What To Consider When Buying Stainless Steel Pipe Fittings

Stainless steel pipe fittingsStainless steel pipe fittings are used to join pipe ends to form them into various configurations. The fittings can close or extend pipes, join two pipes or more, change its diameter and alter its direction.

If you’re planning to do some pipework, here’s what you need to consider when purchasing fittings:

The Pipe Fitting End

The pipe’s fitting end needs to have a larger inner diameter compared to the rest of the pipe to keep the flow of your connection consistent. Using the wrong size for your fitting could narrow your pipe’s inner diameter. If you’re using the pipes to transport materials, inconsistent diameters could lead to blockages and overflows.

Types of Connections

There are different types of connectors to consider when selecting your pipe fittings. Fittings are classified as either threaded or slip and male or female.

Threaded pipes connect by screwing them together while slip fits use sleeves to slide into each other. Plastic pipes are usually slip fit or threaded while metal pipes are often threaded.

Male threaded fittings have exterior threads intended to screw on the inside of a pipe with a larger inner diameter and internal threads. Female threads have the internal threading to join the males.


Size is an important thing to consider when buying pipe fittings. Standard English sizes vary from 36’’ down to 1/8’’. Common metric dimensions range from <10mm to >1000mm. With male threaded fittings, size is measured from the outside edge. Female threaded fittings are measure the inside edge.

Pipe fittings come in various thickness and designs depending on what you’re using the pipes for. All pipes require distinctive fittings so ensure you get the right one. You can conveniently purchase pipe fittings from a reputable supplier.
