Key Features
EPDM Inner Tube for Acid Resistance
Constructed with premium EPDM rubber, the hose offers excellent resistance to phosphoric acid up to 85% concentration. It prevents swelling, cracking, and leaching, ensuring safe handling of corrosive inorganic acids over extended operational cycles.
Textile Reinforcement for Pressure Stability
High-tensile synthetic textile layers provide uniform pressure resistance up to 150 PSI and a burst pressure exceeding 450 PSI. This design ensures safety and performance under pulsed or continuous pressure in process systems.
Non Conductive Tube and Cover Construction
The hose is designed with non-metallic materials, preventing electrostatic discharge during acid transfer—particularly critical in explosive or ATEX-classified zones.
Wide Operating Temperature Range (-40°C to +120°C)
With material stability maintained across a broad thermal range, the hose is suitable for cryogenic environments and high-temperature process lines without loss of flexibility or seal integrity.
Application
► Portable acid transfer units
► Corrosive chemical handling skids
► Acid scrubbing systems
► Acidic waste neutralization setups
