Chemical-Resistant Soft Fluoroelastomer O-Ring Cord Stock
This cord stock is softer and creates a better seal than standard fluoroelastomer cord stock. It resists benzene, boric acid, ethylene glycol, and isopropyl alcohol. Use it to make round-profile O-rings, which are suitable for a wide range of static and dynamic sealing applications.

Abrasion-Resistant Rubber and Plastic Sealing Washers
Made of durable material, these washers resist wear from rubbing and scraping surfaces. They create a light duty seal around fasteners to prevent fluids from leaking and damp vibration.
Buna-N rubber washers are FDA compliant for direct contact with food. They have good oil resistance, and are commonly used in applications with plant and animal fat and oil. However, Buna-N washers have a significantly lower maximum temperature rating than Aramid/Buna-N washers and ePTFE washers.
