Practical installation guidance
For a dependable seal, use appropriate threading compound or PTFE tape on the male NPT threads before tightening. Clean threads before assembly to prevent galling or cross-threading. Tighten to the manufacturer’s recommended torque to avoid over-tightening, which can damage the fitting or pipe threads. When in doubt, consult your local code requirements to ensure compliance for potable-water installations.
What to expect during use
- Consistent, leak-resistant connections thanks to a precision MPT thread on a corrosion-resistant stainless-steel body
- Low-maintenance performance that stands up to routine plumbing tasks and demanding service environments

Care and maintenance
Inspect connections periodically for signs of corrosion or wear, especially in areas with aggressive water chemistry. Rinse and dry fittings after exposure to harsh elements or chemicals, and replace if threads show signs of damage. Stainless steel offers excellent durability, but proper storage—like keeping this nipple bagged—helps preserve its pristine condition until installation.
