Buying Guide
- Material safety: Look for lead-free copper and NSF-61 certification when the fittings will carry drinking water.
- Connection type: Sweat/solder vs. threaded MNPT/NPT; choose based on existing pipe ends and installation preferences.
- Compatibility: Verify pipe type (Type M, L, or K) and nominal diameter to ensure a proper seal and fit.
- Pressure tolerance: For high-pressure systems, prefer fittings with robust copper composition and precise threading.
- Installation ease: Sweat fittings require heat for bonding; threaded options may simplify future disassembly.
- Packaging: Bulk packs are cost-effective for large installations; singles or smaller packs suit repairs.
Frequently Asked Questions
- Q: Are these fittings safe for drinking water? A: Look for lead-free copper and NSF-61 certification to ensure suitability for potable water.
