The SUPPLY GIANT CNVO0200 straight union is a pressure-rated workhorse built for 150 lb. applications. Its female threaded connects on both ends allow you to join two sections of 2″ pipe securely, and the factory pressure testing ensures you won’t discover a leak after installation. The black malleable iron construction delivers the tensile strength needed for both gas and air systems without adding unnecessary bulk.

Users consistently report no leaks and a perfect fit with standard 2″ NPT pipes. The UL and FM approvals add an extra layer of trust for installations that require code compliance. The compact 3.4-inch dimensions make it easy to work into tight spaces where longer fittings simply won’t fit.

If you need a reliable union for a permanent line — particularly where safety certification matters — this component handles the job with zero fuss. The threading is clean and consistent, matching seamlessly with both domestic and imported pipes.

Anvil’s malleable iron tee is a straightforward, US-made fitting designed to branch three pipes at a 90-degree angle. Each of the three ends features female NPT threads that create a reliable seal when paired with male threaded nipples. The black finish resists corrosion in gas and oil environments, making it a solid choice for splitting a supply line.

Customer feedback highlights the clean thread cutting and tight fit that eliminates leaks without requiring excessive torque. The 2.6-pound weight reflects the dense malleable iron construction that holds up under substantial mechanical stress. Many buyers note that it outperforms cheaper Chinese alternatives found at big-box stores, especially at this price point.

For anyone branching a gas line, air system, or even a structural furniture frame, this tee delivers precision threads and genuine US manufacturing. The Anvil brand has been a standard in commercial plumbing for decades, and this fitting carries that reputation with consistent quality.

PIPE DECOR’s 4-pack of floor flanges brings authentic 2″ malleable iron construction with a steel grey finish that matches the industrial aesthetic of any DIY furniture project. Each flange features four screw holes for secure mounting to floors, walls, or wooden shelves. The threading is consistent with standard 2″ NPT black pipe, so you can mix and match with other fittings without compatibility issues.

Buyers appreciate the commercial-grade quality that rivals what you would find at a local hardware store, often noting the clean threads and absence of burrs. The flanges arrive lightly oiled to prevent rust during storage, which means a quick wipe-down or coating of primer before painting is recommended. The multipack format saves you from buying singles at inflated prices.

For shelving brackets, table legs, or pipe clothing racks, this flange set provides the visual weight and stability you need. The dark grey finish offers a slightly more refined look than pure black, working well in both rustic and contemporary interiors.

This 2-pack of PIPE DECOR black steel pipes gives you two pre-cut 24-inch sections of Schedule 40 pipe with male threads on both ends. The steel construction offers better rust resistance than standard iron, making it suitable for both gas lines and furniture builds that may encounter moisture. The threads are factory-cut and meet ASME and ASTM standards for dimensional accuracy.

Users consistently note the substantial wall thickness and the absence of stickers or labels that would require harsh solvents to remove. The pipes do arrive coated in light industrial grease, so plan for cleaning with degreaser and a rag before assembly or painting. For shelving systems, table frames, or workbench supports, these lengths eliminate the hassle of cutting and threading raw pipe.

The 24-inch length is versatile for standard furniture heights and shelf spans. The included cleaning and sealing guide walks you through surface prep, ensuring your final project has a uniform, professional appearance. If you need longer sections, these can be joined with additional nipples or unions.

Home TZH’s 4-pack of floor flanges offers an accessible entry point for DIY furniture builders without sacrificing thread quality. Each flange is 100% factory tested to ensure the close-bite threading won’t loosen over time. The black iron construction delivers the classic industrial look, and the four standard screw holes make mounting to walls, floors, or shelves straightforward.

Buyers report smooth finishes and well-cut threads that mate cleanly with standard 2″ NPT pipes. Several customers mention using these flanges for wall-mounted clothes racks, shelving brackets, and even wooden pole guides. The 1.8-kilogram total weight speaks to the solid iron material that provides stable support for furniture projects.

Given the affordable price for a 4-pack, these flanges are a budget-friendly option for large builds that require many mounting points. Keep in mind that the raw iron may need a coat of paint to prevent surface rust over time, especially in humid environments.

This Anvil steel nipple is a 12-inch section of 2″ pipe with male NPT threads on both ends, built to join female-threaded fittings or to extend an existing pipe run. The steel material meets ASTM A53 and ASME B 1.20.1 specifications, ensuring dimensional consistency and strength for gas, oil, or air applications. The black finish provides basic corrosion resistance in dry environments.

Customers using it for gas lines note that the threads are well-formed and create a strong seal when paired with the appropriate thread tape or compound. One creative user even repurposed it as a reinforcement post for an office chair, proving the structural strength of the steel. The 1.6-ounce weight reflects the lighter steel material compared to malleable iron alternatives.

For anyone needing a precise 12-inch extension between two fittings, this nipple delivers the correct length without the waste of cutting down a longer pipe. The steel composition also means less weight in vertical furniture builds where every ounce counts.

The Sealproof flexible PVC pipe is a 50-foot roll of 2-inch internal diameter Schedule 40 hose designed for low-pressure drainage, sump pump lines, and aquaculture applications. Unlike rigid black iron pipe, this flexible tubing uses a rigid PVC spiral to resist crushing while maintaining the ability to bend around obstacles. The maximum pressure rating of 60 PSI makes it suitable for gravity-fed or low-pressure systems.

Users highlight its durability underground and resistance to rocks and soil pressure when buried. The smooth interior surface minimizes friction loss, and the phthalate-free virgin PVC compound is safe for pond and aquaculture use. The tubing is stiffer than smaller diameters, so laying it in the sun before installation improves flexibility for tighter bends.

This is not a substitute for rigid black pipe in gas or high-pressure applications, but for drainage, irrigation, and flexible connections, it outperforms rigid alternatives by eliminating the need for multiple fittings and elbows. The made-in-USA quality ensures consistent wall thickness and dimensional accuracy.
