LP Gas Hose
UL21, CGA Type I
Series 7232
Series 7232 is a large diameter, fexible liquefed petroleum gas (LPG)/propane transfer hose
for large volume bulk loading/unloading and vibration-resistant onboard vehicle connections.
Te hose meets all Underwriters Laboratories (UL21) and Canadian Gas Association (CGA
Type I) requirements. Te construction incorporates multiple braids of textile reinforcement
for kink resistance and superior coupling retention. Te perforated cover is resistant to mild
chemicals, oil and ozone. Series 7232 is available in long lengths and factory-tested assemblies
in popular confgurations.
NOTE:
Refer to the Safety and Technical section of this catalog for safety, handling and use
information.
Series 7232 and DOT:
LPG hose assemblies installed on on-road vehicles must meet
Department of Transportation (DOT) requirements. Factory assemblies (all sizes) are pressure
tested, one of the fttings is etched with a unique DOT certifcation number, and a document
incorporating the identical certifcation number accompanies each assembly. Metal DOT
identifcation bands are also available/attached for an additional charge at customer request.
Contact Parker.
Series 7232 and Natural Gas:
Te molecules of natural gas are small, enhancing their ability to
permeate through standard rubber hose constructions. Te permeation process is more rapid
as the working pressure increases, and natural gas accumulates with potentially dangerous
consequences. Series 7232 may be used for natural gas service, but ONLY under ALL of the
following conditions:
• Te application must be in a well-ventilated environment: Outdoors, or indoors with
signifcant continuous air movement.
• Series 7232 is not to replace fxed/rigid pipe where that material is more appropriate due
to reduced permeation and overall strength and durability. Use rigid pipe, non-permeable
tubing or hose with barrier constructions to convey natural gas whenever possible.
Series 7232 and Compressed Natural Gas (CNG):
Series 7232 is not to be used for any CNG
application, including fuel dispensing, on-board vehicle fuel lines, or fuel transfer.

3

Series 7232 is not for use with anhydrous ammonia.
