Metal-Detectable High-Temperature Silicone O-Ring Cord Stock

Create round-profile O-rings for sealing applications near ovens and other hot areas in your food plant. Made from silicone, this cord stock holds up to high heat, and won’t degrade from water, oil, and detergents. It also contains a metal additive that will set off metal detectors if it falls into your line, so contaminated food doesn’t leave your facility. The red color is easy to spot, so you can quickly find and remove any pieces from your line. This cord stock helps you comply with Hazard Analysis and Critical Control Point (HACCP) programs. It’s FDA compliant, so it’s safe for direct contact with food. It also meets ASTM D2000, which is a performance standard for rubber used in automotive applications.
