- Stainless steel construction delivers exceptional resistance to rust and corrosion, enabling longer service life in wet, humid, or outdoor applications.
- Lead-free formulation helps ensure safer connections for potable-water systems and aligns with regulatory expectations for plumbing components.
- 4 in. overall length offers ample thread engagement for a reliable seal and easier alignment in tight or awkward spaces.
- Rated up to 300 psi, making it suitable for a wide range of residential and light-commercial piping tasks.
- Bagged packaging protects the component during shipping and storage, helping maintain its condition until installation.
Ideal use cases
This nipple is well-suited for connecting standard NPT fittings in residential plumbing, outdoor irrigation setups, and light-industrial piping projects where stainless steel and lead-free materials are preferred. Whether you’re repairing a leak, extending a line, or upgrading to a more durable material in a corrosive environment, the 4-inch length and dual 2-inch MPT ends simplify your installation and improve reliability.
Installation tips
- Prepare threads with a clean, dry surface. Use a compatible thread sealant or PTFE tape rated for stainless steel and the fluids in your system.
- Hand-tighten first, then snug with a wrench to avoid cross-threading. Do not over-tighten, as this can damage threads and compromise the seal.
- Inspect for leaks after installation by applying a soap solution or using a leak detector appropriate for the system media.
