KWD 4
– 1 +

Special Features

  • Made of neoprene (polychloroprene) for use with a variety of fluids and gases from ammonia to Freon
  • Temperature Range: -40°C (-40°F) to 100°C (212°F); Shelf-life: 15 Years
  • Neoprene is a multi-purposed elastomer which yields a balanced combination of properties. Neoprene o-rings demonstrate remarkable resistance to chemicals such as ammonia and a variety of coolants.
  • Durometer (hardness) of 70A for resistance to penetration
  • O-ring Size meets standards defined by AS568A (b) ID (Nominal): 3-1/4 ID (Nominal): 1/8 CS (Nominal): 3-1/2 OD

Description

Neoprene (polychloroprene) can have a high tensile strength, and has abrasion, tear, and compression set resistance. It is generally fire resistant and compatible for use with ozone, sunlight, ammonia, Freon, and some hydrocarbons. It also had good adhesion to metal and is often used in metal to rubber bonding applications. Neoprene is vulnerable to ketones, acids, brake fluids and phosphate esters. This black neoprene O-ring has a durometer of 70A, a round cross-section, and can be used across a wide temperature range (-40 degrees F/-40 degrees C to 212 degrees F/100 degrees C). Designed for use in a wide variety of sealing applications, this neoprene O-ring meets standards defined by Aerospace Standard AS568A, which is the Aerospace Size Standard for O-rings.
