Also known as Schedule 10 fittings, these are thin and lightweight. They have beveled ends that, when flush to pipe, create a trough for a strong weld that permits maximum flow.

304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.

Butt-weld fittings allow for a smooth connection that provides maximum flow. They have beveled ends that, when flush to pipe, create a trough for a strong, permanent weld. Fittings are also known as Schedule 40. They are for use in noncorrosive environments.

With thicker, stronger walls than our standard-wall butt-weld pipe fittings, these fittings stand up to your high strength applications. Weld them flush against pipe for a smooth connection that permits maximum flow. These fittings have beveled ends that create a trough for a leak-resistant, permanent weld. Made of steel, they’re for use in noncorrosive environments.

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn’t need to align perfectly to the pipe. Slide pipe into the socket and weld for a strong, permanent connection. Fittings have heavy duty construction that stands up to high-pressure applications. They are for use in noncorrosive environments.

Use these fittings for low-pressure applications in noncorrosive environments.

Connectors with NPT threads are threaded on both ends.

Female x male 90° elbow adapters are also known as street elbows.

To prevent leaks in low-pressure lines, the male threads on these fittings have an acrylic sealant already applied for extra protection. Also known as Pressure Class 125 or 150 fittings. Made of either iron or steel, they’re best in noncorrosive environments. Even with sealant, threaded connections can be taken apart for maintenance and repair.

Female x male 90° elbow adapters are also known as street elbows.

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. They are also known as Pressure Class 125 fittings. Use in noncorrosive environments.

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

Female x male 90° elbow adapters are also known as street elbows.

These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.

Phosphate-coated and zinc-phosphate-coated fittings offer some corrosion resistance, but aren't intended for corrosive environments.

Note: The maximum pressure listed for Class 3000 fittings is for conditions where there are no sudden changes in pressure or velocity. Please refer to ASME B16.11 to determine the specific maximum operating pressure for your application.

With better strength than our low-pressure iron and steel pipe fittings, these can handle medium-pressure applications. They are for use in noncorrosive environments.

FM approved, these fittings are suitable for use in fire-protection systems. All have flat-surface flanged ends that only mate to another same-size flat-surface flange, pump, or valve with a gasket (sold separately) to create an access point in a pipeline. Use them in noncorrosive areas.

Use these fittings in low-pressure flow applications. They have good corrosion resistance. Fittings rated for use with drinking water meet NSF/ANSI 61 safety standards.

Female x male 90° elbow adapters are also known as street elbows.

Also known as Schedule 40 fittings, these have thicker walls than our thin-wall aluminum unthreaded pipe fittings. They have beveled ends that, when flush to pipe, create a trough for a strong weld that permits maximum flow. Fittings are lightweight with good corrosion resistance.

Also known as Schedule 10 fittings, these are the thinnest aluminum pipe fittings we offer. They have beveled ends that, when flush to pipe, create a trough for a strong weld that permits maximum flow. Fittings are lightweight and have good corrosion resistance.

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn’t need to align perfectly to the pipe. Slide pipe into the socket and weld for a strong, permanent connection. Fittings are aluminum, which is lightweight with good corrosion resistance.

Thick walls give these Schedule 80 fittings excellent strength. They have beveled ends that, when flush to pipe, create a trough for a strong weld that permits maximum flow. Fittings are aluminum, which is lightweight with good corrosion resistance.

In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications. To prevent cracking, do not tighten more than a 1/4-turn past hand tight.

Female x male 90° elbow adapters are also known as street elbows.

Fittings weld flush against pipe, creating a strong connection that permits maximum flow. Fittings are also known as Pressure Class 200 fittings. They are copper-nickel, which has excellent resistance to stress cracking and better corrosion resistance than most stainless steel alloys. They are often used in highly-corrosive environments, such as salt water applications.

Made of CPVC, these fittings can handle high temperatures. They have thick, strong walls to handle heavy duty industrial plumbing and water supply applications, such as water processing and waste water treatment. They also have good corrosion resistance. These fittings are comparable to Corzan. Some meet ASTM D1784 specifications and testing requirements for material quality.

Fittings for drinking water meet NSF/ANSI Standard 61.

Schedule 80 fittings have thick, strong walls for heavy duty, industrial applications.

Note: For fittings that are not rated for pressure, you can use the pressure rating of the plastic pipe as a reference. Threaded fittings are limited to 50% of the rated pressure of the pipe.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

Sealants cannot be sold to Colorado, Connecticut, District of Columbia, Delaware, Illinois, Indiana, Massachusetts, Maryland, Maine, Michigan, New Hampshire, New Jersey, Northern Virginia, New York, Ohio, Pennsylvania, Rhode Island, or Utah due to local regulatory limits on VOCs (Volatile Organic Compounds).
