Chemical Industrial Hoses | Parker | POLY-CHEM® XLPE Corrugated Chemical Hose | 7274 Series
 |
Series 7274 is a flexible suction and discharge hose designed to handle many commonly used acids, chemicals and solvents. The cross-linked polyethylene (XLPE) tube will not leach into and contaminate the product being conveyed. The corrugated hose construction incorporates a wire helix that provides full suction capability, flexibility, kink resistance and a path to conduct a static electrical charge to ground. The cover is resistant to abrasion, mild chemicals and ozone. Series 7274 is available in 200-foot continuous lengths.

WARNING!
- 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.
