Neoprene (Chloroprene) is widely chosen for a balanced combination of oil and weather resistance, good resilience across a moderate temperature band. This material stands up to moderate petroleum oil exposure, sunlight and salt spray, and mild acids. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in strong oxidizing acids or chlorinated solvents.
You will find this material specified across transit and rail, HVAC and refrigeration, and marine equipment.
Order part number N70144, sold individually. Unit weight is approximately 1.56 g and nominal inside diameter is listed as 2 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
