How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Low-Carbon Steel Round Tubes

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength.

Low-Carbon Steel Rectangular Tubes

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength.

Ultra-Strength Carbon Steel (AHSS) Round Tubes

The same steel used in automobile bodies, this AHSS (advanced high-strength steel) allows you to fabricate high-strength parts using thinner material than you could with other types of steel. It is formable, weldable, and more economical than alloy steel.

Easy-to-Weld 4130 Alloy Steel Round Tubes

4130 alloy steel has a low carbon content that provides good weldability. It's often used for gears, fasteners, and structural applications.

Easy-to-Weld 4130 Alloy Steel Rectangular Tubes

4130 alloy steel has a low carbon content that provides good weldability. It's often used for structural applications.

Multipurpose 4140 Alloy Steel Tubes

Also known as chrome-moly steel, this versatile 4140 alloy steel is used for a wide range of parts, such as axles, shafts, collets, and die holders. It resists fracturing from repeated stress.

Hard Wear-Resistant 52100 Alloy Steel Tubes

Easier to machine than 52100 alloy steel rods, these extremely hard and wear-resistant tubes are often used to create bearings, bushings, and other cylindrical parts that are under constant stress. They’re also known as chrome steel.

Iron and Steel Pipe and Pipe Fittings

Standard-Wall Steel Threaded Pipe Nipples and Pipe

Also known as Schedule 40, this steel pipe is designed for low-pressure applications.

Standard-Wall Steel Threaded
Pipe Nipple and Pipe Assortments

Assortments contain threaded pipe in various lengths.

Standard-Wall Steel Pipe Nipples and Pipe
with Right-Hand and Left-Hand Threads

Pipe has clockwise (right-hand) threads on one end and counterclockwise (left-hand) threads on the other end. When you use a wrench to turn, connections on both ends tighten at the same time.

Standard-Wall Galvanized Steel
Threaded Pipe Nipples and Pipe

Made of galvanized steel, this Schedule 40 pipe has fair corrosion resistance and is designed for low-pressure applications.

Standard-Wall Galvanized Steel Pipe Nipples
and Pipe for Joining Dissimilar Metals

A plastic sleeve prevents destructive corrosion when connecting different metals.

Standard-Wall Galvanized Steel Threaded
Pipe Nipple and Pipe Assortments

Assortments contain threaded pipe in various lengths.

Thick-Wall Steel Threaded Pipe Nipples and Pipe

Typically used with medium-pressure iron and steel threaded pipe fittings. Also known as Schedule 80.

Thick-Wall Galvanized Iron and Steel
Threaded Pipe Nipples and Pipe

Typically used with medium-pressure galvanized iron and steel threaded pipe fittings. Also known as Schedule 80.

Extra-Thick-Wall Steel Threaded Pipe Nipples and Pipe

Typically used with high-pressure iron and steel threaded pipe fittings. Also known as Schedule 160.

Extra-Thick-Wall Galvanized Steel
Threaded Pipe Nipples and Pipe

Typically used with high-pressure galvanized iron and steel threaded pipe fittings. Also known as Schedule 160.

Super-Thick-Wall Steel Threaded Pipe Nipples and Pipe

Typically used with extreme-pressure iron and steel threaded pipe fittings. Also known as Schedule XXH.

Thick-Wall Steel Unthreaded Pipe

Typically used with thick-wall and high-pressure iron and steel unthreaded pipe fittings. Also known as Schedule 80.

Standard-Wall Steel Unthreaded Pipe Nipples and Pipe

Typically used with standard-wall and low-pressure iron and steel unthreaded pipe fittings. Also known as Schedule 40.

Extra-Thick-Wall Steel Unthreaded Pipe

Typically used with extreme-pressure iron and steel unthreaded pipe fittings. Pipe is also known as Schedule XXH .

Standard-Wall Grooved-End
Steel Pipe Nipples and Pipe

This steel pipe has grooved ends that connect to fittings with a clamp (sold separately) for an easy way to install piping systems.

Lamp Pipe

Connect lamp components and conceal wires.

Hollow Female Threaded Rods

Connect and separate threaded rods, studs, and other components. These hollow rods have internal threads on both ends, so you can make connections and still pass wiring and other objects through the center of the rod.

Connecting Rods

Internally Threaded Connecting Rods

Designed for use with right-hand, externally threaded rod ends, these rods have right-hand threads on both ends. Use them for remote valve operators, throttle controllers, shifting mechanisms, and virtually any push/pull assembly.

Internally Threaded Turnbuckle-Style Connecting Rods

Similar to turnbuckles, these rods have right-hand threads on one end and left-hand threads on the other so you can make a linkage that adjusts for tension.
