A 12-inch steel nipple with male threads that lock into black pipe fittings.

When you need to connect steel pipe sections, this 12-inch nipple with a 2-inch nominal diameter and male threaded ends is the bridging piece. It is Schedule 40 alloy steel, so it carries the same wall strength as standard black pipe, and the black coating gives it a clean, uniform look in exposed runs. Owners found it hard to locate 2″ black pipe at big-box stores, which makes this a convenient find.

The threads are consistently praised for seating properly, ensuring a tight, leak-free joint. One buyer used it to fix a rusted basement drain pipe and reported the threads were “a perfect match” and everything went well. It is also strong enough for shop use, with an owner running air mixed with propane for a forge through it.

The honest fit note: a few buyers have received the wrong size, so verify the 2-inch nominal diameter against your existing fitting before you start. Also, the steel is on the brittle side if you plan to weld it, so treat it as a bolt-on connector rather than a weld blank.

Four pre-cut 17-inch white pipes that turn a DIY idea into a weekend build.

This four-pack gives you 17-inch white Sch40 PVC sections right from the start, which removes the classic headache of hauling a 10-foot pipe home and cutting it yourself. One owner summed it up perfectly: it “saved me a trip to the hardware store on a busy weekend.” These are exactly as described, with a 2-inch outside diameter that fits standard schedule 40 fittings.

The four pieces offer flexibility for multiple projects. Use them for a greenhouse frame, a paint tent, garden supports, or even a Halloween project — one builder cut 45-degree angles into the ends to make frame corners for a DIY craft. The PVC is durable and reusable, holding up to sun and water exposure, and the 4.3-pound total weight keeps them easy to carry around the yard.

Buyers use these for everything from catfish jugs to electrical conduit, which tells you the size and wall are genuinely true to spec. A few DIYers advise bringing a pipe with you when buying elbows, since fitting sizes can vary slightly between brands.

Galvanized 10-inch nipple that comes ready to use, no rust cleaning required.

The galvanized finish provides a corrosion-resistant surface on this 10-inch nipple with 2″ NPT male threads, arriving clean and ready to install. That is a real convenience — one owner building a stand-up desk noted there was “no cleaning or rust removal required,” which is often not the case with store-bought galvanized fittings. It is Schedule 40 standard steel pipe, so the wall is solid for structural work.

This piece shines in furniture and structural framing. The owner building a galvanized pipe desk frame found a “drastic difference” between these and the fittings at big-box stores, which is a strong signal on machining quality and finish consistency. It has also been used as an exhaust pipe section for an old engine, which shows the threaded connection holds up under vibration.

At 10 inches, it is shorter than the Supply Giant steel nipple, but the galvanized coating is the trade-off that wins for exposed or damp locations. If your project will be seen or might get wet, the rust protection is worth the premium positioning.

A 60-inch USA-made white pipe for pool, spa, and cold-water supply lines.

It is made in the USA and rated for potable water applications, which means you can trust it for a drinking-water supply line or repair. The 2-inch outside diameter matches standard pressure fittings.

Owners have put it to work fixing a pool solar heating system leak and upgrading a washer drain, with one molding it into an offset using a heat gun. The material is non-toxic and lightweight, and the socket ends take primer and solvent cement just like any standard PVC joint. The thicker wall adds durability, though it also increases weight.

Buyers report the functionality is what stands out, with accurate measurements matching the listing. Since it is a single 60-inch piece rather than a multi-pack, it is the right call when you need a longer continuous run for a specific repair.

A 30-inch black steel bar that doubles as serious torque for stubborn fittings.

This 30-inch long, 2-inch diameter black coated Schedule 40 steel pipe is a brute. It weighs 5.3 pounds and is built to handle leverage work — owners have used it as a breaker bar to unscrew Big Blue water filter containers and to gain leverage when installing wire-rope crimps. If you have a stuck fitting, this will give you the mechanical advantage to break it free.

Beyond the workshop, it has found creative uses like a yard display stand for a horse head and as a wedge stick. The black coating keeps it looking clean, and the Schedule 40 wall means it won’t flex or bend under load. A buyer who needed just 5 feet of 2″ steel pipe appreciated not having to order a 21-foot minimum from a supply house.

This is not really a plumbing connector — there are no threads to speak of. It is a raw, pre-cut steel tube for strength applications. If your goal is to join pipes with fittings, the 12-inch threaded nipple above is the better fit.

Six-piece Sch40 pack rated at 600 PSI for demanding water lines.

This is the pack that brings serious pressure ratings to your DIY build. Each of the six 2-inch pipes is rated at 600 PSI at 73°F and manufactured to ASTM D1785 specifications, which is the standard for dimensional accuracy in PVC pipe. That pressure rating means this will handle a demanding water line, not just a gravity-fed drain.

Owners are using it in the garden for hose-bib supply and trellis structures, with the pipe staying nice and straight. The white, rigid PVC resists corrosion and the 17-inch segments are easy to connect and customize. Since it comes as a six-pack, you have plenty of material for a greenhouse frame, a garden gate, or a fencing project without extra trips.

One note: the listing mentions multiple size options, so confirm your pack is the 2-inch size when ordering. The pressure rating and six-piece count make this a strong value for anyone building a water-fed structure.

A 25-foot black flex hose that bends around obstacles for underground drainage.

This 25-foot coil of black flexible PVC is the answer when a straight rigid pipe won’t work. With a 2.38-inch outside diameter and an inside diameter meant for Schedule 40 fittings, it connects to standard PVC fittings and glue just like rigid pipe. It’s manufactured in the USA from virgin PVC compound and is phthalate-free, which is a nice safety note for water features.

Owners use it for sump pump discharge lines and pond plumbing, with the 60 PSI maximum pressure handling typical drainage flow. The flexible wall makes it easier to lay in a dug ditch and route around corners without extra elbows. It resists crushing from rocks underground, and the temperature range of -10 to 150°F covers most climates.

The honest trade-off is the flexibility itself — some owners find it too rigid to bend easily, and the coiled memory makes it hard to straighten. The tip is to leave it in the sun before unrolling to soften it. Buyers consistently rate the quality and durability highly, noting it is heavy-duty and lasts a long time underground.
