Packing Seal Tape
For use in valves and pumps, this thin, flexible tape is made from high-purity graphite with no fibers or binders that could contaminate your process line. Graphite is self-lubricating, plus it provides outstanding performance over a wide temperature range.
Adhesive-back tape stays in place during installation.

High-Temperature Graphite Pipe Gaskets
Able to withstand temperatures up 750° F, these graphite gaskets have a stainless steel insert for strength to handle pressure up to 1,000 psi. 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. All gasket specifications are sized to meet ANSI standards. Gaskets for ANSI Class 150 flanges are compatible with low-pressure pipe flanges. Gaskets for ANSI Class 300 flanges are compatible with medium-pressure pipe flanges.

High-Temperature Graphite Pipe Gaskets with Bolt Holes
Able to withstand temperatures up to 750° F, these graphite gaskets have a stainless steel insert for strength to handle pressure up to 1,000 psi. Commonly called full-face gaskets, they cover the entire face of flat-surface pipe flanges and align with the bolt holes. All gasket specifications are sized to meet ANSI standards. Gaskets for ANSI Class 150 flanges are compatible with low-pressure pipe flanges. Gaskets for ANSI Class 300 flanges are compatible with medium-pressure pipe flanges.

High-Temperature High-Pressure Graphite Gasket Material
These sheets and discs can withstand temperatures up to 850° F and pressure up to 2,000 psi. Use them when a strong seal is required in boilers and furnaces. Cut with a utility knife.
Discs are graphite with stainless steel layers; this high-strength material is commonly known as Hochdruck.
Sheets are graphite; they offer excellent compression under moderate loads.

Made-to-Order High-Temperature Graphite Gaskets
When you need a unique shape or size graphite gasket, we will precision cut one for you using your DXF file. This material, also known as Hochdruck, is graphite with stainless steel layers for added strength in hot environments.
First select a thickness, then select a sheet size that’s large enough to accommodate your gasket. Finally, send us your DXF file. Depending on the size of your gasket, we’ll send you as many same-design gaskets as a sheet will yield, up to 20 gaskets for 12"×12" sheets, and up to 40 gaskets for 24"×24" sheets.
Thread Sealant Tape
Made of PTFE, this tape has a slippery surface that keeps threads from binding to make parts easy to assemble.
PTFE tape with graphite creates a better seal between threads than plain PTFE tape, which helps prevent fluid and gas leaks. The graphite attaches to the PTFE, so this tape does not emit harmful VOCs.
