With lead-free construction and a galvanized finish, this close nipple is built to withstand the demands of both indoor and outdoor installations while keeping safety and reliability front and center.
What it is
A 3-inch, male iron pipe (MIP) close nipple crafted from solid steel and finished in galvanization. Designed for use where two female connections need a short, direct link, this piece offers a compact, durable solution for tight spaces and quick repairs. The lead-free composition makes it suitable for potable water applications, aligning with common plumbing standards while delivering dependable performance in harsh environments.
Why this close nipple stands out
-
Short, strong connection — specifically engineered for tight runs where longer fittings aren’t practical, reducing potential leak points and dead space in the line.
-
zinc-coated durability — the galvanized finish provides corrosion resistance that preserves integrity in moisture, humidity, and exposure to the elements.
-
Lead-free construction — supports safer potable water installations and aligns with safety expectations for residential and light commercial piping.
-
Robust pressure and heat tolerance — rated for up to 200 psi and up to 400°F, making it suitable for a range of hot and cold piping scenarios.
-
Reliable, easy-to-use format — ready for straightforward installation with standard MIP threading on both ends, minimizing compatibility concerns with common pipe sizes.

Ideal uses and practical tips
-
Applications — perfect for connecting two female-threaded fittings in potable-water lines, irrigation setups, or compact industrial piping where space is at a premium.
-
Installation tips — apply an appropriate pipe thread sealant or PTFE tape compatible with metal pipes, tighten by hand and finish with a wrench for a secure seal. Inspect threads for damage before assembly and avoid over-tightening to prevent galling.
-
Assembly considerations — ensure mating fittings are compatible with MIP threads and the galvanized finish; compatible with standard pipe schedules for reliable performance in typical building projects.
-
Maintenance and care — keep the nipple dry when stored; galvanzied coating resists rust in normal service, but avoid prolonged exposure to aggressive chemicals or environments outside listed ratings.
