❓ Frequently Asked Questions About Ultra-Thin 1mm NBR O-Ring Seals

Why choose 1mm thickness for small repairs? 📐

1mm ultra-thin O-rings are specifically designed for applications where space is extremely limited. They fit into smaller grooves than standard 2mm O-rings, making them ideal for compact automotive components, small appliances, and precision instruments. Their slim profile allows for easier installation in tight spaces while still providing reliable sealing for low-pressure applications.

What pressure can these 1mm O-rings handle? 💧

These 1mm ultra-thin O-rings are suitable for low-pressure applications, typically handling pressures up to 300-500 PSI, depending on the specific application and groove design. They're perfect for most small automotive systems, appliance water systems, pneumatic tools, and precision equipment. For higher pressure applications, we recommend our thicker cross-section O-rings (2.4mm, 3.5mm, or 5mm).

Are these suitable for fuel and oil applications? ⛽

Yes, absolutely. NBR (Nitrile) rubber is specifically formulated for petroleum-based products. These 1mm oil-resistant O-rings work excellently with gasoline, diesel, motor oil, transmission fluid, and most hydraulic fluids. They're an excellent choice for small automotive fuel system components, oil-related applications, and machinery with petroleum-based lubricants.

Should I choose the 2-piece or 5-piece pack? 📦

The 2-piece pack is perfect for a single repair where you know the exact size needed and want a spare. The 5-piece pack is ideal for projects where you might need to test fit or want extra seals for future use. Both options are great for quick repairs without the commitment of larger quantities.

How do I measure for the correct 1mm O-ring size? 📏

For ultra-thin O-ring sizing, use calipers to measure the groove's Inner Diameter (ID) and width. The O-ring's OD should be slightly larger than the groove's ID to ensure proper sealing. Our 1mm cross-section requires a groove width of approximately 1.2-1.5mm. If replacing an existing O-ring, measure its OD and cross-section to find the exact match in our 4-63mm OD range.
