How to choose
- Pressure class: 150# malleable fittings are the standard class for general plant piping; 300# extra heavy fittings suit higher-pressure or heavier-duty lines. Check the maker’s rating for your size, media and temperature.
- Not for gas: use black iron for fuel gas lines; galvanized is for water, air and drain service. Check local codes.
- Size and ends: match nominal pipe size and check male vs. female NPT ends; street elbows have one male end to save a nipple.
- Don’t mix metals carelessly: joining galvanized directly to copper or brass can cause galvanic corrosion; use a dielectric union.
- Sealing: use PTFE tape or a pipe thread sealant rated for the service.
