Product Introduction

Crafted from **silver-plated 321 stainless steel**, this metal O-ring is engineered to deliver exceptional performance in demanding industrial applications. Its robust construction ensures reliability across extreme conditions, making it a versatile choice for both static  sealing needs.

### Key Specifications

- **Material**: Silver-plated 321 stainless steel, combining the corrosion resistance of 321 stainless steel with the enhanced conductivity and low-friction properties of a silver plating.

- **Pressure Resistance**: Capable of withstanding extreme pressures up to **11,000 psi**, ideal for high-pressure systems where seal integrity is critical.

- **Temperature Range**: Operates reliably in a wide spectrum from **-40°F to 1500°F** (-40°C to 815°C), adapting to both cryogenic and high-heat environments.

- **Hardness**: Boasts a Rockwell hardness of **HV200**, striking a balance between durability and flexibility for consistent sealing performance.

### Chemical Compatibility

This O-ring exhibits excellent resistance to a broad range of fluids and chemicals, including:

- Lubricants: Greases, mineral oil, engine oil, and synthetic lubricants

- Hydraulic fluids: Hydraulic oil and brake fluid

- Solvents: Acetone, benzene, butanol, methyl ethyl ketone (MEK), and fluorinated solvents

- Alcohols: Ethanol, isopropanol, and methanol

- Other substances: Animal oil, vegetable oil, boric acid, dilute salt solutions, and sodium bicarbonate.

### Compliance & Applications

All dimensions adhere to the **SAE AS9373 standard** for precise fit and interchangeability. It is well-suited for diverse static and dynamic sealing applications across industries such as aerospace, automotive, oil and gas, chemical processing, and power generation.

Trust in its durability, temperature tolerance, and chemical resistance to maintain leak-free performance in your most challenging systems.
