Extra-Thick-Wall Steel Threaded Pipe Nipples and Pipe
Extra-thick walls give this pipe excellent strength to handle high-pressure applications. It is also known as Schedule 160. Pipe is seamless, so it has a smooth interior for unrestricted flow. A phosphate coating gives this pipe some corrosion resistance, but it shouldn’t be used in corrosive environments.
Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.

Hook-and-Loop Wrap-Around Sleeving for Universal Robots
Organize and protect the cables and tubing on your Universal Robots arm without hindering its movement. This sleeving is made for Universal Robots arms, so you don’t need to measure, cut, or customize for a good fit. The hook-and-loop closure makes installation quick, and unlike cable ties, it’s easy to detach and adjust. Cables run through a separate channel, so you can access them without removing the sleeving from your arm. Made from polyurethane, this sleeving is flexible enough for cables and tubing to move easily, and durable enough to withstand continuous movement. It’s also lighter than hose carriers and conduit, so it won’t weigh down your robot arm. Each includes two pieces of sleeving.

Fiberglass Pipe Insulation
This common insulation material is typically used on hot and cold water lines and in process piping. To use outdoors, add metal jacketing.
Tubes, elbows, and tees are formed to provide the best fit on pipe and are the easiest to install. If your pipe is larger than the sizes we offer, choose a sheet/strip.
Tubes have an all-service jacket (ASJ) made of kraft paper with an adhesive strip closure. Seal with reinforced insulation tape (sold separately).
