Products Description
Buna-N 90 boss O-ring seal kit is a seal kit specially designed for hydraulic applications, mainly made of Buna-N with a Shore hardness of 90. This material is widely used in various industrial and mechanical equipment due to its excellent oil resistance and wear resistance.
Characteristics
- Material and hardness: The seal kit uses Buna-N material with a hardness of 90 degrees. This material has good oil and chemical resistance and is suitable for a variety of industrial applications.
- Wide range of applications: These O-ring seals are mainly used in straight-thread pipe fittings (Boss Type) in hydraulic equipment for sealing and connecting pipe systems.
- Various sizes and quantities: Different products contain different numbers of O-rings, for example, some sets contain 155 pieces, while others contain 212 pieces or more to meet various needs.
- High-pressure resistance: Buna-N material is particularly suitable for high-pressure applications, so it performs well in environments that need to withstand high pressure.
- Durability and reliability: Due to the high strength and durability of Buna-N material, these O-rings can provide long-term and reliable sealing effects and reduce the risk of leakage.
- Compatibility and maintenance: These seals are generally compatible with metal or plastic accessories, and care needs to be taken during installation to avoid damaging the seals.
Buna-N O-Rings 90 Duro: exceptionally suited for high-pressure applications.
Buna-N is a copolymer of Butadiene and Acrylonitrile. It is the most commonly used elastomer for sealing products. It has a temperature range of -40F to +250F and is exceptionally resistant to petroleum-based oils and hydrocarbon fuels. Nitrile materials also exhibit excellent tensile strength and abrasion resistance properties. The material performs well with most dilute acids, silicone oils, and lubricants and in water applications.
