Graco 15G781 Coupled Hose

Coupled Hose – Model 15G781

The 15G781 HOSE, COUPLED is a durable, pre‐assembled hose featuring factory-installed couplings designed for reliable fluid transfer in high-performance spray and pump systems. Sized to handle professional applications, this hose ensures consistent flow, secure connections, and minimal downtime.

Applications & Fitment

Engineered for use in industrial spray rigs, line-striping machines, and high-volume coating systems, the 15G781 coupled hose accommodates fluid discharge and return applications requiring factory-matched couplings. It offers a plug-and-play replacement to maintain system integrity and avoid time-consuming field coupling.

Key Specifications

Product Highlights

• Factory-installed coupling ensures proper, leak-resistant connections out of the box.
• Designed for high-duty use to deliver consistent fluid flow in demanding environments.
• Plug-and-play replacement part minimizes installation time and avoids field coupling errors.
• Maintains system integrity and reliability for long-term operation in professional equipment.

Installation & Usage Notes

Before installing the 15G781 hose assembly, depressurize the system and ensure the old hose is safely removed. Align the new hose precisely with the fluid path, insert the coupling into the correct connection and secure per manufacturer torque or clamp guidelines. After installation, gradually pressurize and monitor for leaks, proper flow and secure connection before returning the system to full service.

Maintenance & Care

• Inspect the hose and couplings periodically for abrasion, leaks, or damage to fittings.
• Ensure the couplings remain tight and the hose routing is free from sharp bends or kinks.
• If the coupling shows wear or the hose shows significant damage, replace the assembly to maintain system reliability.
