These Viton screen gaskets are a practical purchase for anyone doing closed loop BHO extractions as these gaskets are food grade and recognized as safe and sanitary.

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 up to temperatures of 400° F (204° C) and down to -40 F (-40 C).

The mesh screen is made from 316 Stainless Steel. The stainless steel mesh screen supports a temperature up to 400° F. The screen is woven, it can be rolled, bent and put back in place with your bare hands.Screen gaskets are great for using with an oil extractor, as it keeps the plant matter from entering your final product.

Remember, when sizing the mesh screen for your filtration that the higher the number mesh the more strands per inch, i.e. 150 Mesh = 150 strands across 1 inch.

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  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  .
