NIBCO 3/4 in. Sweat X 3/4 in. D FPT Brass 90 Degree Elbow

The NIBCO 3/4 in Sweat X 3/4 in D FPT Brass 90 Degree Elbow is a robust copper-to-thread transition designed to simplify tight spaces and buried installations. With a solder-on copper sweat end and a 3/4 in female pipe thread, this elbow makes it easy to route piping where fixtures and threaded valves meet, without sacrificing durability or reliability.

Why this brass elbow stands out

• Two-end configuration: 3/4 in copper sweat (solder) on one side and 3/4 in female pipe thread (FPT) on the other, enabling quick, secure transitions between copper tubing and threaded fittings.
• Brass construction: Built to withstand corrosion and long-term use in both indoor and underground environments, offering dependable performance in plumbing runs that may be buried or exposed.
• Underground rated: Suitable for buried installations, giving you flexibility for outdoor water lines, underground supply runs, and landscape work.
• NSF listed: Meets recognized standards for safety and quality, giving you confidence in performance for potable or other water systems where approved components are required.
• Lead content under control: Average lead content less than 0.25%, aligning with modern plumbing expectations for safer materials.
• Compact, 1-piece package: Sold as a single piece in bagged packaging, ready to drop into your project without excess bulk.
• Pressure tolerance: Rated for Maximum Working Pressure up to 582, supporting a wide range of residential and light commercial applications.
• Pipes and fittings compatibility: Designed specifically for copper pipe systems, ensuring a reliable sweat connection on the copper side and a precise, threaded connection on the FPT side.

Ideal use cases

• Connecting copper supply lines to threaded valves, spigots, or appliances where a 90-degree turn is required.
• Installing in basements, crawl spaces, or outdoor areas where buried or partially exposed piping is common.
• Retro fits and repairs where you need to convert from a copper sweat run to a threaded component without reworking the entire line.

Practical installation tips

• For the sweat end: clean the copper, deburr the cut, apply flux, and heat with a suitable torch before applying lead-free solder for a tight, leak-free joint.
• For the FPT end: wrap the male thread with Teflon tape or apply an appropriate pipe thread sealant, tightening just enough to seat the connection without over-tightening.
• Plan your layout to avoid stressing the elbow after installation; a slight alignment check prior to soldering and threading helps prevent leaks.
• Always confirm compatibility with nearby fittings and valves to ensure a smooth transition and proper seal across both connection types.
