Buna-N Rubber Sheet 1/4 X 6 X 6 - 40A Durometer Oil Resistant Gasket Material

About This Product

DIYers and mechanics, this Buna-N rubber sheet is seriously handy stuff to have in your workshop! Measuring 6x6 inches with a 1/4 inch thickness and 40A durometer, it's perfect for making custom gaskets, seals, pads, or any rubber component you need. Buna-N (also called nitrile rubber) is awesome because it resists oils, greases, fuels, and petroleum products really well, plus it handles water and mild chemicals without breaking down. The physical properties are impressive - 1000 psi tensile strength, 350% elongation, 20 N/mm tear strength - so it's tough and durable for demanding applications. Temperature range is from -30° to 250°F, which covers most automotive and industrial uses. I've used pieces to make gaskets for engine covers, fuel line connectors, and even as vibration dampeners for machinery. The black color and smooth texture look professional, and it cuts cleanly with a utility knife or scissors. It meets ASTM D2000 standards, so you know the quality is consistent. Whether you're repairing equipment, building projects, or just need reliable rubber material on hand, this Buna-N sheet delivers performance and value. It's become one of those workshop essentials I always keep stocked because you never know when you'll need to make a custom seal or gasket!
