Nitrile rubber nitrile rubber seal - suitable for oil-based hydraulic oil, ethylene glycol hydraulic oil, diester lubricating oil, gasoline, water, silicone grease, silicone and other media. It is currently a widely used and low-cost rubber seal. Not affected by polar solvents such as ketones, ozone, nitro hydrocarbons, MEK, and chloroform. The general temperature range for use is -40 to 120 ℃.

HNBR hydrogenated nitrile rubber seals - have excellent corrosion resistance, tear resistance, and compression deformation resistance, as well as better resistance to ozone, sunlight, and weather. Features such as better wear resistance than nitrile rubber. Suitable for washing machines, car engine systems, and refrigeration systems using the new environmentally friendly refrigerant R134a. Not recommended for use with alcohols, esters, or aromatic liquids. The general temperature range for use is -40 to 150 ℃.

SIL silicone rubber sealing strip - has excellent heat resistance, cold resistance, ozone resistance, and atmospheric aging resistance. Has good insulation performance. But the tensile strength is inferior to ordinary rubber and does not have oil resistance. Suitable for household appliances such as electric water heaters, irons, microwaves, etc. It is also suitable for contact with various human products such as water bottles, water dispensers, etc. It is not recommended to use solvents, oils, concentrated acids, and sodium hydroxide that are commonly used in centralized settings. The general temperature range for use is -55 to 250 ℃.

VITON fluororubber seals - superior to silicone rubber in high temperature resistance, with excellent weather resistance, ozone resistance, and chemical resistance, but poor cold resistance. Resistant to most oils and solvents, especially carboxylic acids, aliphatic hydrocarbons, aromatic hydrocarbons, and animal and vegetable oils. Sealing is suitable for the requirements of diesel engines, fuel systems, and chemical plants. Not recommended for use with ketones, low molecular weight esters, and mixtures containing nitric acid. The general temperature range for use is -20 to 250 ℃.

FLS fluorosilicone rubber seals - including the performance advantages of fluororubber and silicone rubber, good oil resistance, solvent resistance, fuel oil resistance, and high temperature resistance. Resistant to corrosion by oxygen-containing compounds, chlorine containing solvents, and aromatic solvents. Generally used in aviation, aerospace, and military applications. It is not recommended to expose to ketones and brake oils. The general temperature range for use is -50 to 200 ℃.
