Flexible Vinyl Tubing

Vinyl is an incredibly versatile material used to make tubing for many purposes

Flexible Vinyl Tubing  - Buying Guide

Factors to consider when selecting vinyl tubing include length you need, diameter required, and the substance the tube will be transporting.

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 chart below for information about the two common types of flexible vinyl tubing:

Type Function Application Points to Consider

Clear

  • Low pressure applications with low volumes
  • Use with chemicals, gases and liquids
  • You can monitor flow and see clogs immediately
  • Washing machines
  • Dishwasher inlets
  • Drain hoses
  • Spas
  • Bathtub jets
  • 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

  • Supply and drainage lines
  • Evaporative coolers
  • Fish tanks
  • Backyard ponds
  • Water gardens
  • 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.
