Malida 1/4 inch O.D. Length 32.8ft(10 meters) RO Water Tubing, Hose Pipe for RO Water purifiers System,+ 1/4 O.D quick connector 10pcs

Why I reached for this kit

I needed to re-plumb an aging under-sink reverse osmosis setup and add a branch to feed a refrigerator ice maker. I wanted something that would be straightforward to install, safe for drinking water, and flexible enough to adapt to a few routing quirks in my cabinet. The Malida RO tubing kit hit the right notes on paper: 32.8 feet of 1/4-inch OD blue tubing and a genuinely useful assortment of push-fit connectors, including shut-off valves. After installing it across two weekends and living with it for several weeks, I’m impressed by how fuss-free it is—and I’m glad I had the extra fittings on hand.

What’s in the box

The kit includes:
- 32.8 ft (10 m) of 1/4-inch OD blue tubing
- Push-fit connectors: 2 straight, 2 elbows, 2 tees, 2 Y-splitters
- 2 inline shut-off valves

The tubing is billed as non-toxic, odorless, and tasteless. That matches my experience once I flushed the lines. The connectors are standard push-fit style and designed to secure without the usual little blue locking clips. If you’ve used John Guest–style fittings, these will feel very familiar.

Setup experience

Installation is straightforward if you follow a few basics:
- Cut the tubing square. A small tubing cutter or a very sharp utility knife is worth it. Slanted or burred cuts are the number one cause of slow leaks in push-fit systems.
- Seat the tubing fully. I like to mark the insertion depth with a pen (roughly 5/8 inch on most 1/4-inch fittings) so I can confirm it’s fully home.
- Tug test each connection. A firm pull should not release the tube.
- Flush before drinking. I ran a few gallons through the line to clear any manufacturing residue and air.

Under the sink, elbows helped me maintain gentle bends and prevent kinks where space was tight. I used one shut-off valve near the RO outlet for service work and another on the refrigerator branch so I can isolate it independently. The inclusion of both tees and Y-splitters is thoughtful: the tee is handy for adding a perpendicular branch, while the Y creates a more gradual split that can reduce restriction in some layouts.

I didn’t need any specialty tools and only used a cutter, a wrench for the appliance connections, and a towel to catch drips during the swap.

Build quality and leak performance

The tubing has a firm, slightly glossy finish and a wall thickness that feels right for 1/4-inch RO supply lines. It holds a curve without collapsing but still routes easily. I measured and installed about 20 feet across my RO system and the refrigerator run, leaving a few feet in reserve for future changes.

The connectors are consistently molded, and the collets grab positively—there’s tactile feedback when the tube seats past the O-ring. Over several days, I placed dry paper towels under every new connection to sniff out slow weeps. Everything stayed bone dry. I then intentionally removed and re-seated a few connections to check repeatability; no degradation or O-ring nicks.

One question I had was whether the lack of optional locking clips would worry me. After a couple of tug tests and a week of door slams and normal use, I’m comfortable with the hold. If you routinely pull or abrade lines (in a shop environment, for example), you can always add generic retaining clips later, but I didn’t find them necessary for a typical kitchen install.

Taste and odor were non-issues after the initial flush. If you do detect a faint plastic note at first, it’s usually resolved by running more water through the system.

Compatibility and use cases

It’s 1/4-inch OD tubing—the common size for RO systems—so it dropped right into my existing housings, pressure tank, and faucet connections. The push-fit fittings mated with my older connectors without complaint. Beyond RO, 1/4-inch is widely used for refrigerator ice makers, some beverage systems, and small appliances that need filtered cold water. I wouldn’t use this for hot water runs; stick to cold-side, potable-water applications.

A few scenarios where the kit shines:
- Adding a filtered water branch to a fridge or coffee machine
- Re-routing cramped under-sink plumbing with elbows instead of tight hose bends
- Creating service loops and adding isolation valves for easier maintenance
- Splitting a single RO output to serve both a faucet and an appliance

Thoughtful touches

• The included shut-off valves are the unsung heroes here. Being able to isolate the refrigerator line without shutting down the whole RO system is a small quality-of-life upgrade.
• The mix of tees and Y-splitters saves a last-minute run to the store. I used a Y to split the RO output and kept flow adequate on both branches.
• The blue color is standard for cold/filtered lines and makes tracing and troubleshooting simpler.

Where it falls short

• Only 32.8 feet of tubing. That was enough for my setup with a little to spare, but longer runs to a distant fridge might need an extra coil. If you’re spanning floors or going around obstacles, plan your route and measure before you start.
• No angle-stop or appliance adapter. This kit focuses on tubing and push-fit connectors. You may still need a supply valve adapter, faucet adapter, or appliance-specific fitting depending on your plumbing.
• 1/4-inch limitations. It’s perfect for RO and ice makers but not meant for high-flow appliances. Don’t expect it to serve a dishwasher or instant hot water system.
• Inline valves introduce minor restriction. For RO and ice maker feed lines it’s negligible, but if you’re chasing every last ounce of flow, place valves thoughtfully.

Tips for a clean install

• Support long vertical runs with clips or clamps to prevent the weight of water from pulling on fittings.
• Avoid tight bends; if you need a 90-degree turn in a small space, use an elbow instead of forcing the tube.
• Keep the line away from sharp cabinet edges. A small grommet or edge protector where the tubing passes through wood is cheap insurance.
• Label your shut-off valves. A piece of tape marked “Fridge” or “RO” will make future maintenance stress-free.
• Keep a short spare length and one extra straight connector in your toolkit. They solve a surprising number of last-minute issues.

Longevity and maintenance

After several weeks, the install has been stable: no drips, no taste issues, and no need to re-seat any fittings. Push-fit systems like this make filter changes simpler because you can add valves and unions exactly where you need them. I give connections a quick inspection whenever I swap filters and replace any segment of tubing that looks scuffed or kinked. The blue tubing doesn’t yellow or stiffen noticeably under the sink, but I wouldn’t run it in prolonged direct sunlight.

Value

Buying tubing and a mixed bag of quality fittings separately adds up fast. The Malida kit bundles the essentials at a sensible price and, importantly, includes the parts you typically forget (shut-off valves, a couple of elbows). If you’re a DIYer tackling a first-time RO installation or a pro who wants a compact kit for quick fixes, this is easy to keep on hand.

Recommendation

I recommend the Malida RO tubing kit. It’s an easy, reliable way to plumb or expand a household RO system and branch filtered water to a refrigerator or small appliance. The tubing is clean and neutral after flushing, the push-fit connectors hold securely without extra clips, and the assortment—especially the shut-off valves—covers most real-world layouts. While you may need a few supply-side adapters depending on your setup and very long runs will require additional tubing, this kit earns its keep by making the core job painless and by helping you avoid multiple trips for forgotten fittings.
