Brass Nipple, 1/4x3

The Midland Metal Mfg Brass Nipple in a 1/4" x 3" size is a compact threaded fitting built for the tight, low-flow connections that appear throughout water-treatment plumbing. Machined from solid brass with male NPT threads on both ends, it links valves, gauges, drain lines, and accessory ports with a clean, leak-resistant joint that holds up under everyday system pressure.

Where it fits in your system

At the 1/4-inch pipe size, this nipple is a natural choice for pressure-gauge taps, injector and brine-line runs, small bypass legs, and instrumentation ports on softeners and filtration control heads. The three-inch length gives you enough reach to clear neighboring fittings and make room for a wrench, while keeping the overall run short and rigid. Brass is the preferred material here because it tolerates chlorinated and softened water far better than plain carbon steel, resisting the rust and scale buildup that can gradually throttle narrow passages and choke off flow to gauges or injectors.

• Fitting type: close-tolerance threaded pipe nipple
• Material: durable, corrosion-resistant solid brass
• Size: 1/4" NPT diameter x 3" overall length
• Male threads on both ends for valve and accessory hookups
• Approximate weight: 0.10 lb each
• Ideal for gauge ports, drain taps, and brine-line connections

Installers consistently favor brass for its workability. It threads smoothly, seats reliably with PTFE tape or pipe-joint compound, and stands up to repeated service without galling or seizing the way steel can. The smooth, well-defined threads make a confident seal the first time, so you spend less time chasing slow leaks. Whether you are plumbing a brand-new softener, adding instrumentation to an existing manifold, or repairing a control-valve assembly, this 1/4" x 3" length is the dependable, no-surprises component you reach for again and again. A trusted plumbing-hardware staple from Midland Metal Mfg, it is worth keeping a few on the shelf for both planned installs and unexpected repairs around the water-treatment system.

Maintenance is minimal: brass needs no special care beyond an occasional check of the joint for weeping during routine system service. Should you ever need to break the connection, the corrosion-free threads back out cleanly without the seized, rusted struggle common to ferrous fittings, making future repairs and upgrades far easier.
