HNBR O-Rings for Higher-Performance Sealing
Product Overview
Shiny Unite manufactures HNBR (hydrogenated nitrile) O-rings for higher-performance sealing applications. HNBR is widely used in air-conditioning and automotive air-conditioning systems, with excellent resistance to cold media such as HCFC-134a, FC-12, R404, R407C, R410A and ammonia.
Material & Construction
Our HNBR O-rings are available in a hardness range of 60 to 90 Shore A, with a service temperature range of -40°C to 175°C.
Applications
- Air-conditioner and automotive air-conditioner systems
- Related accessories such as compressors and pipes
- Automotive and low-temperature media sealing
- Oil and water media sealing
Key Benefits
- Excellent cold-media resistance (refrigerants, ammonia)
- Higher mechanical performance than standard NBR
- Good oil and water resistance
- Suitable for demanding automotive applications
Customization & Manufacturing
We produce HNBR O-rings in custom sizes and hardness to match your drawing or specification. Send your dimensions or drawing for a quotation.
Technical Considerations
HNBR offers better heat and mechanical performance than standard NBR while retaining good oil resistance, which makes it suitable for higher-performance sealing applications such as automotive and refrigeration systems.
