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.

High-Pressure Brass Threaded
Pipe Fittings for Drinking Water

Use these heavy-duty brass fittings for high-pressure drinking water applications.

High-Pressure Brass Threaded Pipe
Nipples and Pipe for Drinking Water

Typically used with high-pressure brass and bronze threaded pipe fittings.

Low-Pressure Brass and Bronze Threaded Pipe Fittings

Use these fittings in low-pressure flow applications. They have good corrosion resistance.

Standard-Wall Brass Threaded Pipe Nipples and Pipe

Typically used with low-pressure brass and bronze threaded pipe fittings.

Low-Pressure Brass Threaded
Pipe Fittings with Sealant

The male threads on these brass fittings have a sealant applied for extra protection against leaks. Also known as Class 125 fittings, they are built for use in low-pressure applications.

Low-Pressure Plated Brass Threaded Pipe Fittings

Used in low-pressure pipe lines, these brass fittings have a plating that makes them shiny and improves corrosion resistance.

Extreme-Pressure Brass Threaded Pipe Fittings

Extreme pressures are no problem for these heavy-duty brass fittings.

Precision Extreme-Pressure
Brass Threaded Pipe Fittings

Also known as instrumentation fittings, these have the most precise threads and the tightest tolerances of all the brass pipe fittings we offer.

Precision Extreme-Pressure Brass
Threaded Pipe Nipples and Pipe

Typically used with precision extreme-pressure brass and bronze threaded pipe fittings.

Medium-Pressure Brass and
Bronze Threaded Pipe Fittings

Choose these fittings when you need better strength than our low-pressure brass and bronze pipe fittings.

Thick-Wall Brass Threaded Pipe Nipples and Pipe

Typically used with medium-pressure brass and bronze threaded pipe fittings.

Hose Fittings

Easy-Fit Barbed Hose Fittings for Air and Water

Low-profile barbs and a longer first barb allow for a smoother, easier installation than other barbed fittings. Slide the barbed end into hose and secure with a clamp.

Tight-Seal Barbed Hose Fittings for Air and Water

Also known as ball-seat hose nipples, these fittings consist of a barbed shaft with a rounded end that sits inside a female threaded nut. When mated with a male threaded fitting, the rounded end presses tightly against the inside of the male threads for a better seal than a single-piece fitting. Once assembled, insert the barbed end into hose and secure with a clamp or a crimp-on hose ferrule.

Metal Garden Hose Fittings for Drinking Water

Fittings meet NSF/ANSI Standard 61 for drinking water. Attach them to garden hose for a variety of water supply applications. They are metal for better durability than plastic garden hose fittings.

Drinking Water Hose Fittings

Fittings meet NSF/ANSI Standard 61 for drinking (potable) water.

Tubing and Tube Fittings

Brass Push-to-Connect Fittings for Copper Tubing

Choose these metal fittings when you need better durability than our plastic push-to-connect fittings.

Yor-Lok Fittings for Copper Tubing

Compression Tube Fittings for Drinking Water

These brass fittings meet NSF/ANSI 372 for drinking water. They include a nut with a built-in sleeve (ferrule), so there’s no need to remove the nut for assembly.

Barbed Tube Fittings for Drinking Water

Connect these fittings to tubing with a ring and a crimping tool (both sold separately). Safe to use with drinking water, these fittings meet the strict standards of NSF/ANSI 61.

Brass Push-to-Connect Fittings for Plastic
Tubing—Food, Beverage, and Dairy

Made of brass, these fittings withstand frequent washdowns in food-processing applications. They also adhere to NSF/ANSI safety standards, so they’re safe to use with food, beverages, and dairy.
