O-ring 336 NBR 70A
Size: 72.39 × 5.33 mm (AS568A equivalent)
Material: Nitrile Buna-N (NBR), hardness 70 Shore A
Color: Black
Key characteristics:
AS568A cross-reference for groove/standard sizing
Excellent resistance to petroleum-based oils, fuels, and hydraulic fluids
Good abrasion resistance and mechanical properties
Temperature range (typical): –30°C to +100°C (service limits depend on fluid and application)
Suitable for static and moderate-dynamic sealing applications
Not recommended for strong acids, ketones, or aromatic hydrocarbons without compatibility check
Typical applications:
Hydraulic and pneumatic seals
Automotive fuel and oil systems
Industrial machinery and equipment
General-purpose sealing where oil and fuel resistance is required
Quality & inspection:
Manufactured to AS568A dimensional tolerances
Visual inspection for surface defects; optional hardness and dimensional testing available on request
Supplied packaged to prevent contamination and deformation
Ordering information:
Specify part number 336, material NBR 70A, size 72.39 × 5.33 mm (AS568A)
Indicate required quantity, packaging preference, and any special testing or certification needs
For bulk orders or custom specifications, contact Univergo’s sales team with application details to confirm compatibility and lead times.
