Selection and installation notes
- Use PTFE tape or a thread sealant; do not over-tighten stainless threads, as this can cause galling (cold welding).
- Do not scratch the conical seat faces; clean them before assembly.
- Choose grade 316 where sea water, salty environments or chloride cleaning chemicals are present.
- 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.
