KleerBlue 744048 RSV Basic Dispense Coupler

This reusable stainless steel valve is a spring-actuated coupler that's designed to make dispensing Diesel Exhaust Fluid (DEF) clean and efficient. When you disconnect the coupler, it closes automatically to prevent spills, keeping the DEF inside the hose. Here are the key features of the valve: Spill-Free Design: It works with a corresponding RSV Valve (sold separately) that screws into a drum or tote, creating a completely closed system. Easy Connections: The coupler has a 3/4" barb that connects to the suction side of your pump hose. Stable Flow: It includes a built-in breather and an integrated low-vacuum break umbrella check valve to ensure a smooth, stable flow of DEF during dispensing. Durability: Made with heavy-duty stainless steel, the coupler is built to be durable and last a long time. Compatibility: This valve is part of a proprietary 4-pin keyed system for DEF and is compatible with both 55-gallon drums and 275/330-gallon totes (IBCs). Locking Mechanism: A locking bale handle helps secure the connection.
