Aluminum Quick-Connect Pipe for Compressed Air
- For Use With: Air, Coolant, Nitrogen, Oil
- Maximum Pressure: 230 psi @ 72° F
- Specifications Met: ASTM B241
- Fittings: Use Quick-Disconnect Aluminum
Build a compressed air system in half the time it would take to build a copper or steel system. Also known as Unipipe, this pipe is part of a quick-connect system. The compatible fittings connect to this pipe when you finger tighten their collar and then use a wrench for the final quarter turn. A compression ring and O-ring inside the fitting seal it onto this pipe.
Choose blue or gray pipe for easy identification. Blue pipe is often used for compressed air systems. Gray pipe is often used for vacuum systems.
Use a deburring scraper (sold separately) to smooth rough edges left behind after trimming the pipe to size.
Place the tool over the end of your tube and twist to deburr.

Also known as Schedule 80 pipe, it has thick walls for heavy duty industrial applications. The material won’t leach contaminates into the line, so this pipe is commonly used in high-purity processes, such as semiconductor and clean room applications. It has a super-smooth interior for unrestricted flow. Pipe meets ASTM D1710 specifications and testing requirements for material quality.
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 VOC (Volatile Organic Compounds) regulations.
Cut threads in both ends of these pipes to create nipples that thread into PTFE fittings. To prevent leaks in threaded connections, apply a non-hardening, plastic-compatible sealant to the male threads. Tape or sealants with PTFE are not recommended for plastic-to-plastic threaded 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.
