Why This Nipple Stands Out
Rather than a generic connector, this Smith-Cooper nipple delivers tangible value through its stainless steel composition, lead-free assurance, and a design that supports reliable, repeated sealing under pressure. The 5-inch length offers a practical balance between reach and rigidity, making it a trustworthy choice for skilled installers who demand predictable performance on every project.
Installation Tips
- Prepare threads with compatible sealant or Teflon tape rated for stainless steel and threaded fittings. Ensure even coverage without excess material that could contaminate joints.
- Clean threads before installation to reduce resistance and prevent cross-threading.
- Use two wrenches to tighten—one on each end—to avoid twisting or stressing the nipple.
- Check connections after assembly for leaks and retorque if necessary after a short run-in period.
