High-Pressure Smooth-Bore Seamless Titanium Tubing
- Temperature Range: -20° to 600° F
- Bending Method: Tube Bender
Seamless construction with no weld bead gives this tubing a smooth interior for unrestricted flow. It is stronger than welded tubing and can be flared without splitting. Tubing is lightweight with excellent corrosion resistance. It connects by welding.

UV-Resistant Polypropylene Pipe for Chemicals
This polypropylene pipe resists the damaging effects of ultraviolet light, so it’s suitable for outdoor use. It has the chemical resistance to withstand a wide variety of acids, solvents, and other harsh substances. Pipe has thick, strong walls for heavy duty chemical processing applications. It meets ASTM D4101 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.
Pipe that meets ASME B1.20.1 adheres to quality specifications for thread dimensions.
