PROCURU [2-Pack] PROCURU 16-Inch (1.3Ft) x 3/8" Comp x 1/2" FIP Faucet Hose Connector, Stainless Steel Braided Supply Line, Certified Safe

Why I Picked These Lines

I reached for the Procuru 16-inch braided faucet hoses for a straightforward bathroom faucet swap and a later kitchen refresh. I wanted something that would connect a standard 3/8-inch compression shutoff to a typical 1/2-inch IPS/NPSM male faucet shank without fuss, resist corrosion under a sink that occasionally sees cleaners and humidity, and meet current lead-free standards. On paper, these lines check those boxes: 316 stainless braid, nickel-plated brass nuts, NSF/ANSI 61 Annex G compliance, and the exact 3/8” compression x 1/2” FIP pairing most faucets need. In practice, they performed exactly as I hoped.

Build Quality and Materials

The difference I noticed out of the package is the braid. Many off-the-shelf hoses use 304 stainless, which is perfectly serviceable for indoor use; Procuru specifies 316 stainless, which offers better pitting and chloride corrosion resistance. Indoors that may sound academic, but it’s reassuring for coastal environments, homes with salty winter air, or cabinet spaces where bleach-based cleaners are stored. The weave is tight and even, the crimps are clean, and there’s no stray wire fraying at the ferrules.

The nuts are nickel-plated brass, not plastic. Threads were uniform and free of burrs. The 1/2-inch female connector includes the proper captive sealing surface for a straight-thread faucet shank, so you’re not relying on tape to seal tapered pipe—exactly what you want on faucet connections. The 3/8-inch compression end mated cleanly to my angle stops with that familiar metal-on-metal compression seal.

Fit and Compatibility

• Inlet side: 3/8-inch OD compression to a standard faucet shutoff/angle stop. No tape needed or wanted—compression fittings seal on the ferrule and mating surface.
• Outlet side: 1/2-inch FIP/IPS (straight thread) to typical faucet shanks with a gasketed seal. Again, no tape needed; the gasket does the work.

These are not universal for every faucet. Many modern faucets ship with integrated 3/8-inch braided hoses already attached; in that case, these are unnecessary. Some older faucets use different thread formats, and toilets are a different story entirely (7/8-inch ballcock). If your faucet shanks are the usual 1/2-inch IPS/NPSM male, you’re good.

The 16-inch length was perfect for the bathroom where the stops sit directly below the basin. Under my kitchen sink, the layout demanded a longer run; I used these on one side that lined up nicely and opted for a longer hose on the other. As with any supply line, measure the path you plan to take, not just the straight-line distance. Give yourself a gentle loop rather than a taut, straight run.

Installation Experience

Installation was uneventful in the best way:

1. I shut off the stops and relieved pressure at the faucet.
2. I threaded the 1/2-inch end onto the faucet shanks first, hand-tight, then a careful snug with a wrench—just past firm to seat the gasket without crushing it.
3. On the 3/8-inch compression side, I cleaned the valve seat, aligned the hose end, and tightened until resistance increased, then an additional partial turn to seal.

A few practical notes:
- Don’t use thread tape on either end. The seals are gasketed (faucet side) and compression (valve side).
- Start every connection by hand to avoid cross-threading, especially in cramped cabinets where it’s easy to go crooked.
- Avoid tight bends right at the ferrules. A gentle sweep reduces stress on the crimp and the inner tube.
- After pressurizing, wipe each connection dry and check again after a few minutes. I also like a second check after a day in case a gasket settles.

Both sets sealed on the first try. No weeping at the compression joints, and no drips at the faucet shanks. I left them pressurized and checked again the next morning—still dry.

Performance and Everyday Use

There’s not much “performance” to a supply line beyond staying dry and minding its bend radius. These lines do both well. The braid has enough rigidity to hold a loop without collapsing but remains flexible enough to route around disposal housings and trap arms. They don’t transmit noticeable vibration or “water hammer” beyond what I’d expect from any decent braided line.

From a maintenance standpoint, the stainless braid wipes clean, and the nickel-plated nuts haven’t discolored in a humid cabinet. The peace-of-mind piece is the certification: NSF/ANSI 61 Annex G compliance means the wetted metal parts meet lead-free requirements for potable water—table stakes now, but not universal if you’re buying bargain-bin parts.

Durability Expectations

I can’t claim multi-year data from my installs yet, but the ingredients are right: 316 stainless braid, brass/nickel hardware, proper ferrule crimps, and gasketed seals where they belong. I’ve used plenty of 304-braided lines that last a decade or more; with 316, I’d expect at least that, provided you avoid overtightening and don’t force a kink near the ends. As with any braided connector, periodic visual inspection is a good habit—look for rust staining, bulges, or corrosion at the crimps.

Value

Two lines in a pack makes sense for a faucet (hot and cold), and the price-to-quality ratio is strong. Compared to the generic big-box options, you’re getting better alloy spec on the braid and solid machining on the fittings without paying a premium brand surcharge. If you’re doing multiple sinks, buying a couple of these twin packs adds predictable consistency to your installs.

What They Fit—and What They Don’t

Use these if:
- Your shutoff valves are 3/8-inch compression outlets.
- Your faucet has 1/2-inch IPS/NPSM male shanks.
- You need roughly 16 inches of run and can route a gentle loop.

Skip these if:
- Your faucet includes factory-attached supply hoses (most modern pull-down kitchen faucets do).
- Your stops are 1/2-inch IPS male threads (you’d need a different hose end).
- You’re outfitting a toilet or an appliance with non-matching connectors.

If you’re unsure, take a photo of your valve and faucet underside and measure the center-to-center path. A slightly longer hose is better than forcing a tight bend.

Tips for a Clean, Leak-Free Install

• Replace aging stop valves before adding new hoses; a failing stop can leak at the stem even if the supply line is perfect.
• Support the faucet while tightening to avoid twisting the shanks.
• Tighten in small increments and test—overtightening can deform gaskets and ferrules.
• Label hot and cold lines during removal so you don’t cross them on reassembly.

The Bottom Line

Procuru’s 16-inch braided supply lines are the kind of unglamorous component you forget about—because they simply work. The 316 stainless braid is a cut above the usual spec, the nickel-plated brass fittings thread smoothly, and the sealing surfaces are designed for the connections they’re meant to make. In my installs, they measured true to length, routed cleanly, and sealed on the first pressurization without any need for tape or do-overs.

I recommend these lines for anyone replacing or installing a faucet that requires a 3/8-inch compression to 1/2-inch FIP connection. The reasons are straightforward: solid materials, potable-water compliance, easy installation, and dependable sealing at a fair price. Just confirm your thread types and length before you order, and you’ll be set for a quick, dry, and durable connection.
