This yellow plastic tubing is made of Tygon formulation F-4040-A and is designed for transferring with fuel and lubricants, including gasoline and coolants. The translucent tubing permits limited ozone and ultraviolet (UV) light filtration while allowing visual flow monitoring, and the yellow color provides quick visual identification from other system tubing. The Tygon formulation F-4040-A plastic construction is designed for use with various fuels and lubricants, including gasoline, kerosene, heating oils, cutting compounds, and glycol-based coolants. It resists the swelling, hardening, and embrittlement typically caused by hydrocarbon-based fluids. The tubing has a working temperature range of -35 to 165 degrees F, a durometer (hardness) of 57A, and the working pressure ratings vary by tube size. This plastic tubing is rated as very flexible as it bends more easily than flexible or rigid tubing. The tubing is suitable for non-potable fluid service transferring coolants, heating fuels, polishing fluids and other lubricants, and for engine line and garden hose applications, among others.

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.

Saint-Gobain Corporation manufactures plastic tubing for the food and beverage, chemical processing, industrial, laboratory, medical, pharmaceutical, and semiconductor processing industries under the Tygon brand in the Saint-Gobain Performance Plastics sector. Founded in 1665, the company is headquartered in Courbevoie, France, and operates 45 plastics manufacturing sites worldwide.
