Precision Seals for Fluid Systems

These nitrile rubber O-rings measure 35 mm outside diameter, 29 mm inside diameter and 3 mm cross-section. They suit pressure washers, filters, pumps, water hoses, plumbing pipe and general garage maintenance where a reliable cylindrical seal is required.

Temperature Range and Material Limits

The 70 A durometer compound operates from -20 °C to 100 °C. Nitrile resists petroleum oils, greases and hydraulic fluids but degrades in acetone, ethers, esters, ozone and prolonged sunlight.

Pack Quantity and Installation Note

A pack of 50 rings provides spares for recurring maintenance. Verify the exact size and material compatibility before fitting, and ensure each ring seats correctly in its groove.

Questions about this item

How do I install the 35mm OD nitrile O-ring and what step is often missed?

Seat the 3mm cross-section evenly in the groove, confirm the 29mm inner diameter matches the shaft, then lubricate with compatible grease before assembly.

What maintenance or replacement will these 70A durometer rings need later?

Inspect for hardening, cracking or swelling from oil exposure; replace the 50-piece set when seals no longer hold pressure at 100°C.

What limit appears first under sustained use at 212°F?

Heat aging hardens the nitrile, reducing elasticity and causing leaks before chemical attack from petroleum fluids becomes critical.
