1. Product Overview
KRES KP710 EPDM rubber hose is an economical single‑layer fiber‑braided EPDM hose under the KRES brand. Manufactured with peroxide vulcanization technology, it is designed for low‑pressure water‑cooling and pneumatic circuits. Balancing cost‑efficiency, temperature resistance and media compatibility, it is widely applied in general working conditions such as industrial cooling, plant air supply and data‑center liquid cooling, serving as a versatile fluid‑transfer hose.
2. Construction & Materials
The hose adopts a three‑layer composite structure for stable and durable performance:
Inner Tube: Black peroxide‑vulcanized EPDM rubber, complying with ARPM Class C oil‑resistance standard. Resistant to coolant and moisture erosion, with smooth inner wall for low fluid resistance.
Reinforcement: Single‑layer high‑strength synthetic fiber braid, evenly distributing internal pressure and boosting overall pressure‑bearing capacity.
Outer Cover: Weather‑resistant EPDM rubber, available in Black (BK), Red (RD) and Blue (BU). Resists UV and ozone ageing, resisting cracking for long‑term outdoor service.
3. Key Performance Specifications
Size Range: 3/16' ~ 2' (Inner diameter: 4.80 mm ~ 50.80 mm), covering small‑bore pneumatic lines to large‑size liquid‑cooling main pipes.
Pressure Rating: Working pressure 13.8 bar (200 PSI); burst pressure 55.2 bar; 4:1 safety factor for reliable operation.
Temperature Range: -40 ℃ ~ +99 ℃. Maintains good flexibility under extreme temperatures; no brittleness in cold environments and no softening or leakage under high temperature.
Compatible Media: Clean water, water‑glycol mixtures, standard industrial coolants and compressed air. Suitable for most industrial cooling and pneumatic fluids.
4. Core Product Advantages
Color‑coded tubing: Black, red and blue outer covers enable visual identification for supply, return and air lines, simplifying on‑site recognition, inspection and maintenance.
Superior weathering & ageing resistance: EPDM delivers outstanding ozone and UV resistance, resisting cracking and delamination during long‑term service in workshops and data‑center rooms.
Cost‑effective design: Single‑layer fiber‑braided construction streamlines manufacturing for lower cost, meeting general low‑pressure requirements as an alternative to high‑cost multi‑ply hoses.
Oil resistance: Both inner and outer tubes adopt ARPM Class C oil‑resistant formulation, resisting swelling and damage in oily mist workshop environments.
Lightweight & flexible: Low weight and excellent bend performance facilitate routing and installation for CDU units and air‑conditioning water‑cooling pipelines in data centers.
5. Application Scenarios
Recommended Applications
- Data‑center liquid‑cooling systems: CDU units, air‑conditioning water‑cooling circulation pipelines (compatible with DN125 / DN150 large‑bore piping).
- Industrial mold cooling: Cooling water circulation for injection‑molding and die‑casting machines.
- Plant pneumatic systems: General‑purpose compressed‑air transfer lines for workshops.
- Water and air circuits for automated equipment, general machinery and equipment maintenance.
Non‑recommended Applications
Not suitable for heavy‑duty conditions with frequent pressure pulses or continuous severe cyclic bending, which will accelerate fatigue failure of the braided reinforcement.
6. Model Naming Convention
- KP710: Product series code
- XX: Nominal bore size in inches
- RD = Red, BU = Blue, BK = Black. Select suffix for circuit identification.
7. Summary
Featuring wide operating‑temperature range, color‑coded identification, stable pressure performance and high cost‑efficiency, the KRES KP710 EPDM hose satisfies general fluid‑transfer demands for data‑center liquid cooling, industrial water cooling and low‑pressure pneumatics. With material compatibility for coolants, excellent weathering resistance and easy installation, it is the preferred hose for standardized piping in data‑center rooms and industrial facilities.
