Match the complete hose assembly to the maximum pressure allowed by the pump setup, coating and temperature. DINO-POWER’s listed 1/4-inch, 7.5 m painting hose has a 250 bar working-pressure rating. Burst pressure is a destructive-test value, never an operating limit. Check the actual hose marking and fittings, especially when using higher-pressure pneumatic or hydraulic equipment.
A larger bore can reduce flow resistance, while a smaller hose is easier to handle but can increase pressure loss. DINO-POWER offers sizes including 3/16, 1/4, 3/8 and 1/2 inch. Match bore to the coating, tip demand, pump and route. Send the viscosity and intended length so we can confirm a practical arrangement.
Only with an approved hose configuration for the actual coating and job. The pump’s maximum hose length does not guarantee adequate pressure at the gun in every application. DINO-POWER offers different hose lengths and bores; extensions also need matching pressure-rated couplings. Confirm elevation, bends and gun count before ordering a longer run.


Remove it from service if it shows leakage, bulges, damaged reinforcement, badly worn covering, crushed sections or damaged fittings. Inspect before use and follow the manufacturer’s service limits. DINO-POWER wire-braided and other hose constructions require their specified handling. Do not tape a leak or check it with your hand; relieve pressure and replace the complete approved assembly.
No. The entire spraying setup needs the grounding and continuity checks specified by the equipment and coating instructions. Ask DINO-POWER to confirm the exact hose construction and approved application. Hose color or wire reinforcement alone does not establish the required electrical continuity. Maintain the prescribed pump, gun, container and workpiece grounding, particularly with solvent-based coatings.
Flush with a cleaner compatible with the coating and hose lining, relieve pressure, and coil without kinks or tight bends. DINO-POWER DP-637H uses a listed nylon inner tube and polyurethane cover; check chemical and temperature compatibility for the actual supplied hose. Protect fittings from dirt and impact, and inspect again before reuse. Avoid leaving reactive mixed coating to cure inside.
