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 Brass and Bronze Threaded Pipe Fittings

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

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 Pressure 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.

High-Pressure Brass Threaded Pipe Fittings

These brass fittings have the strength to handle high-pressure applications.

High-Pressure Brass Threaded
Pipe Fittings with Sealant

Not only do these brass fittings have the strength to handle high-pressure applications, the male threads have a sealant applied for extra protection against leaks.

High-Pressure Brass Threaded
Pipe Fittings for Drinking Water

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

High-Pressure Plated Brass Threaded Pipe Fittings

The plating on these brass fittings creates a shiny finish and provides extra protection in corrosive environments. Fittings have the strength to handle high-pressure applications.

Miniature High-Pressure Brass Threaded Pipe Fittings

When space in your pipe line is limited, choose these miniature fittings that are one inch or less in length.

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.

Medium-Pressure Plated Brass Threaded Pipe Fittings

Plated with nickel, these brass fittings resist rust better than steel and unfinished brass fittings. Select them when you need more strength in corrosive environments to handle higher pressures than our low-pressure 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.

Manifolds

Right-Angle Flow Rectangular Manifolds

Distribute air or fluid to multiple locations from a single supply source with these manifolds. They are also known as headers.

Miniature Hex Manifolds

A great solution when space is at a premium, these manifolds are less than an inch in height, yet allow you to supply up to 12 lines from one distribution point.

Tube Fittings for Copper and Brass Tubing

Brass Push-to-Connect Fittings for Copper Tubing

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

45° Flared Fittings for Copper and Brass Tubing

No sleeve is required to assemble these fittings, which makes for a faster, more convenient installation compared to 37° flared fittings. They are also known as refrigeration and SAE fittings.

Yor-Lok Fittings for Copper Tubing

Precision Compression Fittings for Copper Tubing

Also known as instrumentation fittings, these are made to tighter tolerances than standard compression fittings. They are compatible with Parker CPI fittings.

Compression Fittings for Copper Tubing

Tube Fittings for Plastic and Rubber Tubing—Air and Water

Brass Low-Pressure Barbed
Tube Fittings for Air and Water

Fittings have good corrosion resistance.

Nickel-Plated Brass Low-Pressure
Barbed Tube Fittings for Air and Water

The nickel plating on these fittings provides better corrosion resistance than unplated brass fittings.

Brass Push-to-Connect Tube Fittings for Air

Made of brass, these fittings have good corrosion resistance.

Nickel-Plated Brass Push-to-Connect
Tube Fittings for Air

Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings.

Low-Temperature/High-Pressure D.O.T.
Push-to-Connect Tube Fittings for Air

Use at pressures up to 250 psi.

Tight-Seal Brass Compression
Tube Fittings for Air and Water

A built-in tube support slips inside the tubing to prevent collapsing and provides a sturdy connection for an extra-tight seal.

Brass Compression Tube Fittings for Air and Water

A single sleeve (ferrule) compresses the tubing as you tighten the nut on these fittings, creating a strong seal. They are brass for good corrosion resistance.

Hose Fittings

Fire-Fighting Hose Fittings

Connect these fittings to fire hydrants and washdown equipment.

Rocker-Lug Fire-Fighting Hose Fittings

The rocker lugs on these fittings allow for easy gripping, so you can quickly connect to fire hydrants and washdown equipment.

Pin-Lug Fire-Fighting Hose Fittings

The pin lugs on these fittings allow for easy gripping, so you can quickly connect to fire hydrants and washdown equipment.

Metal Barbed Hose Fittings for Air and Water

Metal hose fittings have better durability than plastic barbed hose fittings.

Metal Cam-and-Groove Hose Couplings for Water

Metal cam-and-groove couplings have better durability than plastic cam-and-groove couplings.
