Pipe Fittings & Piping Systems Connections - Complete Guide
WHAT PIPE FITTINGS ARE LISTED?
We carry all pipe fittings that are essential to changing direction of flow, adapting or reducing sizes in piping systems.
Changing flow direction: elbows, tees or crosses.
Change the size of the pipe : use of reducers required (reducing tees, reducers).
To connect different components: couplings
To stop flow: caps
A pipe nipple is a short stub of pipe which has a male pipe thread at one or both ends. It used for connecting two other fittings. Nipples are used for connecting pipe, hoses, and valves. Pipe nipples are used in low-pressure piping.
There are different kinds of pipe fittings used in piping systems. The main and most commonly sought are: elbows, tees, reducers, unions, couplings, crosses, caps, swage nipples, plugs, bushings, adapters, outlets, valves & flanges.
These pipe fittings can be found in various pressure classes ranging from 150 PSI to 3000 LB. We also carry 2000# up to 6000# forged carbon steel fittings. We also carry MSS SP-114 fittings.

POPULAR PIPE FITTINGS - (threaded featured below)
Pipe bushings are used to join pipes of different sizes - usually by reducing a larger pipe fitting down to a smaller pipe. Bushings are usually threaded inside and outside. They take up very little space compared to a coupling or union, which serve to achieve the same goal of reducing down sizes. Has a hexagonal head for increased leverage and use with a wrench.
Threaded or socket weld pipe elbows are commonly used if you need to change the direction of flow. Most popular: 90 & 45 degree angles elbows. Elbows are a critical fitting used in plumbing. Street elbows feature male and female threaded ends to easily connect differing pipes or fittings. Side outlet elbows featuring a bend serve similar to a tee. 22-1/2 degree elbows are also available.
Caps are availabe in stainless steel 304 or 316 cast pipe fitting with female National Pipe Taper (NPT) threads. For closing the end of a male pipe. The cap fits over the end of a male pipe to stop flow. They are availble also with hex and square heads for increased leverage and use with a wrench during installation and disassembly.
Cross pipe fittings are 4-way fittings that are essentially just the combination of two tees. Many will opt to use two tees instead.
Flanges are used to connect pipes. The pipe is threaded or welded to the flanges which are then sealed together with bolts. Flanged connections are used extensively in industrial applications handling high pressures.
Reducing Couplings/Bell Reducers
Pipe couplings are used to lengthen the run of a pipe or change pipe sizes.
When reducing this becomes known as a bell reducer. Available with female threads or socket weld.
A pipe nipple is a short stub of pipe which has a male pipe thread at one or both ends. It used for connecting two other fittings. Nipples are used for connecting pipe, hoses, and valves. Pipe nipples are used in low-pressure pipe systems.
Pipe Tees are T-shaped with two outlets - at 90° to the connection to the main line. It is a short piece of pipe with a lateral outlet. Pipe tees are used to connect pipelines with a pipe at a right angle with the line. Tees are sized according to their run*. When the run of a tee is smaller than the side outlet*, it becomes a "bull head" fitting.
Run* - the horizontal or straight-through dimension of the fitting and the side outlet
Side outlet* - the "top" of the fitting, 90 degrees off the run
Unions are an alternative to couplings. Unions rely upon their own nut to create a seal between the pipe ends. This makes them the perfect choice for connecting two fixed pipes that are unable to be threaded into a regular coupling. Unions also make future repairs that much easier.
Valves are designed to control flow pressures and rates.
