1. Product Advantages
The Forever Seals O-Ring Kit stands out with three core strengths:
Durable Material: Crafted from premium nitrile rubber (NBR), these O-rings resist oil, grease, water, and mild chemicals, ensuring a service life 30% longer than standard rubber O-rings. They maintain elasticity in temperatures ranging from -40°F to 212°F (-40°C to 100°C), adapting to harsh working environments.
Cost & Time Efficiency: The kit eliminates the need for frequent single-O-ring purchases. With all essential sizes in one package, it cuts down 50% of the time spent searching for matching parts during maintenance or repairs, reducing equipment downtime.
Organized Storage: Housed in a shockproof, compartmentalized plastic case, each O-ring size is labeled clearly. The case is lightweight (only 1.2 lbs) and portable, making it easy to carry to job sites or store in workshops.
2. Working Principle
O-rings create a reliable seal by leveraging compression force. When installed between two mating surfaces (e.g., in pipes, valves, or hydraulic cylinders), the O-ring is squeezed to fill the gap. Its elastic nitrile rubber material rebounds to maintain consistent pressure, blocking the flow of fluids (liquid or gas) and preventing leaks. This simple yet effective design ensures a tight seal even under moderate pressure (up to 1,500 PSI for standard sizes).
3. Product Details
Kit Composition: Each kit includes 250+ O-rings (varies by size) plus a reusable measuring tool to verify O-ring dimensions quickly.
Case Features: The case has a snap-lock lid to prevent spills, and transparent compartments for easy visibility of each size. It also includes a size chart sticker on the inside lid for quick reference.
Quality Assurance: Every O-ring undergoes strict quality checks—including dimensional accuracy (±0.005 inches) and elasticity tests—to meet ISO 9001 standards.
