Stenner 3/8" Injection Check Valve Assembly (Model UCINJ38)

The Stenner UCINJ38 is a genuine factory replacement injection valve designed for Stenner metering pumps configured with 3/8" discharge tubing. This critical component serves as the final delivery point into your water system while acting as a robust back-check valve. Its internal Santoprene duckbill design allows chemical to flow into the line while instantly sealing against system pressure to prevent water from backing up into your pump and chemical tank.

Product Features:
- Connection Size: 3/8" OD Tubing (Quick-Connect style) x 1/4" MNPT (Male Pipe Thread) Injection Point.
- Materials: Durable housing with a chemical-resistant Santoprene duckbill check valve.
- High-Flow Compatibility: Designed for pumps utilizing larger 3/8" tubing for increased volume or reduced line friction.
- Application: Compatible with the Stenner Classic Series (45/85/100/170), SVP Series, and Econ Series when fitted for 3/8" lines.
- Pressure Rating: Rated for reliable operation in systems up to 100 PSI.

Why Use the UCINJ38?
Maintaining a functional injection valve is essential for system safety. A worn check valve can allow system water to dilute your chemical tank or cause an overflow. Stenner recommends replacing the injection valve regularly to ensure a tight seal and prevent mineral clogging at the injection point.
