High-Temperature Oil-Resistant Carbon/Buna-N Pipe Gaskets

These blended carbon/Buna-N rubber gaskets are unaffected by oil and temperatures up to 650° F. Also known as ring gaskets, use them with raised-surface pipe flanges; they fit the surface inside the bolt holes and do not interfere with the bolt connection. Gaskets are compatible with low-pressure pipe flanges; all gasket specifications are sized to meet ANSI standards.

High-Temperature Oil-Resistant Carbon/Buna-N Pipe Gaskets with Bolt Holes

Carbon is blended with Buna-N rubber for gaskets that are unaffected by oil and temperatures up to 650° F. Commonly called full-face gaskets, they cover the entire face of flat-surface pipe flanges and align with the bolt holes. Gaskets are compatible with low-pressure pipe flanges; all gasket specifications are sized to meet ANSI standards.

Ultra-Conductive Graphene Sheets

This highly conductive graphene material is often used in electronic devices, such as cell phones, laptop computers, digital cameras, and LEDs. It can be folded without tearing or damaging the sheet and can be cut into smaller pieces with scissors. Thickness, width, and length tolerances are not rated.

Ultra-Conductive Graphene on Copper Foil

Grown by chemical vapor deposition (CVD) on copper foil, this highly conductive graphene material can be transferred using chemical methods such as polymer-supported metal etching, and mechanical methods such as thermal release tape and direct transfer. This graphene foil is 200 times stronger than steel by weight and is also flexible. It comes taped to the corners of a plastic container in a double vacuum-sealed bag to maintain shelf life. Do not remove the packaging until ready to use. Gently peel the tape or cut the corners of the foil to release. Use rolling blades or precision knives to cut the foil.
