The Anderson Metals 1/2 in. MPT x 1/2 in. MPT Red Brass Nipple, 3 in. long, is a purpose-built bridge for low-to-medium pressure piping where two female 1/2" fittings need a reliable connect-and-extend solution. Featuring male pipe thread on both ends, this nipple makes quick work of joining brass, copper, or iron systems with precision and confidence.
Why this red brass nipple stands out
-
Precise, compatible threading: 1/2" MPT on both ends (Male Pipe Thread), designed to mate with standard female 1/2" fittings for straightforward installations.
-
Robust long-form connector: 3 inches in length provides the reach you need in tight spaces or to span between components without stressing joints.
-
Low lead content and ANSI certified: Average lead content below 0.25% and ANSI certification offer reassurance for residential and commercial plumbing applications.
-
Red brass construction for reliability: Built from red brass, known for solid mechanical performance, heat tolerance, and corrosion resistance in hot-water and heating applications.
-
Temperature tolerance: Rated to handle temperatures up to 250°F, making it suitable for hot water lines, radiant heating, and other modest-temperature scenarios.
-
Material compatibility: Suitable for brass, copper, and iron pipe materials, expanding its versatility across common piping systems.
-
Single-piece practicality: Sold individually, so you can pick the exact length you need without excess parts.
Typical use cases include joining two female-threaded fittings in residential water lines, extending a hot-water feed in a boiler or radiant heating setup, or repairing a short segment of piping where space constraints demand a rigid, threaded connection. This nipple is especially well-suited for projects where a durable, heat-tolerant connection is required between dissimilar metals (brass, copper, iron) without compromising flow or reliability.
Practical installation tips
- Prepare threads with an appropriate thread sealant or PTFE tape rated for potable water, applying evenly in the direction of assembly to ensure a tight seal.
- Clean both mating threads before installation to prevent debris from compromising the joint.
- Tighten with a compatible wrench until snug, then give a final gentle turn to seat the threads—avoid overtightening which can damage threads.
- After installation, test for leaks using a soapy-water check or a pressure test appropriate for the system.
Choose the Anderson Metals 1/2 in. MPT x 1/2 in. MPT Red Brass Nipple for a dependable, long-lasting connection that respects safety and industry standards. Its low-lead composition, ANSI certification, and compatibility with common piping materials help you complete hot-water and heating projects with confidence, reducing the risk of leaks and service interruptions.
