As a material, Neoprene (Chloroprene) is specified for good resilience across a moderate temperature band, a balanced combination of oil and weather resistance. The compound resists moderate petroleum oil exposure, mild acids, and refrigerants and ammonia. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving aromatic hydrocarbons or chlorinated solvents call for a different compound.
You will find this material specified across marine equipment, transit and rail, and HVAC and refrigeration.
Reference part number N70455 when ordering; the item is sold individually. Unit weight is approximately 56.8646 g and nominal inside diameter is listed as 13 inch.
