Product Specification

-
The N70312 is an AS568-312 black Neoprene (Chloroprene) 70 Shore A O-Ring with an inside diameter of 0.6 in (15.24 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.02 in (25.91 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Neoprene (Chloroprene) is widely chosen for a balanced combination of oil and weather resistance, good resilience across a moderate temperature band. The material holds up against refrigerants and ammonia, sunlight and salt spray, and moderate petroleum oil exposure. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Applications involving strong oxidizing acids or ketones call for a different compound.

Common environments for this compound include HVAC and refrigeration, general industrial, and weather sealing and enclosures.

Order part number N70312, sold individually. Unit weight is approximately 2.0208 g. Review your operating media and conditions against this specification before installation.
