Boshart NIPGL Galvanized Steel Pipe Nipple, Threaded Rough-In Fitting

The Boshart NIPGL Galvanized Steel Pipe Nipple is a threaded rough-in fitting built for plumbers and contractors who need a dependable, code-shop-standard connector for galvanized pipe runs. This nipple family is machined from galvanized steel with male pipe threads on both ends, and is available across a wide range of nominal pipe sizes and overall lengths to fit rough-in plumbing, mechanical, and utility applications. Each nipple threads directly into fittings, valves, and equipment ports to extend or connect galvanized piping without the need for additional adapters. The galvanized coating provides corrosion resistance for the threaded steel body, making this nipple a solid choice anywhere a short, rigid, threaded connection is needed between fittings on a galvanized system.

Key Features

  • Size Range: Offered in a broad range of nominal pipe sizes and overall lengths to match standard galvanized pipe and fitting connections for the specific rough-in application.
  • Durable Construction: Galvanized steel body resists corrosion and rust for longer service life in rough-in plumbing and mechanical applications.
  • Threaded Connection: Male pipe threads on both ends allow direct connection into female-threaded fittings, valves, and ports without additional adapters.
  • Rigid Fitting: Solid steel construction provides a rigid, dependable connection point for galvanized pipe systems where flexibility is not required.
  • Consistent Sizing: Manufactured to consistent thread specifications across the size range for predictable fit-up and ordering.
  • Rough-In Ready: Designed as a code-shop-standard connector for behind-the-wall and under-the-floor rough-in work.

Technical Specifications

  • Material: Galvanized Steel
  • Connection: Threaded (MIP), both ends

Boshart NIPGL18X7 – Frequently Asked Questions

1) Are both ends of the Boshart NIPGL pipe nipple male threaded?
Yes, the NIPGL galvanized nipple carries male pipe thread (MIP) on both ends, so it screws straight into female-threaded fittings, valves, and equipment ports with no adapter or bushing in between. That is what makes it the standard part for extending a galvanized run or spacing a valve off a fitting.
2) Can I use a galvanized steel nipple on a copper or PEX system?
Not directly. The NIPGL is a rigid galvanized steel nipple with pipe threads on both ends, meant to tie into female-threaded iron or galvanized fittings and valves. To reach copper or PEX you need a threaded transition fitting on the other side, and joining galvanized steel to copper calls for a dielectric union to avoid galvanic corrosion at the joint.
3) How do I pick the right pipe nipple size for a rough-in?
Two numbers decide it: the nominal pipe size, which has to match the thread size of the fittings or valve ports you are screwing into, and the overall length of the nipple, which sets how far the connection reaches. The NIPGL family is offered across a broad range of both, and each size is its own part number (for example NIPGL4X4 or NIPGL3X5), so order by the size and length combination you need rather than by the family alone.
4) What is a Boshart NIPGL nipple made of, and will it hold up in a damp wall cavity?
The body is galvanized steel, and the zinc coating is there specifically to resist corrosion and rust on the threaded steel. That is why it is the usual choice for behind-the-wall and under-floor rough-in on galvanized systems, and for repair sections in existing galvanized runs.
5) Is the Boshart NIPGL a close nipple or does it give me a run of length?
It is a cut-length nipple, not a close nipple. The family runs in graduated lengths, so there is threaded pipe between the two threaded ends rather than thread running end to end. If you need two fittings pulled up tight against each other, a close nipple is the part for that job, not a longer NIPGL length.
6) Is a rigid steel nipple the right part, or should I use a flexible connector?
Use the NIPGL where you want a solid, non-moving connection: extending a galvanized run, spacing a valve, or landing an equipment port. It is rigid steel with no give. If the connection has to absorb vibration or slight misalignment, such as at a pump or a water heater, a flexible connector is the better part and a rigid nipple is the wrong call.
7) Do I need dope or tape on a galvanized nipple, and will it seal without it?
Tapered pipe threads seal on the thread engagement, but a galvanized steel nipple still needs pipe dope or PTFE tape on the male threads to get a reliable water-tight joint and to keep the threads from galling as you tighten. The nipple itself ships as a bare threaded fitting, with no sealant or gasket included.
8) Is this Boshart nipple suitable for commercial plumbing and mechanical piping, not just residential?
Both. The NIPGL galvanized nipple is catalogued for plumbing use and is applied in residential and commercial rough-in, galvanized run extensions and repairs, mechanical and utility piping, and renovation or new construction work. For a facility standardizing on galvanized threaded pipe, it is the short connector that gets stocked in multiple sizes.
