1.5" PTFE 100 Mesh Screen Tri Clamp Gasket

These PTFE gaskets, commonly known as Teflon gaskets, are best known for their low-friction property. High melting temperature, high corrosion resistance, high resilience and a long product life increases its value as a sealing material. One important property for these gaskets are their lack of memory that results in material creep. This allows them to seal and conform to the mating surface providing a secure seal. 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 .     Pipe Outer Diameter A Flange Outer Diameter B Pipe Inner Diameter C 1" 1.98" .87" 1.5" 1.98" 1.37" 2" 2.52" 1.87" 2.5" 3.05" 2.37" 3" 3.58" 2.87" 4" 4.68" 3.83" 6" 6.57" 5.78" 8" 8.57" 7.78" 10" 10.57" 9.69" 12" 12.57" 11.81"
