❓ Frequently Asked Questions About Complete O-Ring Kits
What makes this a "complete" O-ring kit compared to others? 📦
Our complete O-ring kit features the full range of sizes from 5mm to 140mm OD with a consistent 1.9mm cross-section. This covers virtually every common application, from tiny electronic components to larger industrial equipment. Unlike partial kits that only include certain sizes, this comprehensive set ensures you'll have the right seal for any project.
How many pieces are included in this complete NBR O-ring set? 🔢
This comprehensive O-ring kit includes multiple pieces of each size from 5mm to 140mm OD. The exact count varies by kit configuration, but you'll receive enough seals to handle numerous repairs and projects. Check the product listing for specific piece counts and kit configurations available.
Are these suitable for automotive fuel system applications? ⛽
Absolutely. The NBR material in these O-rings is specifically formulated for excellent resistance to petroleum-based fluids. They're perfect for gasoline, diesel, motor oil, and most hydraulic fluids, making them ideal for fuel lines, filters, carburetors, and other automotive sealing applications.
What's the advantage of the 1.9mm cross-section over other thicknesses? 📏
The 1.9mm thickness represents the "Goldilocks zone" for most general-purpose applications. It provides more material than thinner 1mm or 1.5mm O-rings for better extrusion resistance in medium-pressure applications, while remaining more flexible and easier to install than thicker 2.5mm or 3mm O-rings. This balanced profile makes it the most versatile choice for the majority of sealing tasks.
How should I store my complete O-ring kit for maximum lifespan? 🗄️
Store your O-ring assortment in a cool, dry place away from direct sunlight, ozone sources (like electric motors), and extreme temperatures. The original packaging is designed for proper storage, or you can use sealed plastic bags or containers. Keep them organized by size for easy access during projects.
