Product Description
Compared with similar products in the market, the rubber o ring kit of FOREVER SEALS has the following main advantages.
1. Product Advantages
The EuroSnodi Green O-Ring Kit from Forever Seals excels with targeted strengths, centered on its Shore A 90 hardness:
Superior Durability: Crafted from premium nitrile rubber with Shore A 90 hardness, these O-rings offer exceptional resistance to wear, deformation, and pressure. They maintain shape even under frequent use, outlasting standard low-hardness O-rings by 40%.
All-Weather Performance: The Shore A 90 nitrile rubber withstands extreme temperatures (-40°F to 220°F/-40°C to 104°C) and resists oil, grease, and water. This makes the kit reliable for both indoor industrial setups and outdoor plumbing tasks.
Time-Saving Organization: Packed in a labeled, compartmentalized case, each size is easy to locate. No more rummaging for matching O-rings—cut maintenance time by 35% and keep workflows smooth.
2. Working Principle
Leveraging its Shore A 90 hardness, the O-ring creates a tight, long-lasting seal through compression and resilience. When installed between mating surfaces (e.g., valves, pipes), the rigid-yet-elastic rubber is squeezed to fill gaps. Unlike softer O-rings that flatten over time, its Shore A 90 hardness ensures it rebounds quickly, maintaining consistent pressure to block fluid/gas leaks—even under 2,000 PSI of pressure.
3. Product Details
Kit Inclusions: 220+ O-rings (20 common sizes), a durable plastic case (1.1 lbs, shockproof), and a mini Shore A hardness tester (for on-site verification).
Green Color Advantage: The vibrant green hue makes O-rings easy to spot during installation/inspection, reducing the risk of missing or misplaced parts.
Quality Assurance: Every O-ring passes ISO 9001 and RoHS tests, with dimensional accuracy (±0.003 inches) and hardness consistency (Shore A 88-92) guaranteed.

5. Application Range
Designed for professional and heavy-duty use:
Industrial: Hydraulic cylinders, pneumatic tools, manufacturing machinery (presses, conveyors), and oil/gas pipelines.
Plumbing & Mechanical: Pipe joints (PVC, copper), water pumps, heating systems, and mechanical repair tasks (engine gaskets, gearboxes).
Automotive: Fuel lines, cooling systems, and brake components (compatible with gasoline, diesel, and brake fluids).
6. FAQ
Q: Why Shore A 90 hardness? Is it too rigid?
A: Shore A 90 balances rigidity and elasticity—hard enough to resist deformation, yet flexible enough to seal gaps. It’s ideal for high-pressure applications where softer O-rings fail.
Q: Can these O-rings be used with food-grade equipment?
A: Yes—our nitrile rubber meets FDA standards for food contact, making it safe for use in food processing machinery seals.
Q: How to store the kit to preserve O-ring quality?
A: Keep the case closed, away from direct sunlight, oil spills, and temperatures above 220°F. Shelf life is 6 years under proper storage.
