DirectFill Hose Assy

INJ-DF DirectFill Hose Assembly – Fast, Reliable Watering for Injector Systems

Efficient, high-volume battery watering made simple. The INJ-DF DirectFill Hose Assembly from Philadelphia Scientific is a powerful, industrial-grade solution for filling Water Injector Systems™ and Spider Injector Systems™. Designed for speed, safety, and convenience, this hose assembly delivers consistent water flow to your battery watering system with minimal setup and maximum reliability.

Whether you're managing a single forklift or a large fleet, the INJ-DF is the ideal tool for streamlining battery maintenance and ensuring optimal electrolyte levels across all cells.

Key Features & Benefits

• Compatible with Injector & Spider Systems: Designed specifically for use with Philadelphia Scientific’s Water Injector and Spider Injector battery watering systems.
• High Output Performance: Includes 18 feet (5.5 meters) of industrial-grade hose for extended reach and fast fill times.
• Built-In Flow Indicator: The Instant Valve Pro features a visual spinner to confirm water flow during operation.
• Inline Sediment Filter: Protects your battery system from debris and contaminants.
• Integrated Pressure Regulator: Ensures safe and consistent water pressure for optimal system performance.
• Easy Installation: Connects to a ¾” NPT plumbing source; an isolation valve is recommended at the source for added control.

How It Works

The INJ-DF DirectFill Hose Assembly is engineered to deliver water from a fixed plumbing source directly to your battery watering system. It connects via a ¾” NPT threaded inlet and includes a pressure regulator to maintain safe operating pressure. The Instant Valve Pro coupling at the output end connects to the INJ-CP coupler on your battery system.

Once connected, water flows through the inline sediment filter, down the 18-foot high-output hose, and into your battery’s watering system. The built-in flow indicator spinner provides visual confirmation that water is flowing properly. The system is designed to be used with a Flow Checker to ensure adequate pressure is being delivered to the battery.

This hose assembly is ideal for facilities with a dedicated water line and is a preferred alternative to mobile watering carts when a fixed solution is available.
