LP Gas Hose
Stainless Steel Reinforced – Rubber Cover
UL21
Series 7233
Series 7233 is a rubber covered, small diameter, extremely durable liquefed petroleum
gas (LPG)/propane transfer hose for applications such as fuel line hose on forklifts and
utility equipment. Te hose meets all Underwriter Laboratories (UL21) requirements. Te
construction incorporates high tensile stainless steel braided reinforcement for superior
strength, durability and kink resistance. Te perforated rubber cover is resistant to mild
chemicals, oil and ozone. Series 7233 is qualifed with Parker crimp couplings and is
compatible with Parker Series 20 reattachable fttings.
NOTE:
Refer to the Safety and Technical section of this catalog for safety, handling and use
information.
Series 7233 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 7233 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 7233 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 7233 and Compressed Natural Gas (CNG):
Series 7233 is not to be used for any
CNG application, including fuel dispensing, on-board vehicle fuel lines, or fuel transfer.
