Gasket Resources Inc. excels at providing fast, precise results in lathe cutting. Utilizing CNC lathes, we work with billets of Durlon® 9000 PTFE with outside diameters of up to 24 inches, and a maximum gasket size of 23 ⅞ inches. Tolerances are typically held at +/- .010 for inner and outer diameters, and +/- .002 for thickness.
Advantages to Lathe Cutting
Lathe cutting a gasket material offers a number of inherent advantages. Customers save money with our proprietary billet molding process & lathe cutting, which causes less wasted material. Lathe cutting our cylindrical Durlon® 9000 billets eliminates the center waste that comes with cutting from sheet; as PTFE is sold by the pound, this is an incredibly important factor. By lathe cutting, we reduce our customers’ unwanted material, which can render up to 30% in savings. Also, for every gasket we lathe cut, we have traceability—all the way back to the raw materials and the date it was manufactured. Finally, Gasket Resources Inc. is the only company offering branded PTFE material in billet form. Our competitors cannot offer the same functionality.
