Meet the Smith-Cooper 3/8 in. MPT Stainless Steel 2-1/2 in. L Nipple — a compact, lead-free connection engineered for durability in tight plumbing runs and equipment hookups. With a 3/8 inch male pipe thread (MPT) on one end and a practical 2-1/2 inch length, this stainless steel nipple delivers reliable, corrosion-resistant performance where space is at a premium.
Why this Smith-Cooper nipple stands out
-
Lead-free construction supports safe drinking-water systems and code compliance, giving peace of mind for residential and commercial use.
-
Stainless steel durability resists corrosion, rust, and chemical exposure better than many brass or galvanized alternatives, ideal for moisture, outdoor installs, and challenging environments.
-
Compact 2-1/2" length fits tight installations, appliance connections, boiler rooms, and space-constrained plumbing runs without sacrificing strength.
-
3/8" MPT end provides a secure, standardized male connection that mates with compatible female fittings, valves, and fixtures.
-
Bagged packaging helps protect the part during transit and on-site handling, keeping threads clean for easier assembly.
Ideal uses and scenarios
- Connecting a valve to a supply line in compact spaces such as under sinks, behind appliances, or in boiler rooms.
- Extending or repairing small-diameter piping runs where a sturdy stainless steel nipple is preferred over softer metals.
- Water and light-duty plumbing tasks in residential, commercial, or light industrial settings where lead-free materials are required.
- Replacement for worn or damaged 3/8" MPT connections in less accessible service areas, thanks to its robust stainless steel construction.
Installation tips
- Prepare threads with a suitable thread sealant rated for metal pipes (follow manufacturer recommendations).
- Hand-tighten first, then snug with a wrench—avoid over-tightening to prevent galling on stainless threads.
- Inspect threads for damage before assembly; replace if threads are compromised to ensure a leak-free connection.
