Profile: TheRubberStore.com specializes in the design and manufacturing of standard and custom molded rubber products. O-rings are available in a variety of materials and offered in both standard and metric sizes. Our engineered o ring compounds are designed to perform in a wide range of applications with varying chemical exposures, pressures and temperatures. Silicone o-rings provide resistance to ozone, oxygen, and moisture. Low physical strength and abrasion resistance combined with high friction properties limit silicone to static seal applications. The silicone o-ring is commonly referred to as a VMQ o-ring, or PVMQ o-rings. We offer a selection of both the standard AS568 o-ring and the metric o-ring. Our rubber bellows are versatile seals used in a wide range of applications to seal dust and other environmental elements in applications with a stroke or designed range of motion. We offer both straight and tapered bellow designs in various sizes and connector types.
