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.
