304 Stainless Steel—Fittings hold up in humid, damp, and washdown environments but will corrode if exposed to salt water or chemicals.

316 Stainless Steel—Fittings are the most corrosion resistant. They stand up to wet environments, just like 304 stainless steel fittings, but unlike 304 stainless steel, they will not corrode from salt water, chlorine solutions, and chemicals.

Stub-End Straight Adapters

Straight Adapter

Stub-end straight adapters are used with flanges. Slide a flange onto the stub end and weld the stub end to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily, which creates an access point for frequent cleaning and inspecting.

Thick-Wall Plastic Pipe Fittings for Water

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. Fittings are plastic for good corrosion resistance. They meet ASTM specifications and testing requirements for material quality.

To prevent leaks in threaded connections, apply a sealant to the male threads. Threaded connections can be taken apart as needed for maintenance and repair. For metal threads, use PTFE tape. For plastic threads, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.

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

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.

Standard-Wall Plastic Pipe Fittings for Water

Connect these fittings to Schedule 40 plastic pipe–they are the industry standard for residential and commercial low-pressure plumbing and water supply applications. They are plastic for good corrosion resistance.

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

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.

High-Pressure Iron and Steel Socket-Connect 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. 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.

High-Pressure Iron and Steel Threaded Pipe Fittings

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

FM-Approved Low-Pressure Iron and Steel Threaded Pipe Fittings

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.

High-Pressure Iron and Steel Butt-Weld Pipe Fittings

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.

Low-Pressure Aluminum Socket-Connect 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. Slide pipe into the socket and weld for a strong, permanent connection. Fittings are aluminum, which is lightweight with good corrosion resistance.

Low-Pressure Aluminum Threaded Pipe Fittings

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.
