Superior Quality, Superior Service.

PTFE Valve Seat

At Chicago Gasket Co, we are pioneers in fabricating fluoropolymer and PTFE products. With over 60 years of PTFE processing experience, customers from a broad range of industries trust us to meet their exact specifications, both with industry-leading accuracy and on-time delivery. In the project illustrated here, a customer in the industrial equipment industry needed a custom fabricated PTFE valve seat ring. In addition to precise tolerance requirements, this project required high production volumes and a blanket release. Being one of the customers’ most trusted suppliers; we were pleased to accept the contract.

Using a modified PTFE known as Dyneon TFM-1600 in billet form, we constructed this valve seat using our 3-axis CNC lathe. When completed, the part measured 2.003" ID x 2.520" ID x .326" thick. Tightest tolerances of ±0.005" were achieved, with overall quality ensured by comprehensive First Article Inspection (FAI), in process, and final inspections. Our customer was pleased with our results, and commissioned us to produce 100,000 of these valve seats. This job was completed in its entirety, including delivery to Wisconsin, within a timeframe of just 3 weeks. Every aspect of this project met and exceeded our customers’ expectations, from high quality machining to inventory management. They continue to return to us for many additional projects.
