Plastic Barbed Hose Fittings for Water
Made of polypropylene, these fittings have good corrosion and abrasion resistance, and are lighter in weight than metal barbed hose fittings. Slide the barbed end into plastic or rubber hose and secure with a clamp.
Fittings with a threaded end are also known as hose nipples.
Hose connectors are also known as hose menders and splicers. Use them to connect lengths of hose or to repair damaged hose.

Standard-Wall Plastic Pipe for Water
Connect this pipe to standard-wall plastic pipe fittings for a variety of residential and commercial low-pressure plumbing and water supply applications. It’s made of PVC, which has good corrosion resistance. Pipe meets NSF/ANSI Standard 61 for drinking water. It also meets ASTM D1784 and ASTM D1785 specifications and testing requirements for material quality. Connect this pipe to unthreaded female socket-connect fittings using a PVC primer and cement (also known as solvent weld).
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.
Low-Carbon Steel Round Tubes
Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength, such as frames, supports, and conduit. This steel is manufactured to ASTM, SAE, or EN standards for quality and performance.
Seamless tubes are stronger than welded tubes.
Ultra-High-Temperature Quartz Glass Tubes
- Color: Clear
- Max. Temperature: 2000° F
- Fabrication: Annealed
Blistering temperatures won’t melt these quartz tubes, and rapid temperature shifts won’t cause them to crack. Even tougher than borosilicate, they can be used in furnaces and ovens heated up to 2000° F. These highly pure tubes are often used in laboratories because they won’t leach impurities into samples or contaminate chemical reactions. Quartz tubes are optically clear and have excellent UV transmission, making them ideal for UV purification systems.

Standoff Strut-Mount Metal Routing Clamps
Hold pipe, tubing, and conduit away from strut channel. To install, slide the clamp into the strut channel and tighten the clamping screw to secure. Clamps are zinc-plated steel for good corrosion resistance.

Strut-Mount Vibration-Damping Routing Clamps
Slide multiple clamps into existing strut channel to organize lines of pipe, tubing, and conduit without the need for drilling, welding, or using adhesive. Clamps have a plastic or rubber cushion or body to reduce vibration.
Zinc-plated steel and stainless steel clamps with TPE cushion resist most oils, chemicals, and cleaning compounds. With a metal body, they provide a more secure hold than TPE clamps. Slide into strut channel and fasten the nut to secure. Stainless steel clamps are more corrosion resistant than zinc-plated steel clamps.
Polypropylene clamps are good for hydraulic applications. To install, slide into strut channel and fasten the mounting bolts into the included strut channel nuts. Clamps with 316 stainless steel top plates are more corrosion resistant than clamps with steel top plates.
Glass-filled nylon clamps with SBR cushion are good for refrigeration, HVAC, and hydraulic applications. Their plastic construction prevents corrosion caused by metal-to-metal contact. Slide into strut channel and fasten the nut to secure.
Stacking clamps allow you to route multiple lines with different diameters on top of each other. They include fasteners and a plate for attaching to regular clamps or other stacking clamps. Stacking clamps cannot be used alone.
