Laser Cut Cork Gasket, the ultimate sealer

SendCutSend’s gasket grade sheet cork is manufactured with one clear goal in mind: creating a seal that you can trust. Rubber-bonded with oil, solvent, and petrol resistances, you can trust your cork gaskets, seals, and panels to be leak-free and durable. It even seals well at low flange pressures and high temperatures.

Used in a variety of applications

In addition to its many automotive, plumbing, and machining applications, sheet cork can also be used in decorative and aesthetic functional projects. From laser cut cork bulletin boards to coasters to home organization tools, sheet cork deserves a place in your next project.
