O‑ring 342 — NBR 90A
Dimensions: 91.44 ± 0.71 mm (ID) × 5.33 ± 0.13 mm (CS)
Specification: AS568A, size 342
Material: NBR (Nitrile Buna-N)
Hardness: 90 Shore A
Notes:
Suitable for applications requiring good oil and fuel resistance; limited performance with strong acids, ketones, and ozone exposure.
Temperature range (typical for NBR 90A): approximately -30°C to +120°C; verify for specific compound and service conditions.
Tolerances comply with AS568A standard; confirm mating groove dimensions for proper squeeze and sealing.
For critical or safety applications, request material certifications and test data (compression set, tensile, elongation, hardness).
