Brass 4-Way Cross Pipe Fitting — Split One Line Into Four With Zero Hassle

When your plumbing, compressed air, or gas distribution project demands a clean four-way split from a single line, a poorly matched fitting can mean leaks, rework, and wasted time. DIYers, contractors, and workshop owners who need a reliable cross connector for water, air, or gas lines will find this brass 4-way cross pipe fitting built for exactly that job.

Each piece is machined from solid brass and features a true cross (4-port) body. Available in two pipe sizes — 1/2" (≈12.7 mm) and 3/4" (≈19.1 mm) — and in two thread configurations: all-male (M-M-M-M) or all-female (F-F-F-F) NPT threads. The 1/2" all-male variant weighs approximately 80 g per piece; the 3/4" all-female variant weighs approximately 170 g per piece. Order in quantities of 1, 2, 3, 5, 8, or 10 pieces to match your project scope.

Typical use cases include residential water distribution manifolds, compressed air branch lines in garages and workshops, and low-pressure gas supply networks. The cross body design makes it a go-to solution for four-way pipe junction installations and DIY plumbing cross connector projects where space and alignment matter.

🔗 Compatibility: Designed for NPT (National Pipe Taper) threaded systems standard in the US. Suitable for water, compressed air, and low-pressure gas lines. Not directly compatible with BSP threads — use an NPT-to-BSP adapter if needed.

✅ Key Features of These Brass 4-Way Cross Pipe Fittings

  • 🔩True Cross Body Design — Four ports arranged at 90° intervals allow a single supply line to branch in all four directions, ideal for four-way pipe junction installations in tight spaces.
  • 🛡️Solid Brass Construction — Machined from brass for natural corrosion resistance, making these fittings suitable for humid environments, outdoor installations, and long-term water line use.
  • 🔄Male & Female Thread Options — Choose M-M-M-M (all external threads) or F-F-F-F (all internal threads) to match your existing pipe configuration without extra adapters.
  • 📐Two Pipe Sizes Available — 1/2" NPT for standard residential water and air lines, and 3/4" NPT for higher-flow applications — both common sizes for DIY plumbing cross connector work.
  • 💨Multi-Media Rated — Engineered to handle water, compressed air, and gas distribution lines, giving you one fitting type that works across multiple systems in your home or workshop.
  • 📦Flexible Quantity Options — Available in packs of 1 to 10 pieces so you can stock exactly what you need for a single repair or a larger brass pipe fitting installation project.

❓ Frequently Asked Questions

How do I choose the right size — 1/2" or 3/4"?

Measure the outer diameter of your existing pipe or check the markings on your current fittings. A 1/2" NPT fitting typically suits pipes with an outer diameter of around 0.840" (21.3 mm), while a 3/4" NPT fitting suits pipes around 1.050" (26.7 mm). When in doubt, bring an existing fitting to a hardware store for comparison, or contact us to confirm before ordering.

What pressure can these brass cross fittings handle?

Brass NPT fittings of this type generally support working pressures up to 200 PSI for water and air at room temperature. Pressure ratings typically decrease at elevated temperatures. For high-pressure or high-temperature applications, contact us to confirm suitability before installation.

Can I use these fittings outdoors or in damp environments?

Yes. Brass is naturally corrosion-resistant and performs well in humid, outdoor, and wet environments. It is generally not recommended for direct saltwater immersion or highly acidic media without additional protective coatings. For most residential outdoor water and air line applications, brass is a reliable choice.

What thread standard do these fittings use — NPT or BSP?

These fittings use NPT (National Pipe Taper) threads, the standard for most US residential and commercial plumbing, compressed air, and gas systems. NPT threads are not directly interchangeable with BSP (British Standard Pipe) threads. If your system uses BSP threads, you will need an NPT-to-BSP adapter.

What is the difference between M-M-M-M and F-F-F-F configurations?

M-M-M-M means all four ports have male (external) threads — they screw into female-threaded sockets, valves, or couplings. F-F-F-F means all four ports have female (internal) threads — they accept male-threaded pipes, nipples, or studs. Choose the configuration that matches the threaded components already in your system.

Do I need Teflon tape or thread sealant with these fittings?

Yes, for water and gas lines it is strongly recommended to apply PTFE (Teflon) tape or a thread sealant compound to the male threads before assembly. This ensures a leak-free seal on tapered NPT connections. Wrap the tape clockwise (when facing the thread end) for 2–3 layers before threading the fitting in.

Are these fittings approved for natural gas or propane lines?

Brass fittings are generally used in natural gas and propane applications in residential settings. However, local building codes vary — always verify compliance with your local regulations and consult a licensed plumber or gas fitter before installing any fitting on a gas line.
