When deciding which Viton® materials to use for a certain sealing application, there are a lot of considerations to weigh. Hydraulic oil, gasoline, kerosene, vegetable oils, diluted acids, hydrocarbons, and hydraulic oil can all be used with Viton®.
Nitrile, also referred to as NBR rubber and Buna-N, is the most commonly utilized and cost-effective elastomer in the seal business. Its exceptional resistance to fuels, water, alcohols, silicone greases, hydraulic fluids, and petroleum-based oils is one reason for this.
Oil seals are used to prevent grease or oil from escaping and dirt and foreign objects from entering shafts and bearings. Typically, an oil seal is composed of an outer circular metal component and an inner flexible member that performs the sealing function and is joined to the metal component using chemical adhesive agents.

Polytetrafluoroethylene, or PTFE, is used as a seal material.PTFE is rigid, hardly elastic, and exhibits rapid heat expansion. PTFE only approaches its original state when it is slightly stretched. This plastic, irreversible deformation happens even at room temperature at higher elongations.
Viton seals have outstanding resistances to oxidation, ozone, UV exposure, weather, fungus, and mildew. Their extraordinarily broad spectrum of chemical resistances makes them an ideal choice for most applications involving lubricants, fuels, and mineral acids.nbr oil seal
The housing bore diameter, the rotating shaft diameter, and the breadth (thickness) are the three dimensions that determine the oil seal size. The function of the oil seal makes the right size essential to operation.
When parts require exceptional oil resistance, nitrile rubber is one of the preferred materials. Also referred to as nitrile-butadiene rubber (NBR), this synthetic elastomer is resistant to mineral and vegetable oils as well as extended and continuous contact to petroleum-based oils.
Use of Teflon tape on fuel or oil fittings is strictly prohibited. After purchasing my Kitfox project from its original builder, I disassembled it to discover that part of the aperture was blocked by teflon tape that had moved across the threads of a fuel fitting on the header tank.
Nitrogen rubber, or NBR, is resistant to acid as well as oil, gasoline, and lubricants, which makes it an excellent material for fuel-resistant seals in automotive and aerospace applications.
