This flexible, lightweight black metric tubing is suitable for fluid transfer applications. It is made of nylon 12 which is strong, flexible, and lightweight, has excellent abrasion resistance, and resists crushing and cracking. It has a Shore D Hardness rating of 63 for resistance to tear or puncture, and it has excellent resistance to flexural fatigue, tube vibration and movement. It has a high bend radius for resistance to kinking and low moisture absorption for resistance to swelling due to water. This black, metric-sized tubing has an operating temperature range of -90 to +212 degrees F. Push-to-connect fittings are recommended for most applications.Plastic tubing is used to transfer liquids, air, or solids, and it is characterized by a round, rectangular, or square shape and a hollow center. Plastic tubing is crimp-resistant and varies in bend radius (flexibility), chemical resistance, wall thickness, durometer hardness, and temperature and pressure handling abilities. The clarity of plastic tubing may be transparent (clear), translucent (semi-clear), or opaque (solid), and the tubing's coloring may indicate suitable applications. Barbed fittings are used to connect tubing or redirect flow in a fluid handling system. Plastic tubing is used in a wide variety of industries, such as agriculture, automotive, laboratory, and medicine. Applications for plastic tubing include blood and fluid handling, peristaltic pumps, electrical and thermal insulation, analytical systems, and food and beverage handling, among others.
