Flexible Vinyl Tubing

Characteristics

  • Withstands a variety of conditions 
  • Does not rust or corrode 
  • Electrically nonconductive 
  • Helps to prevent fires by providing natural resistance to combustion 
  • Odorless, tasteless and nontoxic

Types

Refer to the lists below for information about the two common types of flexible vinyl tubing:

Clear Flexible Vinyl Tubing

Function

  • Low pressure applications with low volumes 
  • Use with chemicals, gases and liquids 
  • You can monitor flow and see clogs immediately


Application

  • Washing machines 
  • Dishwasher inlets 
  • Drain hoses 
  • Spas 
  • Bathtub jets


Points to Consider

  • Made from non-toxic PVC compounds 
  • Available in diameters from 1/8" to 2" 
  • Polyester braiding withstands higher pressures with resistance to corrosion and abrasion; available in 1/4" to 2" diameters

Black Flexible Vinyl Tubing

Function

  • Supply and drainage lines


Application

  • Evaporative coolers 
  • Fish tanks 
  • Backyard ponds 
  • Water gardens


Points to Consider

  • Durable and resistant to clogs, ultraviolet light and ozone
  • Inhibits algae growth
  • Generally sold in 3/8" diameter rolls
  • Blends in under water

Performance Considerations

Flexible vinyl tubing is easy to connect using a variety of barbs, clamps and fittings.


  • Often comes in rolls of 25’ to 100’ 
  • Pay attention to pressure rating, maximum vacuum and minimum bend radius 
  • Pressure rating is usually a measure of how much pressure a tube can withstand at 75˚ F. 
  • Temperature range is particularly important for tubes supplying hot water 
  • Wall thickness can affect the inside diameter of a tube

Features

  • Color. Available in a wide variety of colors to blend in with the background. 
  • Antistatic. Prevents buildup of static electricity that might interfere with substances passing through. 
  • Flexibility. May contain pleats or corrugations that allow it to expand or contract. 
  • Explosion Protection. Certified by the Underwriter’s Laboratories (UL) to withstand internal explosions when transporting volatile chemicals. 
  • Spark Resistance. Designed to withstand electrical discharges or sparks. 
  • Sterilization. Sterilized to safely transport drinking water or other substances that must not be contaminated.
