About Us

Buffalo Seal and Gasket Company opened for business in January 2004, with three employees in an 8,000 square foot manufacturing facility located in Houston, Texas. Today, Buffalo Seal and Gasket has become an industry-recognized leader in the manufacture, cutting and fabrication of custom gaskets and a master distributor of O-rings, with 14 employees and a 22,000 square foot manufacturing and warehousing facility, still located in Houston, Texas. The experienced and knowledgeable staff at Buffalo Seal & Gasket has over 75 years’ combined experience in sales and service in a wide range of specialties including:

  • Welded Polytetrafluoroethylene Joints – for customers needing a solid Polytetrafluoroethylene gasket with an outer diameter (OD) that is greater than the width of the Polytetrafluoroethylene sheet that is being used. Buffalo Seal and Gasket can cut the material, and, using a proven in-house proprietary method, weld joints to fabricate a seamless Polytetrafluoroethylene gasket that will meet or exceed your specifications.

  • Gaskets – one of our prime specialties is custom cutting gaskets to client specifications.

Gaskets are cut from a broad range of materials, such as rubber, UHMW, graphite, non-asbestos sheet, and plant fiber, to name a few.
