Flange Gaskets in USA

Flange Gaskets are used to join or fit between two sections of pipeRing Gaskets and Full Face Gaskets.each pipe section has a flared area that provides a surface for the gasket.

We cut our own custom gaskets from quality Gasket Materials to meet your specifications. Our gasket materials stock includes quality brands AS&P, Durlon, Sichem, Thermoseal, Grafoil, Leader, and Teadit. We can cut other brands including Garlock, Frenzelit, Sepco, Utex, Interface Solutions, Etc.

Gasket material is used to seal joints between 2 flat surfaces. Knowing what to place between flanges or mating pieces requires understanding what demands the joint may see. The material used for your gasket must be compatible with the temperatures, pressures, and media the gasket will see. The sealing materials that will seal the widest range of applications are Flexible Graphite and Expanded PTFE.

The gaskets we recommend are based on sound engineering. Time-proven solutions to fluid sealing problems are our specialty. As an independent family-owned business, we can supply the best gasket material to cut your gaskets from and cut them for you quickly.

The key to producing a quality gasket is to use only the best gasket materials. We pride ourselves on cutting materials from the finest grade manufacturers including; Durlon, Grafoil, Sichem, Garlock, Thermoseal, AS&P and others.

With over 30 years of dealing with every type of industry and solving gasket sealing applications from each of them, we have solutions.

Most of the sheet material we cut is made in the USA. Our objective, however, is to provide quality sealing solutions from the best possible quality source.

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

Non-Asbestos Material

Just as Asbestos came in multiple grades, and was combined with different rubber compounds, the same is true with non-asbestos materials. Each fiber serves as a reinforcement against pressure. Non-asbestos gaskets contain one of multiple asbestos replacements. Common non-asbestos fibers include, Aramid, Kevlar, Fiberglass, and mineral fiber. Each fiber and elastomer combination performs differently resulting in the need for multiple non-asbestos gasket styles.

Kevlar (an aramid fiber) is known for being approximately 2 to 9 times more durable than asbestos. These fibers then create a unique blend with different polymers to meet the needs of varieties of applications.

NON-ASBESTOS MATERIALS ARE OFTEN USED IN THE FOLLOWING APPLICATIONS:

Oil & Gas Production, Automotive, Chemical Processing, Mining, Petrochemical, Refining, Pulp and Paper, Power generation, and may more.

Today’s major manufacturers include: Garlock, Gasket Resources Inc. (Durlon), and Thermoseal (previously Klinger USA). The majority of manufacturers are now producing off shore. Garlock produces sheet in Mexico and the USA for North American consumption. Gasket Resources Inc. produces in North America, Thermoseal produces domestically in Ohio (USA) and Internationally. Sourcing of course is a dynamic situation and subject to change.

No matter who the manufacturer is, the basics are the filler and the elastomer used. There are no two compounds (or the % of filler) that are identical, having said that, the basic elastomers are: NBR (Buna-N), SBR, EPDM, or Neoprene. If you examine which material you need (as specified by the application) and choose the non-asbestos gasket material with that elastomer you will have good results. Through the use of this method, you are now able to choose a competitive brand that will assist your application.

In general, the typical “Binders” are: NBR, SBR, Neoprene, and EPDM.

To simplify things, each material listed will indicate the “binder”, despite who the manufacturer is. This provides ease when cross-referencing equivalent materials. It is important to also pay attention to Tensile Strength (for pressure resistance), Temperature Ratings, and Compression/Recovery Ratings.

For optimal performance, also consider Size, temperature, application, media, pressure, speed (if dynamic) of your specific application.

For finished gaskets consider Bolt loads, the size of bolts, the number of bolts, the bolt material and available torque.

Each manufacture we represent has it’s own strengths and weaknesses. Durlon is our preferred brand based on the quality, consistency and availability. Below you will find a listing of the sheet materials we can cut gaskets for you from. 

Durlon Gasket Materials,

Produced by Gasket Resources – We offer each of Durlon’s styles for superior sealing.
