O-Rings
Our O-rings are manufactured to the AS568A standard, covering sizes 001 through 475 across a full range of materials to match your application's chemical, temperature, and pressure requirements. Buna/NBR offers excellent resistance to oils, fuels, and general-purpose fluids, making it the most widely used elastomer for industrial sealing. Viton/FKM provides superior resistance to high temperatures, aggressive chemicals, and hydrocarbon-based media, available in both 75A and 90A durometer hardness. Silicone/VMQ excels in extreme temperature ranges and food-contact applications where flexibility and low compression set are critical. All materials are available in standard black, with select grades offered in red and brown to aid material identification in the field. Whether you need a high-volume bulk pack for production line maintenance or individual sizes for precision equipment repair, our catalog covers the full AS568A series to keep your operations sealed and running.
