STZ Industries 3 in. MIP x 3 in. MIP Black Steel Close Nipple is a compact, durable pipe-fitting solution designed for solid, dependable connections in tight spaces. With MIP (Male Iron Pipe) threads on both ends and a sleek black finish, this close nipple provides a reliable bridge between two female-threaded fittings or other compatible components in your piping system.
Why this close nipple stands out
-
Two identical MIP ends—ensures a straightforward, symmetrical connection where space is limited and alignment matters.
-
3 in. length for compact, low-profile installations where longer nipples won’t fit or would add unnecessary bulk.
-
Black steel finish combines corrosion resistance with a discrete, professional look suitable for exposed or visible piping.
-
Lead-free construction aligns with safety-conscious projects, especially in potable-water applications.
-
Robust steel fabrication provides the strength needed for demanding environments and longer service life.
-
Bagged packaging helps protect the threads and keeps components organized on-site or in stock.
Ideal uses and practical applications
- Plumbing installations where two female-threaded components must be joined in a tight space, such as under sinks or inside wall cavities.
- Gas, water, or other piping systems that permit MIP connections and require a compact, reliable link between fittings.
- Repairs or retrofits where existing components have male-threaded ends that must be bridged efficiently.
- Residential or light-commercial projects where a dependable, uniform 3-inch connection is preferred for consistency and ease of assembly.
Installation tips and best practices
- Always apply an appropriate thread sealant or PTFE tape on male threads before assembly to minimize leaks and ensure a tight seal.
- Clean threads before installing to prevent debris from compromising the connection and to preserve thread life.
- Aim for a snug, not over-tightened, installation to avoid thread damage while maintaining a secure connection.
- Verify compatibility with your system’s materials and local codes, especially when used for potable-water or gas lines.
