Sterling Seal CFF7530.300.062.150 7530 Full Face PTFE Gasket - 3.5" ID, 3" Pipe Size, 1/16" Thick, Class 150 Pressure Rating, Virgin Teflon (Pack of 10) - Ideal for Plumbing, HVAC, and Industrial Pipe Flange Connections

Sterling Seal & Supply 7530 (polytetrafluoroethylene) is a high molecular weight polymer and one of the most versatile plastics known to Man Virgin PTFE sheet can handle virtually all chemicals in the 0-14 pH range with the exception of molten alkali metals and elemental fluorine It is suitable for service at temperatures from the cryogenic range up to 500 Degrees F Sterling Seal & Supply 7530 is particularly recommended for applications in the food and beverage industry where high purity materials are required It is also used where contamination or discoloration of flow media cannot be tolerated The coefficient of friction of plastics is usually measured against polished steel Ptfe's resistance to van der Waals forces means that it is the only known surface to which a gecko cannot stick In fact, PTFE can be used to prevent insects climbing up surfaces painted with the material and is so slippery, that insects cannot get a grip and tend to fall off For example, PTFE is used to prevent ants climbing out of formicaries Because of its superior chemical and thermal properties, PTFE is often used as a gasket material PTFE sheets are used in the production of butane hash oil due to its non-stick properties and resistance to non-polar solvents Its high corrosion resistance makes PTFE useful in laboratory environments, where it is used for lining containers, as a coating for magnetic stirrers, and as tubing for highly corrosive chemicals such as hydrofluoric acid, which will dissolve glass containers It is used in containers for storing fluoroantimonic acid, a superacid In industrial applications, owing to its low friction, PTFE is used for applications where sliding action of parts is needed: plain bearings, gears, slide plates, etc In these applications, it performs significantly better than nylon and Acetal; it is comparable to ultra-high-molecular-weight polyethylene Its extremely high bulk resistivity makes it an ideal material for fabricating long-life electrets

You will get maximum performance from our gasket materials when you use our gasket installation procedure. [1] clean and inspect the flanges, surface or parts that require gasket

2] clean or replace your bolts, nuts & washers. Lubricate the bolt's, thread, nuts, washers and the underside of the head with graphite based compound

3] flat washers are recommended to assure even distribution of the bolting force. Ensure lubricant doesn’t contaminate gasket. Carefully insert the gasket between the mating surfaces

4] the use of a torque wrench is highly recommended. This assures a longer life and leak free performance. Whether an automotive head gasket or a flange gasket, it should be torqued

5] make four even Increment passes in a 12-6-3-9 o'clock pattern sequence. The appropriate stress on the gasket material you use is Key to its success which varies depending material chosen
