Vulcanized Buna-N 70 Duro Custom O-Rings

Our Vulcanized Buna-N 70 Custom O-Rings offer precise sealing solutions for large-scale applications, ensuring robust performance with superior accuracy. Expertly manufactured to stringent Class 2 tolerances of ±0.80% to ±1.00% for sizes up to 48 inches, each O-Ring undergoes rigorous inspection including visual checks, PI Tape, and advanced Olypsys® Large Format Optical Measurement. For O-Rings above 48 inches, Class 3 tolerances of ±1.20% to ±1.50% apply, verified through visual inspection and PI Tape measurement, guaranteeing reliability in critical sealing tasks.

Olypsys® Measurement Verification Available on O-Rings < 48” (1219mm) OD
