Super-Flexible in Low Temperature Applications
Parker Parflex Introduces DuraMax™ Low Temperature Hose Family
Parker Hannifin’s Parflex Division recently announced the launch of the DuraMax™ Low Temperature Hose Series, a next-generation product family engineered to perform in extreme cold weather environments.
As part of its strategic product enhancement, Parker will rebrand the legacy 55LT and 563LT hose lines under the new DuraMax™ umbrella. This rebranding will be implemented as a running change beginning June 2025.
Engineered to exceed industry expectations for flexibility, durability, and reliability, the DuraMax™ series reinforces Parker’s commitment to continuous product innovation and superior performance in demanding applications.
These new SAE 100R18 hoses will be available in two configurations:
- 53LT – Standard low temperature construction
- 538LT – Non-conductive option for applications requiring electrical insulation
The DuraMax™ series is designed for performance in extreme low temperatures, maintaining flexibility and reliability in environments as cold as -70°F (-57°C). These hoses are ideal for applications in mobile equipment, industrial machinery, and construction environments where cold weather resistance is critical.
- Superior flexibility in cold temperature applications ─ temperatures as low as -70°F
- Excellent for over-the-sheave applications
- Twin-line and multi-line constructions
- Lighter weight and more compact than equivalent rubber products
- Nylon core for improved fluid compatibility
