Key Features

Oil Resistance

Review NBR compound compatibility against the exact oil, fuel, cleaning fluid and temperature. Automotive or electrical use does not by itself establish a thermal rating.

Specified Compound Hardness

Specify one nominal Shore A hardness and tolerance with the gland drawing. Compound properties, squeeze and clearance must suit the joint; the molding equipment does not define service temperature or hardness.

Variety of Colors

Available in standard black or custom colors to meet specific application requirements.

Application Notice

Store away from direct sunlight, moisture, ozone sources and heat, using the selected compound storage requirements. Storage conditions are separate from operating-temperature limits.
Store at least 1m away from heating equipment and separate from acid or alkali substances
Do not compress during storage to prevent permanent deformation
Maintain proper documentation of manufacturing and factory dates

Automotive and Electrical O-Ring Selection: Heat Cycles and Joint Exposure

Provide the seal temperature during continuous operation, short peaks and cold starts, together with exposure duration. A surrounding air temperature may differ from the temperature at the gland. Select the compound using its applicable property and compression-set data.

For an automotive joint, identify the actual oil, fuel, coolant or cleaning fluid and whether sealing is static or moving. For an electrical enclosure joint, include rain, condensation, ozone and cleaning exposure. NBR, EPDM, silicone and FKM are distinct material choices; review each against the actual duty rather than treating them as interchangeable.

Specify the AS568 dash number or nominal inner diameter and cross-section, tolerances and gland geometry. Provide the required assembly validation, such as leakage through the stated temperature cycles. An O-ring listing alone does not establish an enclosure IP rating or electrical insulation qualification.
