Extreme-Temperature Air and Steam Hose with Flanges
- Temperature Range:
316 Stainless Steel Hose: -325° to 1200° F
321 Stainless Steel Hose: -20° to 950° F - Maximum Vacuum: 29in. of Hg @ 72° F
- Material: 316 Stainless Steel or 321 Stainless Steel
Braided stainless steel construction gives this hose moderate flexibility and makes it tough enough to handle extreme temperatures, as well as vibration. Bolt the flanged ends to pumps and tanks. You’ll need a gasket to seal the connection. Flanges that swivel until tightened are easy to align with bolt holes.

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.
