CHEMICAL RESISTANCE

John Guest Black LLDPE tubing is UV stabilized and can be exposed to direct ultraviolet

light (e.g. direct sunlight); other colors of John Guest LLDPE tubing are not UV stabilized and

cannot be exposed to direct ultraviolet light.

EXPOSURE TO ULTRAVIOLET LIGHT

John Guest LLDPE tube is suitable for pneumatic applications providing pressure is maximum

150 psi @ 70ºF (10 bar @ 20ºC). At elevated temperatures 120°F+ (50ºC+) mineral oil will

degrade LLDPE tube and, therefore, LLDPE tube used in pneumatic circuits should be

periodically checked and replaced if necessary.

For use with chemicals or potentially aggressive liquids, please refer to our Technical

Service Department.

NOTE: When using cleaning agents or other potentially aggressive liquids, please ensure

compatibility with tubing and ﬁttings. LLDPE is not recommended for mineral oils, gases and

fuels or high pressure compressed air / pneumatic systems.

TUBE INSERTS

If the tube is used in a warm water system a tube

insert is necessary.

John Guest Ltd LLDPE tubing is suitable for potable cold water applications with a MAXIMUM

chlorine content of 4 parts per million (4ppm). Heated water above 70ºF (20ºC) and/or

pressures above the maximum will signiﬁcantly reduce its service life. Direct exposure to

sunlight will also signiﬁcantly reduce its useful service. As part of good practice tubing should

be inspected regularly. If there is any evidence of damage, hardening or cracking it should be

replaced immediately.

NOTE: Hot and cold water plumbing systems must comply with local plumbing code for pipe

and ﬁttings.
