HNBR O-rings for fluid sealing
This pack supplies fifty green HNBR O-rings designed for automotive fluid systems. The nitrile material carries a 70A durometer rating and meets ASTM D2000 and SAE J200 specifications. Technicians use them to seal connections in air-conditioning, fuel and hydraulic circuits.
10 mm inside diameter with 1.9 mm cross-section
Each ring has a nominal 10 mm inside diameter and a 1.9 mm width, giving a 13.8 mm outside diameter. The metric sizing matches standard port dimensions so the seal seats correctly without stretching or extrusion. Verify the groove dimensions before installation.
Temperature range from -15 to 100 degrees F
The compound remains functional across a -15 to 100 degrees F range, covering typical under-hood and cabin conditions. The green colour helps identify the material during inspection. The pack contains fifty pieces for multiple service jobs.

Questions about this item
What does the 70A durometer mean for sealing performance?
The 70A durometer indicates a medium-hard HNBR compound that resists extrusion under pressure while maintaining enough elasticity to seal effectively against the 1.9 mm groove width.
How does the ASTM D2000 and SAE J200 listing affect fluid compatibility?
Meeting both standards confirms the green HNBR material is tested for resistance to automotive oils, fuels and refrigerants within the specified temperature range.
Will the 13.8 mm outside diameter fit a standard 10 mm metric groove?
Yes, the 10 mm inside diameter and 13.8 mm outside diameter match a standard metric groove designed for a 1.9 mm cross-section O-ring.
