TAILONZ PNEUMATIC 1/4 Inch od Push to Connect Fittings Pneumatic Fittings Kit 10 Spliters+10 Elbows+10 tee+10 Straight

Why I reached for this kit

I needed to clean up a small shop air manifold and add a few lines for a benchtop sander, a blow gun, and a tire inflator. I also had a compact pneumatic project on a CNC router where I wanted to keep runs tidy and modular. For both jobs, I grabbed the Tailonz 1/4-inch push-to-connect kit—and ended up using far more of it than I expected. It’s a straightforward assortment (10 straights, 10 elbows, 10 tees, 10 Y splitters), but the mix is balanced enough that I could plan the layout, route tubing neatly, and still have spares for future tweaks.

What’s in the box

• 40 plastic push-to-connect fittings
• Styles: straight, elbow, tee, and Y splitter (10 of each)
• Size: 1/4-inch OD tubing only
• Rated for air service, 0–145 psi, 0–60°C (32–140°F)

There are no threaded adapters, valves, or reducers here—just in-line connectors. If you need to transition to NPT or BSP threads, you’ll need separate adapters.

Build quality and design

The bodies are plastic, and the collars have a positive, uniform feel across the set. The internal grip and seal (the usual stainless “teeth” ring and an O-ring) held onto polyurethane and nylon tubing consistently in my tests. Molded details are clean, and the parts don’t feel brittle. I especially appreciate the molded mounting ears on most of the multi-branch fittings: they’re not just decorative. I measured the mounting holes at 3 mm in diameter with 15 mm center-to-center spacing on the tees, which makes it easy to fasten them to a panel or a bit of plywood with M3 hardware or small wood screws.

Color-coding is minimal (blue accents), and the fittings are compact. Elbows rotate on the tube once installed—handy for getting a clean run—while still staying sealed.

Installation and day-to-day use

Push-to-connect lives or dies on two things: clean cuts and full insertion. With crisp, square cuts from a proper tube cutter, I had zero trouble. The fittings give a faint “double-stage” feel when inserting; push past the first resistance until the tube bottoms out. To release, press the collar squarely while pulling the tube—no wrestling required. Repeated connect/disconnect cycles didn’t nick or score the tubing noticeably, and the fittings kept their grip.

For the shop manifold, I mounted a row of tees on a scrap of aluminum angle using the built-in ears, then used elbows to turn down to each tool drop. The Y splitters came in handy where I wanted to branch off without making a hard 90-degree turn; they reduce turbulence a bit versus a tee in tight spaces.

Performance

I pressure-tested a small loop at 120 psi using 1/4-inch OD polyurethane tubing and soapy water on every joint. No bubbles at install. After a week of on-and-off use including a few tugged lines and half a dozen reconnections, everything remained dry. This is well within the advertised 145 psi limit, but it’s a useful benchmark for a plastic-bodied fitting.

On a lightweight CNC dust-shoe lifter (pneumatic cylinder), the elbows helped conserve space, and the ability to rotate after install helped route the line clear of the gantry. I didn’t see any measurable pressure drop attributable to the fittings themselves in this small setup; restrictions will come more from the tubing ID and run length than from these connectors.

Temperature-wise, I kept them in a climate-controlled shop and in a garage that ranged from roughly 50–90°F. They behaved as expected. I wouldn’t use them near engine compartments, hot end enclosures, or anywhere you anticipate temperatures flirting with or exceeding the 60°C (140°F) rating.

Compatibility and sizing notes

• These are for 1/4-inch OD tubing. That’s the outside diameter of the tube, not the inside diameter. If your “1/4-inch” drip or beverage line refers to ID, it probably won’t fit.
• They worked perfectly with 1/4-inch OD polyurethane and nylon air line. Soft PE tubing also seated and sealed, though stiffer tubing provides a crisper “lock.”
• Don’t mix metric 6 mm and 1/4-inch OD tubing in the same fitting; they are close but not interchangeable.
• This kit is marketed for air. While push-to-connect fittings are commonly used with water at low pressure, I’d stick to the stated “air only” use unless you’re comfortable assuming the risk and testing thoroughly.

What I liked

• Balanced assortment: The even split between straights, elbows, tees, and Ys covered most routing scenarios without fudging parts.
• Reliable seals: No leaks up to 120 psi in my tests with proper tube prep.
• Mounting ears that matter: The 3 mm holes and compact footprint made it easy to build tidy, semi-permanent manifolds without extra brackets.
• Easy service: The collars release cleanly, so changes don’t chew up your tubing.

Where it falls short

• Air-only rating: If you’re building water or mist systems, you’ll need to check manufacturer guidance elsewhere. This kit keeps its promise in pneumatics, but it’s not a universal fluid solution.
• No thread adapters: The set is purely in-line. If your project involves regulators, filters, or any NPT ports, you’ll need additional fittings.
• Temperature ceiling: 60°C is typical for plastic push-to-connect but still limiting. Keep it away from heat sources.
• Sizing expectations: Many users conflate 1/4-inch OD with “1/4-inch line” of other types. If your tubing spec isn’t clearly OD at 1/4-inch, expect headaches.

Practical tips

• Use a proper tube cutter to get square cuts; angled cuts are the number one cause of slow leaks.
• Debris is the enemy. Keep tubing ends clean and free of burrs so you don’t nick the O-ring on insertion.
• Push to a positive stop; mark the tube with a sharpie to verify full insertion depth when consistency matters.
• If you need to anchor runs, take advantage of the mounting ears and plan hole spacing (3 mm diameter, 15 mm centers on the tees I measured).
• Keep a couple of extra elbows and Ys at the bench—those are the parts you’ll add as your layout evolves.

Value

For the price, getting 40 pieces that seal reliably and install quickly is an easy win for light-to-medium-duty air projects. The assortment saves time, and the mounting features elevate the kit beyond generic connectors tossed in a bag. As long as you understand the “air only” scope and the 1/4-inch OD requirement, the value proposition is strong.

Bottom line

The Tailonz 1/4-inch push-to-connect kit hits the sweet spot for small pneumatic builds and shop air routing: dependable seals, a thoughtful mix of connectors, and mounting details that keep installations tidy. It isn’t a catch-all for every fluid or temperature scenario, and it won’t replace threaded adapters. But for air lines in the 0–145 psi range with 1/4-inch OD tubing, it does exactly what I want it to do with minimal fuss.

Recommendation: I recommend this kit if you’re working with 1/4-inch OD polyurethane, nylon, or soft PE tubing in air service and want a solid assortment that installs cleanly and holds pressure. It’s not the right choice if you need threaded interfaces, hot environments, or certified water/food-safe fittings—but within its wheelhouse, it’s a dependable, cost-effective staple to keep on the bench.
