High-Temperature PTFE Pipe Nipples and Pipe for Chemicals
- For Use With: Deionized Water, Hydrochloric Acid, Solvents
- Temperature Range: -450° to 550° F
- Specifications Met: ASTM D1710
- Fittings: Use Schedule 80 PTFE Plastic
- Flanges: Use Class 150 PTFE Plastic
This PTFE pipe can withstand a wider temperature range than any of our other plastic pipe for chemicals. It has the chemical resistance to stand up to acid and solvents. 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.

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