Parker Hannifin’s Hose Products Division has announced the Phase 1 launch of the new 7391 EPDM-P Suction & Discharge Hose, expanding Parker’s thermal management and coolant hose portfolio for demanding data center and facility cooling applications.
The new 7391 Series is designed for DI water and glycol-based coolant solutions and targets applications where high flow capacity is more important than extreme flexibility. According to Parker, the initial release focuses on larger-diameter hoses developed for facilities, large coolant distribution units (CDUs), and data center infrastructure.
What Is the Parker 7391 EPDM-P Hose?
The Parker 7391 EPDM-P hose is a suction and discharge hose constructed with:
- A peroxide-cured EPDM tube
- Multiple textile reinforcement plies
- An integrated wire helix
- A smooth wrapped synthetic rubber cover
Parker states that the hose uses the same highly engineered peroxide-cured EPDM tube material found in the company’s existing 7390 Series, helping provide increased fluid purity for modern cooling systems.
The hose is also manufactured using halogen-free materials and carries a UL94 V-0 flame resistance rating.
Designed for Data Centers and High-Flow Cooling Systems
As AI computing, hyperscale data centers, and liquid cooling systems continue to expand, cooling infrastructure requirements are changing rapidly. Larger coolant loops and centralized cooling architectures increasingly require hoses capable of handling:
- Higher flow rates
- Vacuum service
- Elevated thermal stability
- Flame-resistant installation environments
The 7391 Series addresses these requirements with full vacuum capability (28″ Hg), a 150 PSI working pressure rating, and a temperature range from -40°F to +212°F (-40°C to +100°C).
Parker specifically notes that the hose is intended for use in:
- Data centers
- Large CDUs
- Facility cooling systems
- DI water cooling loops
- Glycol-based thermal management systems
Phase 1 Launch Sizes
The initial launch includes three large-diameter hose sizes:
| Parker Part Number | Hose ID | Max Working Pressure | Minimum Bend Radius |
|---|---|---|---|
| 7391-2000100 | 2″ | 150 PSI | 7″ |
| 7391-3000100 | 3″ | 150 PSI | 10″ |
| 7391-4000100 | 4″ | 150 PSI | 22″ |
How is the 7391 EPDM-P Hose Different from 7390 EPDM-P?
Parker’s EPDM-P thermal management hose family now includes both the established 7390 Series and the new 7391 Series. According to Parker, both product families use the same peroxide-cured EPDM tube compound engineered for cooling applications requiring high fluid purity.
Parker 7390 EPDM-P Hose
The existing 7390 Series is generally positioned for applications where flexibility and tighter routing are important. Parker references the 7390 tube construction directly in the 7391 launch announcement.
Typical uses include:
- Liquid cooling systems
- Tight routing installations
- Equipment-level coolant plumbing
- Flexible thermal management connections
Parker 7390 EPDM-P Hose
The new 7391 Series is optimized for:
- Larger flow capacity
- Main coolant distribution runs
- Facility piping transitions
- Large CDUs
- Data center infrastructure
Unlike highly flexible coolant hoses, the 7391 design incorporates a wire helix and multi-ply construction to support suction and discharge service in larger diameters.
Key Features of Parker 7391 EPDM-P Hose
Peroxide-Cured EPDM Tube
Peroxide-cured EPDM compounds are commonly selected for cooling applications requiring:
- Heat resistance
- Long service life
- Compatibility with water and glycol coolants
- Improved cleanliness and fluid purity
UL94 V-0 Flame Rating
The UL94 V-0 flame resistance rating makes the hose suitable for installations where fire performance is important, including modern data center and electronics cooling environments.
Full Vacuum Capability
The integrated wire helix reinforcement allows the hose to maintain structural integrity under suction conditions with full 28″ vacuum capability.
Applications for Parker 7391 EPDM-P Hose
Potential applications include:
- AI and hyperscale data center cooling
- CDU supply and return lines
- Industrial process cooling
- Glycol circulation systems
- Facility thermal management infrastructure
- High-volume coolant transfer systems
- DI water cooling systems
The Phase 1 launch includes the following Parker part numbers:
- 7391-2000100
- 7391-3000100
- 7391-4000100
