1. Product Advantages
The EuroSnodi Yellow O-Ring Kit from Forever Seals stands out with targeted benefits, rooted in its NBR material and Shore A 70 hardness:
Optimal Flexibility & Durability: Made of premium nitrile rubber (NBR) with Shore A 70 hardness, these O-rings strike a perfect balance—flexible enough to conform to uneven mating surfaces for tight seals, yet durable enough to resist wear, oil, grease, and water. They maintain elasticity in temperatures from -40°F to 212°F (-40°C to 100°C), outperforming softer O-rings in long-term use.
Cost & Time Savings: The all-in-one kit eliminates frequent single-O-ring purchases. With labeled compartments, it cuts 40% of the time spent searching for matching sizes during maintenance, reducing equipment downtime and operational costs.
High Visibility: The bright yellow color makes O-rings easy to spot during installation or inspection, lowering the risk of misplacement or missed parts—critical for fast-paced industrial or plumbing tasks.
2. Working Principle
Leveraging its NBR material and Shore A 70 hardness, the O-ring creates reliable seals through compression sealing technology. When installed between two mating surfaces (e.g., pipes, valves, hydraulic cylinders), the O-ring is squeezed to fill gaps. Its Shore A 70 elasticity ensures it rebounds quickly, maintaining consistent pressure to block liquid or gas leaks. Unlike harder O-rings that crack under pressure or softer ones that deform, this hardness level delivers stable performance even under moderate pressure (up to 1,200 PSI).
3. Product Details
Kit Composition: Each kit includes 240+ O-rings (22 common sizes), a durable, shockproof plastic case (1.3 lbs), and a printed size chart (attached inside the case lid) for quick reference.
Case Features: The case has snap-lock closures to prevent spills and transparent compartments for easy visibility of each size. It’s compact (9x6x2 inches) for portability to job sites or storage in workshops.
Quality Assurance: Every O-ring passes ISO 9001 and RoHS certifications. Dimensional accuracy (±0.004 inches) and hardness consistency (Shore A 68-72) are verified through 3-step quality checks to ensure reliability.

6. FAQ
Q: Is NBR (nitrile rubber) suitable for chemical exposure?
A: Yes—NBR resists mild chemicals, oil, and grease, but avoid strong solvents (e.g., acetone). For chemical-heavy applications, contact us for Viton material upgrades.
Q: How do I confirm if an O-ring from the kit fits my equipment?
A: Use the included size chart to match the old O-ring’s inner diameter (ID) and cross-section. If unsure, our customer team can help with size verification.
Q: What’s the shelf life of these O-rings?
A: When stored in the original case (away from sunlight and extreme heat), they have a 5-year shelf life.
