Selection and installation notes
- Both ends are male threaded; the parts to be connected must have female threads.
- Use PTFE tape or a thread sealant; do not over-tighten stainless threads, as this can cause galling (cold welding).
- For sea water, salty environments and areas where chloride cleaning chemicals are used, choose grade 316.
- AISI 304 is intended for general use; choose AISI 316 for chloride media, sea water and swimming pool applications.
- Direct contact between stainless steel and galvanized or carbon steel can cause galvanic corrosion; use insulation (washers, unions) between different metals.
