Stenner UCDBINJ 1/4" Injection Valve | Genuine Replacement Part

Stenner 1/4" Injection Check Valve Assembly (Model UCDBINJ)

The Stenner UCDBINJ is a genuine factory replacement injection valve designed for use with all Stenner metering pumps using 1/4" discharge tubing. This dual-purpose fitting acts as the final injection point into your water line while serving as a critical back-check valve. Its integrated spring-loaded diaphragm prevents pressurized system water from flowing backward into your chemical feed line and tank—protecting your equipment from damage and overflow.

Product Features:
- Connection Size: 1/4" OD Tubing Connection x 1/4" MNPT (Male Pipe Thread) Injection Point.
- Materials: Durable Santoprene duckbill check valve for superior chemical resistance and a long-lasting seal.
- Compatibility: Fits Stenner Classic Series (45/85/100/170), SVP Series, and Econ Series pumps.
- Function: Prevents backflow and provides a point of injection for chlorine, acid, and other water treatment chemicals.
- Pressure Rating: Rated for systems up to 100 PSI.

Maintenance Tip:
The injection valve is the most common point of scale build-up in water treatment systems. To prevent pump strain and ensure accurate dosing, Stenner recommends inspecting and cleaning the UCDBINJ every time you replace your pump tube.
