Made of FDA-compliant materials, these O-rings can withstand environments that may cause other O-rings to degrade, helping to maintain the purity of substances being processed. Use these O-rings in food and beverage production, processing, and handling equipment such as mixers, blenders, pumps, vats, and refrigerators. They can also be used in water and pharmaceutical processing applications. These O-rings have a medium hard hardness rating. All conform to AS568 standards for dimensions and tolerances.
Buna-N: Best for Oil Resistance
Choose these Buna-N O-rings for applications requiring excellent resistance to animal fats and vegetable oils. Buna-N, also known as nitrile rubber, is a strong, abrasion-resistant material that also offers good compression set resistance to minimize loss of resiliency. It is typically used for low-pressure hydraulic and pneumatic seals.

Silicone: Best for Heat Resistance
For applications where you need heat-resistant seals, choose silicone O-rings for their stability at high temperatures and resistance to aging. They can be used for sealing components of ovens, food warmers, beverage dispensers, pasteurizers, and other heated equipment.
