❓ Frequently Asked Questions About Our O-Ring Kit

Is this NBR O-ring kit suitable for gasoline applications? ⛽

Absolutely. Nitrile Rubber (NBR) is specifically formulated for excellent resistance to petroleum-based fluids. These oil-resistant O-rings are perfect for gasoline, diesel, motor oil, and most hydraulic fluids, making them ideal for automotive and small engine repairs.

How many O-rings are included in this kit? 📦

This is a comprehensive O-ring assortment covering the most useful sizes from 82mm to 370mm OD with a 3.5mm cross-section. The kit provides multiple pieces of each size to handle various repair scenarios. Check the product listing for the exact count of pieces included in this specific set.

Can I use these rubber seals for hot water applications? ♨️

Yes. With a maximum temperature rating of +248°F (+120°C), these NBR seals are well-suited for domestic hot water systems, dishwasher connections, and other applications involving heated water within their temperature range.

What makes NBR material better than other rubbers for general use? 🔍

NBR (Nitrile) offers the best balance of properties for the most common sealing applications. It provides superior resistance to oils, fuels, and greases compared to materials like EPDM or Natural Rubber, while maintaining good flexibility and compression set. For non-specialized applications involving petroleum products, NBR O-rings are typically the most cost-effective and reliable choice.

How should I store my O-ring kit to maximize its lifespan? 🗄️

For optimal longevity, store your O-ring assortment in a cool, dry place away from direct sunlight, ozone sources (like electric motors), and extreme temperatures. Keep them in their original packaging or in sealed bags to protect them from dust and contaminants until ready for use.
