Super Flexible, Bends Like Rope: The 4" hose has a minimum bending radius of only 101.6 mm (equal to its I.D.), so this lightweight flexible suction hose coils easily for storage and maneuvers effortlessly in tight workspaces.
EPDM Triple-Layer Construction: Smooth EPDM inner tube, polyester fiber + spiral steel wire reinforcement, and abrasion/oil/aging-resistant EPDM cover — a true EPDM water suction hose built for long service life in harsh conditions.
All-Weather Temperature Range: -54°C to +93°C keeps the hose flexible year-round, making it a dependable all weather suction hose for hot water and freezing environments.
150 PSI Working Pressure: Rated 150 PSI working / 450 PSI burst, this heavy duty suction hose resists collapse under medium-duty suction and discharge.
Custom Couplings & Lengths: PUSH ON, crimped or quick couplings in carbon steel, copper, SS304/316/316L; sizes 3/4" to 4", up to 60 m per coil, OEM custom water hose friendly with low MOQ.
Agricultural Irrigation: Large-volume irrigation water transfer on farms and orchards; lightweight and soft for easy dragging and re-coiling in the field.
Construction Dewatering: Construction dewatering for foundation pits and tunnels; large bore for fast pumping, resistant to repeated dragging.
Mining Dewatering: Mining dewatering and slurry transfer; spiral steel wire reinforcement prevents collapse under negative pressure.
Wastewater Transfer: Wastewater transfer in treatment plants; EPDM resists low-corrosion chemicals and cleaning agents.
Industrial Cooling & Slurry: Semi-extraction of cutting fluid, coolant, hot water and pulp; lightweight structure suits mobile pump sets.
Q1: What are the working pressure and flexibility of this 4 inch suction hose? A: It is rated 150 PSI working / 450 PSI burst — a standard heavy duty suction and discharge hose. The minimum bending radius equals the inner diameter (only 101.6 mm on 4"), making it a rare super flexible water hose that coils for storage.
Q2: What temperature range does the EPDM hose handle, and which media can it transfer? A: The operating range is -54°C to +93°C — an all-weather EPDM water suction hose compatible with coolant, hot water, cutting fluid, low-corrosion chemicals, sewage, cleaning agents and pulp.
Q3: Can you customize couplings and lengths? What is the MOQ? A: Yes. PUSH ON, crimped or quick couplings in carbon steel / copper / SS304 / 316; sizes 3/4" to 4" and lengths up to 60 m per coil. MOQ starts from 1 coil for distributors and OEM custom water hose projects; lead time about 2 weeks.
