-225 RED SILICONE 70D O-RING

APG stocks the S70MD225, an AS568-225 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 1.859 in (47.22 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.137 in (54.28 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against many oxidizing chemicals, weathering, and extreme heat and cold. That behavior comes from the compound itself: Silicone offers excellent electrical insulating properties and an exceptionally wide service temperature range. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). Applications involving concentrated acids or steam above its rated range call for a different compound.

The compound is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across pharmaceutical manufacturing, medical devices, and food and beverage processing.

Order part number S70MD225, sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
