-254 RED SILICONE 70D FDA O-RING

The S70FDA254 is an AS568-254 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 5.484 in (139.29 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 5.762 in (146.35 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Silicone is specified here for excellent electrical insulating properties and very good compression set resistance across its range. This material stands up to many oxidizing chemicals, extreme heat and cold, and weathering. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service. It is not the right choice where hydrocarbon fuels and oils or steam above its rated range are present.

This item meets FDA requirements for food contact under 21 CFR 177.2600. Maintenance and OEM teams specify it across electronics and electrical enclosures, medical devices, and sanitary process lines.

S70FDA254 ships individually. Unit weight is approximately 6.082 g. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
