The best water supply line depends on the fixture and the connection sizes: toilet connectors typically use a 7/8-inch ballcock fitting, while faucet lines vary. These picks include flexible stainless-steel-braided connectors and a bendable brass faucet riser. Eastman’s 12-inch line suits a short toilet connection, its 16-inch model offers more reach, and the Westbrass riser is for buyers who specifically want brass tubing. Check both ends and measure the route before choosing.
| Product | Best for | Key connection or size |

| Eastman 12-Inch Toilet Connector | Short toilet connections | 7/8-inch ballcock x 3/8-inch compression |
| Westbrass Brass Riser | Brass faucet tubing | 3/8-inch x 20-inch; two-pack |
| Eastman 16-Inch Toilet Connector | Extra toilet-line reach | 7/8-inch ballcock x 3/8-inch compression |
| HIGHCRAFT 12-Inch Toilet Line | Flexible toilet installation | 3/8-inch compression x 7/8-inch ballcock |
| PROCURU 24-Inch Faucet Connectors | Longer faucet connections | 3/8-inch compression x 1/2-inch FIP |
Eastman 12-Inch Flexible Toilet Connector
This Eastman connector is best for a toilet where a 12-inch flexible hose can reach from the shut-off valve to the tank. Its ends are 7/8-inch ballcock and 3/8-inch compression, so verify those sizes before ordering.
The hose has a PVC core, multi-filament nylon reinforcement, clear vinyl outer shell, and grade 304 braided stainless-steel exterior. Full-flow brass barbs and nickel-plated solid-brass hex nuts are specified. The maker describes the line as designed to resist kinking and crimping, with installation that does not require soldering, glue, or crimping.
Choose this if you need a short toilet connector with clearly specified fittings. Limitation: its 12-inch length may not reach installations that need a longer route.
Westbrass 20-Inch Brass Faucet Risers
This two-pack is best for buyers seeking brass faucet supply tubing rather than a braided flexible hose. Each riser is 3/8 inch by 20 inches and is made from annealed lead-free brass. The product description says the tubing can be bent with a tube bender or trimmed for routing behind a fixture.
The bullnose end attaches to a sink faucet using a Brunswick nut. Choose this if you want brass risers and can shape tubing to fit the space. Limitation: the Brunswick nut is not included, and this product is not a ready-to-install braided hose.
Eastman 16-Inch Steel-Flex Toilet Connector
This Eastman model is best when a toilet needs more reach than a 12-inch line provides. It connects a tank to a shut-off valve with a 7/8-inch ballcock inlet and 3/8-inch compression outlet.
Its construction includes a PVC core, nylon reinforcement, vinyl outer layer, and stainless-steel braided jacket. Full-flow brass barbs and compression fittings are designed for setup without soldering, adhesives, or special tools. Choose this if the measured route calls for 16 inches and the fittings match your toilet and valve. Limitation: it is a toilet connector, not a faucet line; confirm the endpoint sizes before purchase.
HIGHCRAFT 12-Inch Braided Toilet Line
This line is best for a compact toilet connection where flexibility is helpful in a tight space. It has a 12-inch length, a 3/8-inch compression connection, and a 7/8-inch ballcock connection. The reinforced stainless-steel braid is described as resisting kinks and crimps.
The listing identifies a PVC inner tube as lead-free and NSF/ANSI 61 compliant. Choose this if you want a short braided toilet hose with those stated material details. Limitation: the fixed 12-inch length and toilet-specific ballcock fitting may not suit faucet connections or longer routes.
PROCURU 24-Inch Faucet Hose Connectors
This two-pack is best for faucet installations that need a longer 24-inch connector. Each line is intended for hot or cold water and has a 3/8-inch compression inlet for a supply stop valve and a 1/2-inch female iron pipe outlet for a faucet.
Choose this if your faucet uses those specific fittings and the longer length suits the route. Limitation: these are faucet connectors, not toilet lines; they do not list a 7/8-inch ballcock fitting. The supplied information does not specify construction materials beyond braided stainless steel.
Buying Guide: How To Choose A Water Supply Line
Which fittings should I check?
Match both ends to the fixture and shut-off valve. Toilet connectors in this selection use a 7/8-inch ballcock fitting and a 3/8-inch compression fitting. Faucet lines may instead use a 1/2-inch FIP outlet. Do not assume that lines with similar lengths have interchangeable ends.
Should I choose brass tubing or a braided hose?
Choose a brass riser when you specifically want rigid-style brass tubing that can be shaped with a tube bender. Choose a braided hose when a flexible connector better fits the route. The Westbrass product is a brass riser, while the Eastman, HIGHCRAFT, and PROCURU options are braided connectors.
How do I select the right length?
Measure the path between connection points and allow for a natural curve rather than stretching a line tightly. Compare the measurement with the listed 12-, 16-, 20-, or 24-inch size. For the Westbrass riser, account for bending or trimming and the required faucet nut.
What material details matter?
Review the listed core, braid, and fitting materials alongside the connection dimensions. The products have different constructions, and a brass fitting or brass riser is not the same as a hose made entirely from brass. Use the product’s stated specifications to compare like with like.
Frequently Asked Questions
Are brass supply lines flexible?
Some brass tubing is bendable, but it is not the same as a braided flexible hose. The Westbrass riser can be bent with a tube bender; the other listed lines use flexible hose construction.
Can I use a faucet connector for a toilet?
Only if its fittings match the toilet and shut-off valve. The PROCURU connector has a 1/2-inch FIP faucet outlet, while the listed toilet lines use a 7/8-inch ballcock fitting.
Is a 12-inch line enough?
It is enough only if the measured connection route fits that length without pulling the line taut. Measure before selecting a 12-inch connector.
Does the Westbrass riser include its faucet nut?
No. Its product details state that the Brunswick nut is not included, though one comes with most faucets, according to the listing.
