Boshart NIPBR No-Lead Brass Nipple, Threaded
The Boshart NIPBR is a no-lead brass nipple line built for rough-in plumbing connections where a durable, corrosion-resistant fitting is required between two threaded pipe ends. Machined from solid brass and certified no-lead, this nipple series is suited for potable water rough-in applications and general plumbing connections where a plumber or contractor needs a reliable threaded extension piece. The NIPBR family is available in trade sizes from 1/8" up to 2" and overall lengths ranging from approximately 2-1/2" to 5-1/2", giving installers a wide selection of threaded extension lengths to bridge fittings, valves, and fixtures behind the wall or under the floor. Regardless of the specific size selected, every NIPBR nipple shares the same solid brass, no-lead construction and male-threaded connection style, making it a dependable choice for both residential and light commercial rough-in work.
Key Features
- Trade Size Range: Available from 1/8" up to 2" nominal pipe size to match standard threaded pipe connections in rough-in plumbing runs.
- Length Range: Overall lengths from approximately 2-1/2" to 5-1/2" across the series, providing a defined extension between two fittings or fixtures for whichever run length the job requires.
- Durable Construction: Solid brass material offers strong resistance to corrosion in plumbing service, making it a dependable choice behind the wall or under the floor.
- No-Lead Compliant: Manufactured to no-lead specifications across every size in the series, appropriate for potable water rough-in connections.
- Threaded Connection: Male threaded ends allow each nipple to mate directly with standard threaded fittings, valves, or fixtures common in trade plumbing installations.
- Rough-In Ready: Designed for installation by professional plumbers and contractors as part of a larger supply or distribution run.
- Consistent Series Design: Every size option in the NIPBR line shares the same brass alloy and no-lead compliance, so switching lengths or diameters does not change the material or connection quality.

Boshart NIPBR18X3NL – Frequently Asked Questions
1) What sizes and lengths do the Boshart NIPBR brass nipples come in?
The NIPBR brass nipple line runs 1/8 inch through 2 inch trade size, with overall lengths from 2-1/2 inches up to 5-1/2 inches. The orderable size-and-length combinations are 1/8 x 3, 1/8 x 3-1/2, 1/8 x 4-1/2, 1/8 x 5, 1/8 x 5-1/2, 3/8 x 4-1/2, 3/8 x 5-1/2, 1-1/4 x 2-1/2, 1-1/4 x 3-1/2, 1-1/4 x 4-1/2, 1-1/4 x 5, 1-1/4 x 5-1/2, 1-1/2 x 4-1/2, 1-1/2 x 5-1/2, 2 x 2-1/2, 2 x 4-1/2 and 2 x 5-1/2 inches. Not every length is offered in every diameter, so pick the pair that matches the run.
2) Can I use a Boshart NIPBR brass nipple on a potable water line?
Yes. The NIPBR nipples are no-lead compliant brass, which is what makes them acceptable for potable water rough-in, supply connections and fixture stub-outs. That is the reason to reach for these rather than a plain brass or standard steel nipple on a drinking water run.
3) Are both ends of these Boshart nipples male threaded?
Both ends are male threaded, so a NIPBR nipple mates directly into female threaded fittings, valve bodies, unions or fixture inlets. It is an extension piece between two female ports, not a coupling, so if you need to join two male pipe ends you want a coupling or union instead.
4) What thread type do these brass nipples use, and do I still need thread sealant?
These are tapered pipe threads, the standard NPT male thread that threaded brass, iron and steel plumbing fittings use, so a NIPBR nipple screws into any standard female NPT port of the same trade size. Tapered pipe thread is a sealing thread, but it still needs pipe dope or PTFE tape on the male threads to make a leak-free joint, and neither is supplied with the nipple.
5) Why choose a brass nipple over a galvanized steel one for a rough-in?
Brass resists corrosion better than steel in wet plumbing service, which matters for a fitting buried behind a wall or under a floor where you cannot get back at it. The other reason is the no-lead certification: on a potable water run, a no-lead brass nipple is the code-conscious choice. Galvanized still has a place on non-potable and mechanical piping where cost drives the decision.
6) Is the stated length the whole nipple including the threads?
Yes, the second figure in each NIPBR size is the overall length of the nipple end to end, threads included, ranging from 2-1/2 to 5-1/2 inches. Remember that once it is threaded into fittings on both ends, the exposed face-to-face gap you actually gain is less than that overall figure, so allow for thread engagement when you lay out the run.
7) Can I standardize on one nipple series across a building's plumbing if I need several different sizes?
Yes, that is a reasonable way to buy them. Every size in the NIPBR group uses the same no-lead brass alloy and the same male threaded connection, so moving between a 1/8 inch short piece and a 2 inch extension does not change material, lead status or joint style. For an MRO or multi-family stockroom that means one fitting family covers the small gauge and large gauge threaded extensions.
