High-Vacuum Exhaust Hose with Quick-Clamp Fittings
Connect to high-vacuum pumps to route exhaust fumes out of your work area. Also known as roughing hose. This hose is equipped with quick-clamp (KF) fittings; a clamp and a ring (both sold separately) are required for each fitting. Hose is flexible so you can snake it around equipment. It's reinforced with wire to prevent it from collapsing. Not for use in pressure applications.

Abrasion-Resistant High-Vacuum Hose with Quick-Clamp Fittings
A braided exterior protects this hose from abrasion and over-bending. Also known as bellows, the ribbed interior makes it flexible enough to connect high-vacuum components that aren't directly aligned. It also reduces vibration between components such as pumps, valves, and chambers. Connect to your components with the quick-clamp (KF) fittings; a clamp and a ring (both sold separately) are required for each fitting. Not for use in pressure applications.

High-Vacuum Hose with Claw-Clamp Fittings
More flexible than rigid stainless steel tubing, this hose allows you to link high-vacuum components that are misaligned. Also known as bellows. The ribbed design absorbs vibration so it doesn't transfer from one component to the next. Equipped with a claw-clamp (ISO-K) fitting on each end, this hose connects to large components with fittings starting at trade number 63. Each fitting on the hose requires four claw clamps and a ring (both sold separately) to connect. Not for use in pressure applications.
Double-claw clamps attach to the grooves on the fittings.
Single-claw clamps have a clamp on one end and an exposed bolt on the other. Thread the bolt-end directly into the body of pumps, valves, or other high-vacuum components.
