Why this STZ nipple stands out
This 1 in. MIP x 1 in. MIP nipple delivers a precise, leak-tight connection between two female-threaded fittings. The 7-inch length strikes a balance between reach and compactness, making it ideal for mid-line splices, equipment hookups, or extending a run where space is limited. The all-steel construction with a protective black finish provides long-lasting strength and resistance to everyday wear, while the lead-free design helps meet current plumbing reliability standards.
Practical uses and scenarios
- Replacing a damaged or worn nipple in residential water, heating, or mechanical systems.
- Bridging a gap between two female fittings in tight utility rooms, basements, or crawl spaces.
- Creating a rigid, permanently-fastened connection in sprinkler, irrigation, or equipment hookup lines.
- Supporting mid-length runs where a longer continuous pipe would be impractical.
Installation tips
- Ensure both thread surfaces are clean and dry before assembly.
- Apply a suitable thread sealant: PTFE tape (3–4 wraps) or a pipe-joint compound rated for steel threads and your medium.
- Tighten with a wrench to a snug fit; avoid excessive torque that could damage threads.
- Only use this nipple within its rated pressure and temperature limits (up to 226 psi and 400°F).
