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.
