Home TZH 3/4"Black Pipe Fitting, Home TZH 30 Pack Floor Flange/Elbow/Tee Combo for Industrial vintage style, Flanges/Elbow/Tee with Threaded Hole for DIY Project/Furniture/Shelving

Why I reached for this kit

I’ve been on a streak of industrial-style builds lately—floating shelves for a home office, a freestanding garment rack for a guest room, and a towel bar set in a bathroom refresh. Rather than cherry-pick individual fittings from a big-box store at a premium, I tried the Home TZH 3/4-inch pipe fitting kit. It’s a 30-piece mix of flanges, elbows, and tees designed for furniture and shelving builds, all threaded, all black iron. After several projects and a few stress tests, here’s how it faired.

What’s in the box

The assortment includes the three essentials for pipe furniture: floor flanges for mounting to wood or walls, 90-degree elbows, and tees for branching or frame corners. It’s all 3/4-inch NPT threading, which mates with standard 3/4-inch black steel pipe nipples you’ll find at any hardware store. There are no screws or pipe included, so plan your layout and buy pipe lengths accordingly.

Pieces arrived with a light protective oil, which is normal for black iron. I wiped everything down with a degreaser (mineral spirits works well) before assembly, then sealed after install to fend off rust and fingerprints.

Build quality and finish

The fittings are heavy cast iron with a textured, slightly crinkle-like black finish that suits the industrial look. The finish isn’t a delicate powder coat; it’s more utilitarian and forgiving. Expect minor casting seams and the occasional shallow divot—nothing out of the ordinary for this category.

Threading quality was better than I expected at this price. Most pieces threaded smoothly by hand and snugged up with a wrench without binding. On my set, one flange had slightly rough internal threads that needed a confident start and a touch of lubricant. I didn’t encounter any cross-threading, and I didn’t find paint overspray blocking threads.

A note on squareness: a few 90-degree elbows were a hair past true—call it roughly 92–93 degrees. For decorative builds it’s not a deal-breaker, but if you’re building a perfectly square frame, minor deviations can stack up. I’ll share workarounds below.

Assembly experience

Threaded builds are quick once you have your layout. With NPT threads, orientation is set by how far you tighten the joint. That’s convenient, but it means “clocking” components takes feel and a bit of planning.

What worked well:
- For shelves and towel bars, I threaded everything loosely, aligned the parts, then locked orientation with an extra quarter-turn using a pipe wrench. Teflon tape or a dab of thread compound adds friction if you need a joint to stop earlier.
- The flanges mounted cleanly to wood studs and solid wood. The four-hole pattern accepts common wood screws or small lags; I used 1/4-inch lags into studs and #10 pan-head screws with anchors in masonry.
- The tees held long crossbars rigid with no wobble once tightened.

Where precision mattered:
- On a freestanding garment rack, chasing perfect plumb and square took patience. The slightly acute elbows amplified when mirrored across a frame. I introduced a coupling and a short nipple on one corner to fine-tune the geometry without over-torquing the elbow.
- When mounting flanges to a wall, the slotted hole play helped level shelves even if the elbows weren’t mathematically perfect.

Strength and stability

For furniture and decor, the kit is stout. A pair of flanges and elbows supporting a 36-inch shelf on 3/4-inch pipe handled a 50-pound load (evenly distributed) without complaint. A single 48-inch garment bar between two tees comfortably held a week’s worth of clothing. These are not plumbing-rated parts in this context, and I wouldn’t use them for pressurized systems, but for static furniture loads they’re reassuringly solid. As always, your mounting method governs the real-world capacity: hit studs, use proper anchors, and don’t cheap out on screws.

Aesthetics

If you’re after a clean, modern-industrial look, the black iron texture and chunky silhouettes are on theme. On lighter woods like maple or ash, the contrast is great; on darker walnut, the fittings blend in more subtly. The finish will pick up faint rub marks out of the box; I prefer a matte clear coat (rattle-can polyurethane) after assembly to lock in the color and ease cleaning. For bathrooms, a clear coat is especially helpful to deter surface rust from humidity.

Compatibility and planning

• Size: These are 3/4-inch NPT fittings. The nominal 3/4-inch black pipe has an outside diameter of about 1.05 inches, so plan hole sizes and spacing accordingly.
• Screws and anchors: The kit doesn’t include fasteners. For studs, I like 1/4 x 1-1/2 inch lag screws. For masonry, sleeve anchors or quality wall anchors that match the flange hole size.
• Pipes: Buy pre-cut nipples for short segments and have longer runs cut and threaded at a hardware store if you don’t own a threader. Getting your pipe lengths trimmed to exact size keeps frames tight and reduces the need to over-rotate fittings for alignment.

Tips for better results

• Degrease before finishing: Wipe with mineral spirits, then dry thoroughly to avoid fingerprints telegraphing through your finish.
• Seal in damp areas: A clear matte polyurethane or wax finish helps prevent surface rust.
• Clocking control: Use Teflon tape or pipe dope to add friction so you can stop a joint exactly where you want it without over-tightening.
• Correct for elbow variance: Introduce a coupling and a short nipple to gain a few degrees of rotational freedom if square is critical.
• Pilot holes and hardware: Pre-drill mounting holes and use washers under screw heads to avoid marring the flange finish.
• Weight planning: For shelves, support every 16 to 24 inches and keep heavy loads close to mounting points.

Quirks and quality control

The set is consistent overall, but a couple of realities are worth noting:
- Elbows can be just shy of true 90 degrees. It’s common in cast fittings, and manageable with thread friction and clever layout.
- Expect occasional rough threads. I had one flange that needed a little persuasion to start cleanly. If a fitting feels wrong, back off and re-align—forcing it risks cross-threading.
- The finish is decorative. It can scuff during assembly; touch-ups with black enamel are easy.

None of these were project-stoppers, and they’re typical for budget-friendly cast iron fittings used in decor builds.

Value

Buying individual fittings piecemeal adds up fast. The convenience of a 30-piece assortment at a fair price is the main draw here. For me, it covered:
- A two-shelf wall unit with side supports
- A 48-inch garment rack
- Two towel bars with a spare tee and elbow left over

If you’re outfitting a single small project, you’ll likely have extras. I don’t mind—having spares on hand tends to inspire the next build.

The bottom line

The Home TZH kit hits the sweet spot for DIY furniture and shelving: solid cast iron, decent threading, and a finish that looks the part without requiring fussy handling. It’s not precision machine stock, and you may bump into an elbow that’s a touch off-square or a flange thread that wants a firmer start. But the value is strong, assembly is straightforward, and the results are sturdy and visually convincing.

Recommendation: I recommend this kit to anyone building industrial-style shelves, racks, or small furniture who wants a cost-effective, ready-on-the-bench assortment of 3/4-inch fittings. You’ll get dependable strength, an authentic look, and enough flexibility to complete multiple projects, provided you’re comfortable with a bit of thread-clock tinkering and basic finishing. If your work demands perfect geometry out of the box or you’re outfitting structural or pressurized systems, look to higher-tolerance or purpose-rated hardware. For the DIY furniture lane, this kit is an easy yes.
