1.5mm O-rings offer the perfect balance for precision applications. They're slim enough to fit in tight spaces where larger O-rings won't work, yet provide sufficient material for reliable sealing. Their flexibility makes installation easier, especially in hard-to-reach areas. This cross section is ideal for small automotive components, household appliances, and precision equipment where space is limited but performance is critical.

Our 1.5mm NBR O-rings are suitable for low to medium pressure applications, typically handling pressures up to 750 psi (52 bar) with proper groove design. This makes them perfect for most small equipment, automotive systems, and household applications. While thinner than standard O-rings, they provide excellent sealing performance for their intended applications. For higher pressure requirements, consider our thicker cross section options.

For precision applications, accurate measurement is crucial. Measure the groove ID and width, or the mating surfaces. Our 1.5mm cross section requires a groove width of approximately 1.8-2.2mm. Use precision calipers for accurate measurements. When replacing existing O-rings, match the dimensions exactly. For critical applications, consider ordering multiple close sizes to ensure perfect fit.

While NBR is generally safe for water contact, our standard NBR O-rings are not specifically certified for drinking water applications. For potable 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 appliances, automotive cooling systems, and general plumbing.
