Dreyoo 12 Pack 16 Inch Toilet Water Supply Line, 3/8" Comp x 1/2" FIP Faucet Hose Connector, Stainless Steel Braided Faucet Supply Line Extension, with 2 Wrenches and 2 Sealing Tapes

I keep a small stash of plumbing consumables in my shop, and supply lines are near the top of that pile. The Dreyoo 16-inch supply line kit has earned a permanent spot there after several installs across bathrooms and kitchens. It’s a straightforward bundle—twelve braided lines with two compact wrenches and two rolls of tape—but the execution is what makes it worth using.

What’s in the box and first impressions

The kit includes:
- 12 stainless-braided supply lines, each 16 inches long, 3/8-inch compression x 1/2-inch FIP
- 2 small adjustable wrenches
- 2 rolls of sealing (PTFE) tape

Each hose arrives individually bagged to keep the ends clean and the braid scuff-free. The fittings are neatly machined with crisp hexes that take a wrench well, and the stainless braid is tight and even with no loose wire ends. The swivel nuts turn smoothly on their seats, and the preinstalled washers sit squarely. It’s a simple thing, but I appreciate consistency when I’m installing multiples in one go.

The included wrenches are compact and light. They’re not shop-grade replacements, but they’re genuinely useful in tight quarters under a sink where a full-size wrench is awkward. If you’re a homeowner with limited tools, they’ll get the job done without chewing up fittings.

Build quality and materials

Each line uses an EPDM rubber inner tube and a 304 stainless steel braid. The EPDM core is flexible and resilient; it bends around cabinet obstructions without feeling spongy or collapsing. The 304 braid provides the right blend of corrosion resistance and stiffness. Crimps at both ends are uniform and fully seated—something I always check because sloppy crimping is where budget lines tend to fail.

Over a few weeks of use, I pressure-checked a handful of installs and cycled shutoff valves to simulate typical use. No weeping at the nuts, no seepage through the crimp, and the nuts held torque after a day and again after a week. That’s what I expect from a decent braided line, and these met the mark.

Installation experience

As far as installs go, these were uneventful in the best possible way:
- The 3/8-inch compression ends engaged cleanly with standard angle stops. The ferrule bit properly and didn’t wander.
- The 1/2-inch FIP swivel ends sealed against faucet shanks with the preinstalled flat washers—no hunting for replacements.
- The 16-inch length reached cleanly from the stop valves to most faucet inlets on standard vanities without needing to arc into awkward loops.

If you’re new to this, a few practical notes:
- Hand-tighten the swivel nuts until they seat, then give a cautious quarter-turn with a wrench. Over-tightening can deform the washer and cause leaks later.
- PTFE tape is not necessary on compression fittings or on the 1/2-inch FIP swivel that seals against a flat washer. Use tape only on tapered pipe threads (NPT), which these lines don’t use. The kit includes tape, but don’t apply it reflexively.
- After pressurizing, check for drips, then recheck an hour later and again the next day. A tiny weep at a new washer often stops with a gentle snug.

The bend radius is forgiving, and the lines resisted kinking even when I had to route around disposal housings and crowded trap assemblies. Under a wall-hung sink with a tight apron clearance, the compact nuts and short ferrules were a help.

Fit and compatibility

This is the one area where you should pause before you buy in bulk. The lines are 3/8-inch compression on one end and 1/2-inch FIP on the other. That’s a common pairing for many faucets: 3/8-inch compression at the shutoff valve and 1/2-inch female swivel to the faucet shanks.

Toilets are another story. Many U.S. toilets use a 7/8-inch ballcock connection at the tank, not 1/2-inch. If your fill valve uses 7/8-inch, these won’t fit without an adapter—and I wouldn’t bother with adapters for a component this inexpensive. That said, there are fill valves and international fixtures that do use 1/2-inch connections, and in those cases these lines work fine. Bottom line: verify both ends on your fixtures before you commit to a 12-pack.

Also consider length. Sixteen inches covers most under-sink runs, but if your stop valves are low or offset, you might need 20-inch or 24-inch lines. I’d rather keep a couple longer lines around than force a tight curve.

Performance and durability

In use, water delivery felt unrestricted. The inner diameter is in line with standard braided lines, and I didn’t see any perceptible drop in flow at the tap after swapping older hoses. The EPDM core has good memory—it flexed without developing a twist that fights you during tightening.

I checked the nuts and crimps after a week and again after a month on two high-use bathroom sinks. No looseness, no oxidization at the braid, and the washers didn’t cold-flow or creep. That’s what I want in a line: install it, pressure test it, forget about it.

The only minor nit: the included PTFE tape is the thin-gauge variety. It’s fine for emergency use on actual tapered pipe threads, but most of these installs don’t call for it, and pros will likely reach for a denser tape when it’s needed elsewhere. The tape is not a drawback; it’s just not a premium add-on.

Value for quantity

Buying supply lines one at a time at a home center adds up fast. This kit’s appeal is that you get a uniform batch of lines that behave the same, thread the same, and torque the same. For property managers, multi-bath remodels, or DIYers working through a whole house, that consistency saves time and reduces callbacks.

The inclusion of two small wrenches is a thoughtful touch. I ended up leaving one in a go-bag with a flashlight, a rag, and a small tube of plumber’s grease. It’s not the tool I’d use to break a stuck stop valve free, but for tightening these swivel nuts in a cramped vanity, it works.

Where it excels

• Multi-fixture projects where you want identical lines with predictable fit
• Faucet installations using 1/2-inch shanks and 3/8-inch stop valves
• Tight spaces that benefit from compact nuts and a forgiving bend radius
• Stocking a maintenance kit with individually bagged, ready-to-use lines

Limitations to note

• Toilet compatibility is not universal. Many tanks require 7/8-inch ballcock connectors; these lines are 1/2-inch FIP.
• The 16-inch length won’t reach every scenario, especially offset or low-mounted stops.
• The included tape is unnecessary for most connections these lines make and isn’t a substitute for proper washers or correct torque.

Practical tips

• Before ordering, check your fixture and shutoff valve thread types and measure the required length with a string.
• Replace aged lines proactively when you see corrosion, mineral buildup at joints, frayed braid, or bulging near crimps.
• Hand-tight, then quarter-turn is a safer starting point than reefing on the wrench. Recheck after pressurizing.

Recommendation

I recommend the Dreyoo 16-inch supply line kit for anyone outfitting multiple faucets or maintaining a small inventory for ongoing work. The build quality is solid—clean threads, tight braid, reliable EPDM core—and the preinstalled washers make for quick, leak-free installs. The compact wrenches are genuinely handy in cramped spaces, and the consistency across the batch makes repeat work faster.

Just be sure the connections match your fixtures: these shine on faucet hookups and select 1/2-inch toilet or appliance inlets, but they’re not a universal toilet solution in the U.S. If you need 7/8-inch ballcock connectors or longer runs, look for the appropriate lines. For everything that fits the 3/8-inch compression to 1/2-inch FIP pattern, this kit is a reliable, cost-effective staple.
