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

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.

The threads on these fittings have clockwise (right-hand) threads on one end and counterclockwise (left-hand) threads on the other end.

Use these Pressure Class 150 pipe flanges in low-pressure lines where temperatures drop down to -40° F.

Suitable for use in fire-protection applications, these pipe fittings are made of cast iron, so they are brittle and can be quickly opened with the strike of a sledge hammer.

The galvanized finish on these Pressure Class 150 flanges provides fair corrosion resistance.

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

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

A plastic sleeve prevents destructive corrosion when connecting different metals.

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

A galvanized finish gives these fittings fair corrosion resistance. They have the strength to handle medium-pressure applications.

Also known as Pressure Class 300 flanges, these medium-pressure flanges have a galvanized finish for fair corrosion resistance.

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

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

The strongest steel fittings we offer, these can withstand extreme-pressure applications.

These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces.

Bolt two flanges of the same size together with a gasket to create an access point in a pipe line.

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

Even in temperatures as low as -46°, these A350 LF2 steel flanges won’t become brittle, so they absorb impact better than other low-pressure steel flanges.

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slide the pipe into the socket and weld.

For excellent strength in extreme-pressure applications, choose these heavy duty Pressure Class 1500 flanges.

Also known as Pressure Class 150 flanges, these brass flanges are designed for low-pressure applications.

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

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

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

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

Bolt these flanges to another same-size flange with a gasket to create an access point within a pipe line. They are also known as Silbraze flanges.

Bolt two same-size flanges together with a gasket to create an access point within a pipe line.

Press these fittings onto stainless steel pipe using a crimping tool for a permanent, leak-tight connection that's faster than threading or welding and doesn't require heat.

Typically used with thin-wall stainless steel unthreaded pipe fittings.

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slip the pipe into the socket and weld.

Use these heavy duty forged flanges for high-pressure applications.

Typically used with medium- to high-pressure stainless steel threaded pipe fittings.

Choose these fittings when you want the same high-quality found in our low-pressure pipe fittings, but need more strength to handle higher pressures.

Unlike other stainless steel fittings, these are made in the U.S.A. for superior quality. As another marker of quality, they come with a certificate with a traceable lot number and test report that guarantees material composition.

Use these corrosion-resistant fittings in a low-pressure pipe line.

Typically used with low-pressure stainless steel threaded pipe fittings.

Keep a variety of lengths of pipe and pipe nipples on hand for areas where corrosion is a concern.

Their small size makes these miniature fittings a good choice for cramped, confined spaces.

Typically used with high-pressure aluminum threaded pipe fittings.

Typically used with low-pressure aluminum threaded pipe fittings.

Twist these fittings onto aluminum pipe for quick, sealed connections—no threading, soldering, or welding necessary. Use them to build a compressed air system in half the time it would take to build a copper or steel system.

Also known as Schedule 40 fittings, these have thicker walls than our thin-wall aluminum unthreaded pipe fittings.

Thick walls give these Schedule 80 fittings excellent strength.

The inside of these fittings won’t leach contaminants into your line or accumulate particles—they’re polished to an ultra-smooth 12 Ra finish, which also makes it easy to clean. Made of polypropylene, they resist organic solvents, acids, and alkalis better than CPVC fittings.

Connect these fittings to Schedule 80 pipe. With thicker, stronger walls than standard-wall fittings, they can handle heavy duty supply applications, such as water processing, wastewater treatment, and irrigation.

Solder these fittings to tubing for a permanent, leak-tight connection. They are also known as sweat fittings.

When cleanliness is crucial to your application, choose these fittings that are individually cleaned and bagged to prevent contamination.

The flat face of the fitting connects to a tube adapter so you can slide the tubing and fitting sideways to disconnect in cramped spaces. They are also known zero-clearance fittings.

Use these fittings at pressures up to 9,700 psi. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

These fittings have two sleeves for extra gripping power. They bite into steel tubing as you tighten the nut to form a strong seal.

These Monel fittings have the corrosion resistance to handle hydrofluoric and sulfuric acid. Also known as instrumentation fittings, they include a nut with two sleeves.

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.

To keep contaminants out of your gas line, add these dust caps and plugs to natural and LP gas couplings when they’re not connected. All work with couplings that are rated ANSI Z21.41/CSA 6.9 for use with gas fuel appliances.

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.
