Quality Gasket Material for Industry

We offer most major brands of gasket material and some you may have not heard of. All of our selected lines are top shelf quality, nothing gets through our door without a quality check.

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 price is 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 last 40 years in the industry.

Flexible Graphite Sheet

Flexible Graphite Gaskets – Once considered as a specialty gasket material for extreme temperature & chemical services, Flexible Graphite Sheet Gasket material can now be found in more typical applications. Flexible graphite has emerged as an affordable option for the majority of applications due to today’s economies of scale & increased competition. The primary reason for an increased demand in flexible graphite is due to its ability to replace a wide range of gasket materials.  What was once an expensive & complicated decision for choosing gasket materials, is now an easy & affordable choice thanks to flexible graphite. The graphite sheets are available with an anti-stick coating that avoids sticking, aides in easy gasket removal, & keeps the flanges cleaner.

Expanded PTFE Gasket Material

Expanded PTFE has been developed to seal flanges with minimal torque load. It is soft and conformable. A great solution for glass-lined pipe flanges. 

FDA approved it is a clean sealing material.

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. 

PTFE Gasket Material

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.

Non-Asbestos Gaskets

Non-Asbestos Gaskets – The removal of asbestos from the manufacturing material makes these sheets ideal for steam, oil & water sealing. We cut Non Asbestos Gaskets from all the major manufacturers materials including, Garlock, Klinger, Armstrong, Tedit, FMI, Johns Manville, Dx Seal, RM, etc.

Non-Asbestos Material

The essential difference between asbestos & non-asbestos material is that the former contains asbestos, which served as a reinforcing fiber whilst non-asbestos gaskets do not. As a result of serving as a reinforcing fiber, asbestos has a reputation for being strong & having tremendous resistance to chemicals & heat. These properties make asbestos the ideal gasket fiber, unfortunately they also make it a dangerous substance to work with.

Aflas Sheet Gasket Material

The term Aflas Gaskets is a widely known trade name which refers to the combination of materials including fluorolastomer which is made using elastomer and TFE/P combination. This material is a unique blend of rubber and plastic. Aflas Gaskets are especially good at resisting petroleum products. It also does well in steam.  If your looking for the chemical compatibility range of FKM (Viton) but compatibility with steam, Aflas is a great solution. It displays excellent heat and chemical resistance.
TEMPERATURE RANGE :- 20°F to 400°F

Rubber Sheet Gasketing

Rubber Gasket Materials – Rubber is arguably the most common gasket material used, and is available in numerous different styles. The most common are Buna-N (Nitrile), Neoprene, EPDM, SBR, and Red Rubber.

Rubber is undoubtedly the most common class of materials when it comes to sealing in the medium temperature range (-58°F to 300°F). The rubber material is especially useful because of its ability to quickly return to its original form once any deforming stress or load is removed.

Most importantly you must select the right rubber for your application. There often are several different rubbers at various price points capable of handling the same application. For assistance in selecting the right material, contact our sales staff.

Beater Addition Gasket Materials

Armstrong Gaskets has historically been the best-known beater addition gasket materials. Beater additions materials are made in a process similar to paper. Produced from a pulp which can be made of Variations in the formula blend. Depending on the rubber compound and the filler materials (cork, mineral fiber, kevlar, etc), the properties of each style will vary. We can help match the style to your application resulting in long-lasting gaskets that don’t leak.  We offer a variety of brands including Armstrong, Interface Solutions, and Fibreflex.

STYLE 0783 PLANT FIBER BUNA-N BEATER SATURATED (ARMSTRONG CN-705)

Composed of cellulose fiber, cork, & Buna-N. Typically used in applications involving oil, gasoline, & water services. This material is powered by the combination of high compressibility and high crush strength. Tensile strength minimum: 1000 PSI. Temperatures to 300°F.

Metal Gaskets

Kamm Gaskets – There are wide range of metal gaskets available which are made using rugged metal components and controlled Graphite or PTFE density. Industries make use of soft, hard and semi-soft metals as per their practical application requirements.

Spiral Wound Metallic Gaskets

ASP Style Metallic Gaskets – Metallic gaskets are commonly used in the industry and when they are produced to meet the compliance policy and specific requirements of ASP Style, they fall under this product category.

API RTJ Gaskets

API RTJ Gaskets – These are one of the types of gaskets available which are briefly known as ring type joint gaskets that will be manufactured with API well head equipment. There are rubber coated variants as well as others available based on specifications.

Frequently Asked Questions

Question: WHAT GASKET MATERIAL BRANDS ARE BEST?

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.

IS THERE A UNIVERSAL GASKET MATERIAL ?

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.

WHAT IS THE EASIEST WAY TO KNOW WHICH GASKET MATERIAL IS BEST?

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.

WHAT EQUIPMENT DO YOU CUT GASKETS WITH?

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.
