Quick-Connect High-Vacuum Fittings for Stainless Steel Tubing
Twist these fittings onto high-vacuum tubing to quickly make sealed, high-vacuum connections without the need for clamping, welding, or tools. To connect, insert your tubing into the fitting and twist the collar on the end of the fitting; an O-ring on the inside of the fitting compresses to form the seal. Also known as quick-disconnects, they're as easy to twist off as they are to twist on. Not for use in pressure applications.
Adapters have a quick-connect fitting on one side and a quick-clamp fitting on the other. Use them to attach and remove components for one-off uses or to adapt your quick-clamp system to connect to glass tubing. Quick-clamp fittings are also known as KF, QF, and NW fittings; they require a clamp and ring (sold separately) to complete the connection.

- Maximum Vacuum: 29" of Hg @ 72° F
- Material: Buna-N Rubber Blend with Blended Rubber Cover
- Color: White
For easy access to lines that handle oily and fatty foods and beverages, this hose has flanged ends that join with quick-clamp fittings. Both the hose and fittings are 3-A certified for safe use with food, and the hose is also FDA compliant. Made of a Buna-N blend, this hose remains flexible even when exposed to oil. A smooth interior prevents food from getting caught and building up. 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. They attach to other quick-clamp fittings with a gasket and a clamp.
