Die Cut Gaskets

We offer most major die cut gaskets and gasket material brands.

Our slogan is: There is nothing more expensive than a cheap seal and it truly applies to gaskets.

Too often the gasket material that was chosen based on prices the one that’s leaking on your floor. Our roots are in sheet gasket materials. Our founder comes from a background with Durlon and Garlock, and has toured most gasket manufacturing operations in the United States and a few in Europe. This guide is based on the best sealing practices seen and developed over the past 40 years in the industry.

Die Cut Gaskets and Material Options

Non-Asbestos Gaskets

Non-Asbestos Gaskets – Can be cut using 4 methods.

1) Hand-Cut Gaskets

2) Die Cut Gaskets

3) Water Jet Gaskets

4) CNC Dieless Cutting Gaskets

Non-Asbestos Material

We cut Non-Asbestos Gaskets from all the major manufacturer’s materials including, Durlon, Garlock, Klinger, Thermoseal, Tedit, FMI, Johns Manville, Frenzelit, Utex, etc.

Expanded PTFE is an FDA approved sealing material. It’s a very clean material originally used in the semiconductor industry. It’s also a very easy material to cut. A razor blade cut’s it easily so it’s handy to have some ePTFE gasket material on hand.  We, of course, are happy to cut your gaskets for you.  ePTFE cuts accurately on our laser, and just as well on our knife-edge CNC dieless gasket cutter.

Expanded PTFE seals quicker, with less torque, is easier to cut, better, with reduced cold flow. Any form of PTFE gasket sheet is great for making gaskets intended for chemical applications, food, and beverage gaskets. It is capable can serve in temperatures up to 600°F Peaks. 

We cut PTFE Gaskets from sheet to your required dimensions.

PTFE is an abbreviation for PolyTetraFluoroEthylene, which is a synthetic fluoropolymer of Tetrafluoroethylene that has endless applications. PTFE is best known as Teflon® which is a trademark of Chemours (formerly Dupont).

PTFE has a low coefficient of friction, outstanding insulation capabilities, & is chemically inactive to most substances. It has a reputation for its anti-stick properties & its endurance in high heat applications.

PTFE is available in several different forms. Step one is determining what type of PTFE gasket is needed for the given application. The most common form is Virgin PTFE however in recent years Biaxial PTFE and Expanded PTFE has been developed. 

Any of the above forms of PTFE gasket sheet is great for making gaskets intended for chemical applications, & can serve in temperatures up to 450°F continuous. 

Durlon 9000 – Sichem Sheet

We offer both a skived filled PTFE and biaxial PTFE

Sichem is a HS10 Dupont process biaxial oriented PTFE sheet gasket material. Produced with silica, barium sulfate, or glass microspheres. 

Durlon 9000 is manufactured by Gasket Resources in North America.  Conforms to FDA requirements. And has achieved numerous certifications: WRAS (Water Regulations Advisory Scheme) Approved Material, USP Class VI, FDA and (EC) 1935/2004 & EU (10/2011) compliant, BAM oxygen service, TA-luft (VDI Guideline 2440), ABS-PDA & Pamphlet 95, the chlorine institute, DNV-GL. And has passed the API 6FA fire test.

 The filler used with the PTFE in both Durlon and SiChem products increases the physical properties of the PTFE, and reduces cold flow, resulting in exceptional gasket materials.

Flexible Graphite Gaskets

Graphite Gaskets – Todays biggest sealing solution is flexible graphite. It’s compatible with a wider range of service applications than any other gasket material. It also seals better than any other material.  Need to seal helium? Flexible graphite to the rescue! Using our in house CNC dieless gasket cutter we can produce whatever we can draw. We can cut our own AS&P brand or any of the following: Grafoil, Durlon,  SGL, Garlock, Klinger, Thermoseal, Tedit, SiChem, Johns Manville, Utex,  etc.

Application Range

Graphite gaskets are unique in that they have a 0-14 ph Range.  Temperature capabilities depend on the presence of oxygen.

No oxygen = 5,400 F max temperature

Breathable Air = 850 F max temperature

Steam (reduced oxygen) = 1200 F Max Temperature

Frequently Asked Questions


No Branded brands are always superior.  There are plenty of bargain unbranded gasket materials out there. It never makes sense to skimp on the most vulnerable part of your equipment.


The closest thing to a universal material would be Flexible Graphite, or Expanded PTFE simply because they both have a 0-14ph range.  So they are both compatible with most materials.  Sulfuric and Nucleic acids are a problem for graphite. In PTFE or Teflon, Fluorine based chemicals can be the problem.


The first thing to consider is, does the manufacturer brand their product?  In today’s market, there is a lot of foreign-made inferior sheets that are usually unbranded. Most unbranded sheets were sold to the gasket cutter based on price.


The method of cutting depends on the quantity being cut and the tolerances required.  Old fashion clicker presses are still the most efficient way to cut high volumes. A knife edge CNC allows us to cut without requiring the cost and delay of having a die made.  We also cut with a laser for ideal materials like PTFE.
