❓ Frequently Asked Questions About 2.4mm NBR O-Ring Seals
Why are 2.4mm O-rings considered the "standard" for many applications? ⚖️
2.4mm O-rings have become the go-to choice for many applications because they offer an excellent balance of properties. They provide sufficient material thickness for reliable sealing in medium-pressure systems (up to ~1500 PSI), while remaining flexible enough for easy installation. This makes them suitable for the vast majority of automotive repairs, industrial maintenance, plumbing, and DIY projects where a versatile, all-purpose seal is needed.
What's the difference between 2.4mm and 1.5mm or 3.5mm O-rings? 📏
1.5mm O-rings are thinner and better for precision applications with tight spaces. 3.5mm O-rings are thicker and offer more material for better wear resistance in dynamic applications. 2.4mm O-rings sit in the middle - offering a versatile balance that works well for most general applications. For the majority of automotive, industrial, and plumbing repairs, 2.4mm provides the ideal combination of performance and ease of use.
Are these suitable for automotive fuel systems? ⛽
Yes, absolutely. NBR (Nitrile) rubber is specifically formulated for petroleum-based products. These 2.4mm fuel-resistant O-rings work excellently with gasoline, diesel, motor oil, transmission fluid, and most hydraulic fluids. They're an excellent choice for automotive fuel systems, industrial machinery, and any application involving petroleum products within their pressure and temperature ratings.
Can these handle hot water in plumbing applications? ♨️
Yes. With a maximum temperature rating of 248°F (120°C), these 2.4mm NBR O-rings are perfectly suitable for domestic hot water systems, including faucets, shower valves, dishwashers, and water heaters. They maintain their sealing integrity throughout the temperature range, making them reliable for most household and commercial plumbing applications.
