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-Pressure Galvanized Iron
and Steel Threaded Pipe Fittings

The galvanized finish on these fittings provides fair corrosion resistance. Fittings are for use in low-pressure applications.

Low-Pressure Galvanized Iron and Steel
Threaded Pipe Fittings with Sealant

The male threads on these fittings have a sealant applied for extra leak protection.

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.

Compact Precision Extreme-Pressure
Steel Threaded Pipe Fittings

Made to tighter tolerances than other steel pipe fittings, these are also known as instrumentation fittings.

High-Pressure Galvanized
Steel Threaded Pipe Fittings

A galvanized finish gives these fittings better corrosion resistance than our plain steel high-pressure fittings. Also known as Pressure Class 3000 fittings.

Vacuum Fittings for Steel Tubing

Use these fittings in an air vacuum system to avoid the hassle of brazing and welding. Insert two fittings into a clamp and tighten to form a secure seal in steel tubing.

Slotted Unthreaded Spacers

An economical alternative to standard unthreaded spacers.

Duct and Fittings

Standard Duct and Fittings

No need for clamps or connectors—duct and fittings have a male end that is slightly smaller than its female end for simple assembly.

Crush-Resistant Spiral Duct and Fittings

A spiral seam gives this duct greater strength and rigidity than standard duct.

Quick-Disconnect Duct and Fittings

Join duct and fittings with quick-release clamps for faster disassembly and cleanout than other duct systems.

Sure-Seal Spiral Duct and Fittings

Fittings have gaskets which create a tight seal—you don't need to seal joints with coating or tape.

Rectangular Duct and Fittings

Often used in tight spaces, such as in walls and ceilings, rectangular duct allows you to select larger sizes without increasing duct height.

Duct Noise Reducers

These noise reducers mount directly to spiral duct to decrease noise by as much as 50%.
