Thick-Wall Aluminum Threaded Pipe Nipples and Pipe

Also known as Schedule 80, this pipe has extra-thick walls to handle high-pressure applications. It is aluminum, which is lightweight with good corrosion resistance.

Pipe—Fully Threaded

Male

Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.

Seamless—Pipe has a smooth interior for unrestricted flow and is stronger than welded pipe.

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.

Saddle Tap Tees with Collar and Gasket

Female x Clamp On

Saddle-tap tee adapters allow you to create additional outlets and connections in metal or plastic pipe. To install, shut down your line and drill a hole in the pipe where you want to create a connection. Position the saddle over the hole so the gasket and lip are fully engaged and secure with the included nuts, bolts, and washers.

Fittings with collar have a stainless steel reinforcement on the female threads to prevent the threads from cracking.

NSF/ANSI 61—To adhere to safety standards for drinking water systems, use pipe that meets NSF/ANSI 61.
