with tubes and solid rods produced in both the compression and injection molded process. Today, our customers continue to rely on G.S.F. to provide the highest quality products with the highest physical properties.

We are experienced manufacturers of custom, precision engineered thermoplastic stock shapes and machine finished parts. For 40 years we have been fabricating parts (back up rings, seats, and seals) from engineering thermoplastic products such as PTFE, PEEK, NYLON, DELRIN, etc.
