10' Of F-4040-A Tygon PVC Fuel And Lubricant Tubing, 1/8" ID x 3/16" OD, 1/32" Wall. 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.
