XLPE Corrugated Chemical Hose
Series 7274
Series 7274 is a fexible suction and discharge hose designed to handle many commonly
used acids, chemicals and solvents. Te cross-linked polyethylene (XLPE) tube will not
leach into and contaminate the product being conveyed. Te corrugated hose construction
incorporates a wire helix that provides full suction capability, fexibility, kink resistance and
a path to conduct a static electrical charge to ground. Te cover is resistant to abrasion, mild
chemicals and ozone. Series 7274 is available in 200-foot continuous lengths.
NOTE:
Refer to the Safety and Technical section of this catalog for safety, handling and
use information. Refer to the Chemical Guide section of this catalog to determine
compatibility with specifc chemicals. Contact Parker for additional chemical
compatibility information.

WARNINGS!
It is the responsibility of the user to determine if the hose is suitable for the application. Most chemical resistance guides are based on
temperatures of 70°F (21°C). Elevated temperatures can change the chemical resistance ratings. Many chemicals will become more
aggressive as temperatures increase, reducing the ability of hose compounds to withstand them. Contact Parker for chemical compatibility
data at elevated temperatures. If no data exists, users are required to perform compatibility testing at the desired temperature.
At operating temperatures of 125°F and above, only permanently attached couplings should be installed. At any operating temperature,
couplings attached with bands or clamps may reduce the working pressure of the hose assembly to less than the maximum rated working
pressure of the hose. Refer to the NAHAD Industrial Hose Assembly Guidelines.
Do not use with internally expanded couplings. Refer to chemical hoses that incorporate a MXLPE tube.
