-105 RED SILICONE 70D O-RING

The S70105 is an AS568-105 red Silicone 70 Shore A O-Ring measuring an inside diameter of 0.143 in (3.63 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.349 in (8.86 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

It resists dry heat, extreme heat and cold, and weathering. Silicone is widely chosen for physiological inertness and low toxicity, excellent electrical insulating properties. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). It is not the right choice where steam above its rated range or concentrated acids are present.

Maintenance and OEM teams specify it across medical devices, ovens and heated equipment, and pharmaceutical manufacturing.
