1mm cross section O-rings offer several advantages: they require less installation force, fit in tight spaces where larger O-rings won't work, provide sufficient sealing for low to moderate pressure applications, and are more flexible for easier installation. Their slim profile makes them ideal for small equipment, precision instruments, and applications with limited space constraints.

Our 1mm NBR O-rings are suitable for low to moderate pressure applications, typically handling pressures up to 500 psi (34 bar) depending on the groove design and operating conditions. While thinner than standard O-rings, they provide effective sealing for most household, automotive, and small equipment applications. For high-pressure systems, consider our thicker cross section options.

To select the correct size, measure the groove where the O-ring will sit. You need the inner diameter (ID) or outer diameter (OD) and the groove width. Our 1mm cross section requires a groove width of approximately 1.2-1.5mm. If replacing an existing O-ring, match its dimensions exactly. When in doubt, order our assorted kit to have multiple sizes available for testing.

While NBR is generally safe for water applications, our standard NBR O-rings are not specifically certified for potable water. For drinking water systems, we recommend our food-grade silicone or EPDM O-rings. However, these NBR O-rings work excellently for non-potable water applications in household plumbing, appliances, and outdoor equipment.
