2 3/16" Tubing | McMaster-Carr

Also known as furnace door hose, this water hose has a resin-coated fiberglass cover that withstands intermittent extreme heat and splashes of molten metal and glass. The cover also won’t conduct electricity. It’s often used to move cooling water in steel mills, glass plants, and foundries. Reinforced with cords, this hose keeps its shape under pressure.

With a tough EPDM cover, this hose won’t wear down from rubbing or scraping, crack from ozone, or degrade from UV light. It has flanged ends that join with quick-clamp fittings, so you can easily access lines that carry milk, syrup, meat, and other wet food and drinks. You know this hose is safe to use with food because it’s FDA compliant and its fittings are 3-A certified. Made of butyl, it won’t impart tastes or odors to food and beverages as they pass through your line. Both the hose and fittings withstand high temperatures and mild cleaning solutions, so you can clean your line often. Reinforced with yarn and steel wire, this hose holds its shape and won’t collapse when hooked up to a vacuum pump.

The fittings are also known as tri-clamp fittings. Attach them to other quick-clamp fittings with a gasket and a clamp.

Ultra-High-Vacuum Hose with Flanges

Often found in semiconductor manufacturing and other demanding industrial applications, this hose handles nearly perfect vacuum. Sharp edges on the flanges dig into a copper gasket (sold separately) as you bolt the flanges together, creating a tighter seal than fittings with a rubber gasket. This allows the hose to maintain the ultra-high vacuum necessary for vacuum coating, heat treating, leak testing, and analyzing gases. The flanges are commonly referred to as ConFlat (CF) and UHV fittings. Thanks to its ribbed interior, this hose is flexible enough to connect misaligned components. That's why it's also called a bellows. The ribbing reduces vibration between components, such as vacuum pumps, valves, and chambers. Both the hose and flanges are made of stainless steel, so they resist rusting.

One of the flanges rotates, so you can easily match up the bolt holes with another flange. Make sure your mating flanges are the same size as these flanges.

Bolt kits are required to make a complete connection.
