These viton gaskets are a practical purchase for anyone doing essential oil extractions with butane as they offer an incredibly high resistance to oils, fuels, lubricants and most mineral acids. These gaskets meet today's sanitary standards for the sanitary industry.

Viton was first introduced in the 1950's for the aerospace industry to fulfill the need for a high performance sealing elastomer. Since then, viton has maintained a reputation for its outstanding performance in extreme heat and extremely corrosive environments.

Viton offers an exceptionally high resistance to compression set, even at high temperatures. It is known to have an exceptionally good resistance to oxidation, sun and weather, along with an excellent resistance to fungus and mold.

Viton is capable of withstanding high temperatures while retaining its good mechanical properties, and is better at it than most other elastomers. The oil and chemical resistance are virtually unaffected by elevated temperatures, and the compounds remain relatively elastic indefinitely up to temperatures of 400° F (204° C). 

• 3,000 hours @ 450° F (232° C)
• 1,000 hours @ 500° F (260° C)
• 240 hours @ 550° F (288° C)
• 48 hours @ 600° F (316° C)

Viton is usually serviceable in applications down to between 0° F and -10° F (-18° C to -23° C). It has also been proven to be satisfactory for static seals under conditions approaching absolute zero temperatures.

DETERMINING TRI CLAMP SIZE

Tri Clamp sizes are determined by the outer diameter of the pipe or tubing, not the outer diameter of the flange or Tri Clamp itself. The flange of a Tri Clamp fitting typically has about a ½” inch greater diameter than the outside diameter of the pipe. This can become especially confusing when the Tri Clamp fitting has no pipe attached to it, as is the case with adapters, For instance, a 1.5" Tri Clamp to 1/2" hose barb adapter is not 1.5" inches in any dimension, but the Tri Clamp end will fit any other 1.5" Tri Clamp fitting. 

If you have any doubts about what size Tri Clamp fittings your project needs, simply measure the outside diameter of the flange (dimension "B" below) and consult the chart below, or feel free to contact us .
