Pushglossy 50 Pcs 3/8" - 1/2" Pex 90 Degree Bend Support, Plastic 90 Degree Elbow Tubing Bend Support Black Pex Fittings Clamps Pipe Holder 1/2 Inch

Why I reached for these bend supports

On a recent whole-house repipe, I wanted clean 90° turns on 1/2-inch home runs without stacking a bunch of brass elbows or fighting the memory of the tube. I tried the Pushglossy bend supports to see if they could keep bends consistent, cut down on fittings, and speed up rough-in. They quickly became a standard step in my layout: mark the turn, fasten the support, snap the tube, and move on.

Design and build

Each support is a rigid plastic 90° guide with a flat mounting plate and pre-drilled holes. The arc is long enough to keep 3/8–1/2 inch PEX from kinking, yet compact enough to fit on a stud face or cabinet wall. The black engineering plastic feels dense and uniform with smooth edges where the tube clips in. There’s enough stiffness to maintain a true right angle without the support flexing under line pressure or when you tug the run to make a connection.

The channel is sized to accept both 3/8-inch and 1/2-inch PEX. With 1/2-inch tube, the snap fit is positive—press until you hear/feel the click, and it stays put. With 3/8-inch, there’s naturally a little less contact area, but the guide still keeps the turn aligned and off the wood. The finish hides scuffs and looks tidy on exposed runs in mechanical rooms.

There are no fasteners in the box, which is fine; you can choose what works for your substrate. The pre-drilled holes accept common nails or screws. I used nails on open framing for speed and switched to pan-head screws inside cabinets and tight corners.

Installation experience

The practical advantage of these supports is how quickly they establish a repeatable, code-friendly bend without wrestling the tubing. My workflow went like this:

• Lay out the path and mark the center of the turn on the framing.
• Fasten the support so the arc lines up with the incoming and outgoing runs.
• Snap the PEX into the channel and continue pulling the line.

Because the support holds the tube away from edges, it also reduces abrasion where a DIY bend might rub the corner of a stud or shelf. The snap fit is strong enough that I could route the line, step back, and it stayed put while I made connections. If I wanted to re-route, popping the tube back out took a thumb and a little twist—no tools, no damage to the tube or the support.

They make a visible difference in clean turnouts at manifolds, water heater closets, mixing valves, and under-sink runs where exposed pipework benefits from tidy geometry. In a basement ceiling, I used them to drop 1/2-inch lines down walls; the turns were uniform from bay to bay, which also made strapping the verticals easier.

Performance and day-to-day use

Functionally, these supports do exactly what they promise:

• Maintain a true 90° without a brass/plastic elbow, avoiding added flow restriction at the fitting.
• Prevent kinks and flattening on tighter turns.
• Keep tubing from vibrating against wood when fixtures open and close quickly.
• Look better than a freehand bend, especially where the run is visible.

I used them with both PEX-A (expansion) and PEX-B (crimp) tubing. The outer diameters are standardized in these sizes, so compatibility wasn’t an issue. With PEX-A’s extra flexibility, the bend set cleanly and seated with a crisp snap. With PEX-B’s stiffer feel—especially on a cool morning—I warmed the tube slightly by working it with my hands before snapping it in. Either way, the support prevented ovaling on the inside of the turn.

One nice side effect: because the radius stays consistent, the tubing aligns more naturally with manifolds and valves, which makes the last inch of connection less fussy. I also noticed fewer squeaks on quick valve closures where unsupported bends might chatter against framing.

Durability and tolerances

The plastic has held up well around typical domestic hot and cold lines. I used several a foot or two from a water heater and on a recirculation return without any softening or creep after weeks in service. I wouldn’t place any plastic support right up against a heat source, but in everyday plumbing locations these felt stable.

In terms of toughness, the parts survived normal abuse in my hands—fastening, pushing lines in and out, and bumping them during pull-throughs—without cracking. I did learn two small lessons:

• When snapping in 1/2-inch PEX on a cold day, don’t force a tight bend into the support at an odd angle. Bring the tube in line with the arc and press evenly. It avoids stressing a single point on the clip.
• With 3/8-inch, if you’re concerned about rattle on a long horizontal, add a nearby strap. The support handles the turn; the strap keeps the run quiet.

Overall, the plastic’s stiffness is a feature—you get a square, non-sagging corner—but it rewards a straight, controlled snap rather than a twist-and-shove.

Planning and layout considerations

A few practical notes from layout:

• Account for length. The arc takes roughly 6–7 inches along each leg. In tight cavities, pre-position the support before pulling tube so you don’t paint yourself into a corner.
• Choose fasteners to suit. Nails are fast on studs; screws give better control in finish spaces and into plywood. In concrete or tile backers, anchor accordingly.
• Don’t substitute for protection plates. These supports guide bends; they don’t replace metal nail plates where code requires them.
• Avoid direct sunlight. Like most plastics, long-term UV isn’t a friend. Store and install accordingly if your runs will be exposed.

Alternatives and value

Compared to brass elbows, these supports cost less per turn, eliminate two joints, and remove a potential flow pinch point. Versus flexible bend sleeves or metal radius guides, the Pushglossy supports are quicker to mount and look more intentional on finished surfaces. Metal supports can be more forgiving if you regularly push bends at the edge of what PEX will tolerate, but they’re also bulkier and pricier.

Buying in a pack makes sense for a house-wide repipe, a basement finishing project, or a manifold retrofit; you’ll use a surprising number on a tidy install. For a single vanity or laundry run, you’ll have extras, but they’re the sort of shop staple that gets used up over time.

What could be better

• No fasteners included. Not a deal-breaker, but having a small starter pack of appropriate nails or screws would make first use simpler.
• Only for 3/8–1/2 inch. If your system mixes in 3/4-inch lines, you’ll need a different size to keep that same consistent look and radius.
• In very tight cabinets, the fixed 90° geometry can be a hair long. A compact radius option would be handy for those situations.

None of these are functional flaws; they’re more about scope and convenience.

Tips for best results

• Warm the tubing slightly with your hands in cold conditions before snapping it in.
• Align the tube with the arc and press evenly; don’t lever the clip with the tubing.
• Use an extra nearby strap on long runs to keep everything quiet and aligned.
• Pre-mark your turns so the finished geometry lines up with manifolds and valves without strain.

Verdict

The Pushglossy bend supports do the simple things right: they hold a true 90°, prevent kinks, speed up installation, and produce a cleaner-looking job. The plastic feels robust, the snap fit is reliable, and the pre-drilled plate makes mounting straightforward on a variety of surfaces. For 3/8–1/2 inch PEX runs, they’re an easy way to reduce fittings, improve consistency, and minimize vibration at corners.

Recommendation: I recommend these for anyone running 3/8- or 1/2-inch PEX who wants repeatable, professional-looking bends without extra fittings. They save time, reduce potential flow restrictions, and tidy up rough-in work. If your project relies heavily on 3/4-inch lines or you’re constantly working in ultra-tight cabinetry, you’ll need additional sizes or different styles alongside these. Otherwise, keep a box on the shelf—you’ll use them.
