4 Inch Epdm Lined Phosphoric Acid Hose Chemical Resistant 150 Psi Smooth Bore

4inch Epdm Lined Phosphoric Acid Hose Chemical Resistant 150 Psi Smooth Bore

Kink Resistant Hose for Heavy Duty Acid Transfer
Built for repeated flexing and routing, this hose features a reinforced EPDM core that resists kinks, pressure loss, and wear. Rated for continuous-duty transfer of phosphoric acid. Outer layer resists mechanical abrasion and environmental exposure. Ideal for high-traffic plant use and automated fluid systems.
 

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
