LDPE Tubing
LDPE Tubing - Low Density Polyethylene is economical plastic material with good chemical resistance. LDPE provides high impact strength at low temperatures. It also exhibits excellent electrical properties. relieved

Low Density Polyethylene tubing joins the Linear Low Density version, giving customers a broader selection from which to choose. Low Density Polyethylene (LDPE) tubing is used for air and pneumatic lines, fluid feeds, chemical transfer, wire jacketing, food and beverage processing, potable water systems, drains, pool and spa supply lines, and more.
We previously offered only the low density style of polyethylene, then switched to linear low density a few years ago due to its enhanced resistance to stress cracking. Although both types provide for repeated flexing with little or no signs or wear, only LDPE tubing is listed by the National Sanitation Foundation (NSF 51), an important consideration in many cases.
LDPE exhibits a high degree of inertness and forms a good barrier to gases, vapors, and moisture. It provides good dielectric properties and will not impart any taste or odor to fluids running through it. LDPE is manufactured from non-toxic, 100% virgin grade resins with ingredients that conform to FDA standards.
Durable LDPE is a lightweight tubing and is one of the lower cost plastic materials. Factory stock includes tubing in 1/4", 5/16", 3/8", and 1/2" O.D. sizes in translucent natural color and in 1/4", 3/8", and 1/2" O.D.'s in opaque black. LDPE is considered a flexible yet semi-rigid product and therefore mates well with push-to-connect fittings available in acetal or brass. Custom colors, sizes, and shapes are offered as well.

Advantages of LDPE Tubing: - cheap, good chemical resistance, high impact strength at low temperatures, excellent electrical properties
Disadvantages: - low strength, low stiffness, low maximum operating temperature, flammable, poor UV resistance, high gas permeability (particularly CO2), susceptible to environmental stress cracking
