-228 RED SILICONE 70D O-RING

Ordered as S70MD228, this is an AS568-228 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 2.234 in (56.74 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.512 in (63.8 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The compound resists many oxidizing chemicals, dry heat, and ozone and UV exposure. That behavior comes from the compound itself: Silicone is known for flexibility that holds at very low temperatures and very good compression set resistance across its range. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). It is not the right choice where hydrocarbon fuels and oils or steam above its rated range are present.

This item is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across sanitary process lines, pharmaceutical manufacturing, and food and beverage processing.

This item is sold individually under part number S70MD228. Nominal inside diameter is listed as 2 1/4 inch. Review your operating media and conditions against this specification before installation.
