The 1/2 in. x 1/4 in. Black Polypropylene Reducing Hex Nipple is a polypropylene hex nipple for extending a threaded connection with wrench flats for easy assembly. Non-metallic polypropylene construction provides excellent resistance to acids, alkalis, chlorine, and most water treatment chemicals — the correct choice for chemical dosing systems, water treatment, and any application where brass or steel pipe fittings would corrode or leach metal into the process fluid.

Key Features
- Polypropylene — resistant to chlorine, dilute acids, alkalis, and most water treatment chemicals
- Non-metallic — no corrosion, no metal leaching into process fluid
- Standard NPT threads for direct replacement of brass or steel fittings in compatible services
- Lightweight — reduces support requirements in large chemical piping systems
- Use PTFE tape on male threads for leak-free assembly — do not over-torque
Common Applications
Chemical dosing and metering systems, water treatment plant piping, pool and spa chemical manifolds, laboratory fluid distribution, irrigation system manifolds, and any threaded piping application requiring chemical-resistant non-metallic fittings.
