Pick cross fittings by looking at material, connection type, and what your system needs. Galvanized malleable iron and stainless steel are strong. They do not rust easily and work well for hard jobs.
Install fittings the right way and check them often to stop leaks and damage. Always use the right pipe size, thread type, and pressure rating. This keeps your system safe and working well.
What Is a Crossing Fitting?
Definition
When you work with pipes, you often need to connect them in different directions. A crossing fitting helps you do just that. You use cross fittings when you want to join four pipes at right angles. Each pipe connects to one of the four outlets, making it easy to split or combine flows. This type of fitting is also called a cross.
You see cross fittings in many places, like plumbing, HVAC, and industrial systems. They let you build strong, stable pipe networks that can handle high pressure and heavy use. If you need to branch out or bring together several pipe runs, a crossing fitting is the tool for the job.
Structure and Function
A cross fitting has a simple but powerful design. Picture a plus sign (+). Each arm of the cross has an opening for a pipe. All four outlets sit at 90-degree angles. This shape lets you connect pipes so they cross or branch out in different directions. The cross fitting makes it easy to control how water, gas, or steam moves through your system. You can send flow from one pipe into three others, or combine flows from several pipes into one. Cross fittings have thick walls and are made from strong materials like malleable iron.
This helps them handle high pressure and keeps your system safe. The threaded ends on each outlet make installation quick and secure. You get a tight seal that prevents leaks. Cross fittings are key parts of complex pipe systems, giving you the flexibility and strength you need.
There are many kinds of cross fittings. Each kind works best for certain jobs. You should choose the right cross for your pipes. Let’s look at cross fittings by material, connection, and design.
By Material (Malleable Iron, PVC, Stainless Steel)
Cross fittings are made from different materials. Each material is good for different uses. Some work better for water. Some are better for chemicals. Some are strong for heavy-duty jobs. Here are the most common materials for cross fittings:
MaterialAdvantagesDisadvantages / NotesPVCLight, does not rustNot good for hot waterCopperStrong, works for hot and cold waterCosts moreStainless SteelVery strong, does not rust, handles high pressureExpensiveBrassDoes not rust, lasts longHeavier than PVCAluminumLight, resists chemicalsNot as strong as steelTitaniumDoes not rust, can be recycledCosts a lot, used for special jobsCast Carbon SteelVery strong, flexible designCosts more than iron fittingsMalleable IronVery strong, tough, does not rustNeeds skilled workers to install
PVC 4 way pipe connectors are used in homes. They are light and easy to put in. Stainless steel 4 way pipe connectors are good for hot water or high pressure. Metal 4 way pipe connectors like malleable iron or brass are strong for hard jobs. ABS 4 way pipe connectors are also used for light jobs.
Let’s see the technical details for these materials:

PVC pressure ratings change with size and temperature:
For outdoor or high pressure jobs, galvanized malleable iron is a great choice. It is strong, does not rust, and lasts a long time. The zinc layer stops rust, so cross fittings last longer in wet places.
→ Tip: Always check the material before you buy cross fittings. The right material keeps your pipes safe and working well.
By Connection (Threaded, Welded, Flanged)
Cross fittings have different ways to connect. You should match the connection to your needs. Here is how the main connection types compare:

You can put them in fast and take them apart to fix things. Welded cross fittings are best for big jobs where you need strong, leak-free joints. Flanged cross fittings are good for large systems that need high pressure and easy fixing.
The 4 way pipe connector from JIANZHI uses threaded connections. This makes it easy to install and gives a tight seal. You can trust these cross fittings for high pressure jobs.
Types of 4 Way Pipe Connectors
There are many types of 4 way pipe connectors. Some are for plumbing, some for big jobs, and some for furniture or racks. The most common types of 4 way pipe connectors are:
Metal 4 way pipe connectors like galvanized malleable iron and stainless steel are strong and last long. These cross fittings handle high pressure and do not rust. You see them in water, heating, and chemical systems. PVC and ABS 4 way pipe connectors are good for lighter jobs like home plumbing or shelves.
Here are the good things about galvanized malleable iron cross fittings:
