12-Pack Brass NPT Hex Nipples

This 12-pack supplies 3/4 inch NPT male-to-male brass hex nipples for joining two female-threaded components. The fittings suit plumbing, compressed-air, fuel and general fluid-transfer lines where a straight, rigid connection is required. Solid brass construction resists corrosion and handles temperatures from minus 65 degrees F to plus 212 degrees F. The pack is intended for installers who need multiple identical nipples on hand.

Deep NPT Threads Resist Loosening

Deep-cut National Pipe Taper threads engage fully to create a seal that tightens under pressure and vibration. Brass maintains dimensional stability through repeated thermal cycles between minus 65 degrees F and plus 212 degrees F without galling or stress relaxation. The material’s low magnetic permeability avoids interference with nearby sensors. Each nipple is a single-piece machining, eliminating a potential leak path at a braze joint.

Not For Potable Water Systems

The brass alloy used here is not certified for drinking-water contact, so the nipples must not be installed in potable supply lines. They are also incompatible with compression-style fittings, which rely on a ferrule rather than tapered threads. Buyers needing lead-free or NSF-approved components for domestic water should select a different product.

Questions about this item

Does the brass nipple generate any noise, heat or power draw when installed in a line that runs continuously?

No — it is a passive brass fitting with no moving parts, so it adds no noise, no heat and draws no power.

What pipe or hose must I already have to use these 3/4" NPT male hex nipples?

You need female-threaded pipe or hose ends with matching 3/4" NPT threads; the nipples will not seal on compression or flare fittings.

Will these 3/4" NPT brass nipples thread reliably into older galvanised or black-iron pipe I am keeping in place?

Yes, provided the existing female threads are standard 3/4" NPT; the deep-cut threads on the nipples engage cleanly with vintage pipe threads.
