4MM CS X 22MM ID RED SILICONE 70D

APG stocks the S4X22, a red Silicone 70 Shore A O-Ring with an inside diameter of 22 mm (0.866 in), a cross section of 4 mm (0.157 in), and an outside diameter of 30 mm (1.18 in). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Silicone offers physiological inertness and low toxicity, an exceptionally wide service temperature range. The compound resists dry heat, many oxidizing chemicals, and extreme heat and cold. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). Applications involving abrasive dynamic service or concentrated acids call for a different compound.

The compound meets FDA requirements for food contact. Maintenance and OEM teams specify it across sanitary process lines, electronics and electrical enclosures, and food and beverage processing.

Stocked as S4X22 and sold individually. Unit weight is approximately 1.418 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
