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.
- Temperature Range: Not Rated
- Material: 304 Stainless Steel
- Fitting Material: 304 Stainless Steel

Expansion Joints with Butt-Weld Ends
- For Use With: Air, Natural Gas, Oil, Steam, Water
- Temperature Range: -20° to 800° F
- Maximum Pressure: 150 psi @ 72° F
- Maximum Vacuum: 29 in. of Hg @ 72° F
These joints weld to unthreaded pipe or another butt-weld fitting for a leak-resistant, permanent connection. They reduce stress, vibration, and noise in metal piping systems by providing a point of flexibility to absorb movement.

Easy-Clamp Duct Hose for Dry Food
- Flexible
- Compatible Clamps: Worm-Drive and Quick-Release Clamps
- Color: White
- Temperature Range: Natural Rubber: 0° to 180° F; Neoprene Rubber: 0° to 212° F
These short lengths of hose have a collar on each end to prevent the clamp from slipping off. Connect them to sifters, screeners, and other vibratory equipment. FDA compliant for direct contact with food, they’re often used to move rice and grain. Made of either natural rubber or neoprene, this hose won’t impart taste or odors on your product.
Neoprene hose is harder than natural rubber hose but less durable.
Warning: Hose should not be used for applications that generate a static charge.

High-Temperature All-Metal Expansion Joints with Flanged Ends
- For Use With: Air, Natural Gas, Oil, Steam, Water
- Temperature Range: -20° to 800° F
- Maximum Pressure: 150 psi @ 72° F
- Maximum Vacuum: 29 in. of Hg @ 72° F
These all-metal expansion joints can handle higher temperatures than rubber expansion joints. They reduce stress, vibration, and noise in piping systems by providing a point of flexibility to absorb movement. Joints are made of 304 stainless steel for very good corrosion resistance. The flanged ends rotate for easy bolt hole alignment during installation. Flanges mate with a same-size flat-surface Class 150 flange with a gasket (sold separately).
Liners (sold separately) slide into the expansion joint to provide a smooth interior for unrestricted flow.
