A-11275 Waterjet spare parts Spring engerized Rod Seal 60k ESL 94k HyperJet INTENSIFIER ROD SEAL descripton:

1. Nitrile rubber

Nitrile rubber has excellent resistance to fuel oil and aromatic solvents, but it is not resistant to media such as ketones, esters and hydrogen chloride. Therefore, oil-resistant sealing products and nitrile rubber are mainly used. 

2. Neoprene   

Neoprene rubber has good oil and solvent resistance. It has good resistance to gear oil and transformer oil, but it is not resistant to aromatic oils. Neoprene rubber also has excellent resistance to weathering and ozone aging. The cross-linking rupture temperature of neoprene rubber is above 200℃, and neoprene rubber is usually used to make door and window sealing strips. Chloroprene rubber also has good corrosion resistance to inorganic acids. In addition, because neoprene rubber has good flexibility and gas impermeability, it can be made into diaphragms and vacuum sealing products.

3. Natural rubber  

Compared with most synthetic rubbers, natural rubber has good comprehensive mechanical properties, cold resistance, higher resilience and abrasion resistance. Natural rubber is not resistant to mineral oil, but it is more stable in vegetable oils and alcohols. In the hydraulic brake system of the brake fluid composed of a mixture of n-butanol and refined castor oil, the rubber bowl and the apron are all made of natural rubber. Generally, the sealant is also made of natural rubber. 

4. Fluorine rubber  

Fluorine rubber has outstanding heat resistance (200～250℃) and oil resistance. It can be used to make cylinder liner seals, rubber bowls and rotating lip seals, which can significantly increase the service time.

5. Silicone rubber  

Silicone rubber has outstanding high and low temperature resistance, ozone resistance and weather aging resistance. It can maintain its unique flexibility and ozone resistance and weather resistance within the working temperature range of -70 to 260 ℃. It is suitable for the production of thermal institutions. Required gaskets, such as strong light source lampshade gaskets, valve gaskets, etc. Since silicone rubber is not resistant to oil, has low mechanical strength, and is expensive, it is not suitable to make oil-resistant sealing products.

6. EPDM rubber  

The main chain of EPDM rubber is a fully saturated linear structure without double bonds, and its side chain has diene, so that it can be vulcanized with sulfur. EPDM rubber has excellent aging resistance, ozone resistance, weather resistance, heat resistance (can be used for a long time in an environment of 120 ℃), chemical resistance (such as alcohol, acid, strong alkali, oxidant), but not Resistant to aliphatic and aromatic solvents. EPDM rubber has the lowest density in rubber and has high filling characteristics, but it lacks self-adhesiveness and mutual adhesion. In addition, EPDM rubber has outstanding steam resistance and can be used to make sealing products such as steam resistant diaphragms. EPDM rubber has been widely used in washing machines, TV accessories and door and window sealing products, or in the production of multiple composite profiles.

7. Polyurethane rubber  

Polyurethane rubber has excellent abrasiveness and good airtightness, and the temperature range is generally -20～80℃. In addition, it has medium oil resistance, oxygen resistance and ozone aging resistance, but it is not resistant to acid, alkali, water, steam, and ketones. It is suitable for manufacturing various rubber sealing products, such as oil seals, O-rings and diaphragms.

8. chloroether rubber  

Chloroether rubber has the advantages of nitrile rubber, neoprene rubber, and acrylic rubber. Its oil resistance, heat resistance, ozone resistance, flame resistance, alkali resistance, water resistance and organic solvent resistance are all very good, and it has good process performance. Its cold resistance is poor. When the operating temperature is not too low, chloroether rubber is still a good material for sealing products such as oil seals, various sealing rings, gaskets, diaphragms and dust covers.
