Black and galvanized pipe fittings are used for the conveyance of water, gas, air, and other fluids in residential and commercial piping systems. The two types of pipe fittings differ in how they are coated to protect them from corrosion. Black pipe fittings are coated with paint or enamel that can chip or flake over time, while galvanized pipe fittings have a coating of zinc that helps to prevent rust.

There are many different pipe fittings that can be used with galvanized pipes. Some of the most common fittings include elbows, tees, and caps. The galvanized pipe can also be used with threaded pipe fittings.

It is important to choose the right type of fitting for your needs, as each type of fitting has its own advantages and disadvantages. We partner with Midland Metal for all our black steel and galvanized pipe fittings, nipples, couplings, plugs, and flanges.

API couplings are a type of plumbing fitting that is used to connect pipes together. They are available in a variety of sizes and shapes and are used to join two pipes in order to create a watertight seal. API couplings are commonly used in plumbing applications and are available in a variety of materials including brass, bronze, copper, and plastic.

The American Petroleum Institute (API) has standards that work for oil and natural gas pipes. Our API couplings pass the API 5L & 5B standards. We phosphate all twelve of our black steel API couplings. The sizes are also taper tapped at ¾ per foot on the diameter.
