Meet the Smith-Cooper 3/4 in. MPT stainless steel nipple, a compact, durable connector designed to bridge 3/4" male-threaded fittings with confidence. Built from stainless steel for corrosion resistance and long-lasting performance, this nipple delivers a reliable link in both residential and light commercial plumbing projects.
- — Average Lead Content: Lead-Free, supporting safer connections for potable-water applications.
- — 3/4" with MPT (Male Pipe Thread) for quick, secure mating to female 3/4" NPT fittings.
- — Stainless steel construction provides strength, corrosion resistance, and consistent performance in wet or humid environments.
- — 2-1/2" overall length offers a compact option for tight installations and space-constrained layouts.
- — Carded packaging simplifies stocking on job sites and retail displays for fast picks and replacements.
What makes this nipple a smart choice
This Smith-Cooper nipple focuses on real-world usability. The stainless steel composition resists rust in exposed or high-humidity areas, so fittings stay tight and there’s less worry about recurring leaks. The 3/4" MPT end ensures compatibility with standard 3/4" female threaded components, making it a versatile companion for water lines, compressed-air systems, or irrigation setups where a compact extension is needed.
Ideal use cases
- Extending a short section of pipe to reach essential fixtures without bulk hardware.
- Connecting standard 3/4" female fittings in plumbing tasks, repairs, or DIY projects.
- Repairing or replacing damaged nipples in tight spaces where a longer run isn’t feasible.
- Retrofitting older systems that require corrosion-resistant stainless steel connections.
Practical installation tips
To ensure a reliable seal on stainless steel threaded connections, pair the nipple with an appropriate pipe thread sealant rated for stainless steel and the intended environment. Apply sealant evenly to the male threads before threading into the female fitting, and tighten to the standard hand-tight plus a quarter-turn guideline typical for NPT connections. Inspect connections after initial pressure testing for any signs of seepage.
