Vacuum Fittings for Steel Tubing
- For Use With: Air, Glass, Plastic Pellets, Resins, Wood Chips
- Temperature Range: -10° to 180° F
- Tubing: Galvanized Steel: Use with steel, galvanized steel
Steel: Use with steel
Use these fittings to create an air vacuum system without the hassle of brazing and welding. Insert two fittings into a clamp (sold separately) and tighten to form a secure seal.
Galvanized steel fittings have fair corrosion resistance. Fittings without a finish should only be used in noncorrosive environments.

Clamps for Vacuum Fittings for Steel Tubing
Use these clamps to connect vacuum tube fittings. Insert two fittings into a clamp and tighten to form a secure seal.
For technical drawings and 3-D models, click on a part number.
- For Use With: Air, Glass, Plastic Pellets, Resins, Wood Chips
- Temperature Range: Neoprene Rubber Gaskets: -20° to 190° F
Silicone Rubber Gaskets: -100° to 500° F - Tubing: Use with steel
Bolt clamps have a stainless steel strip that provides an escape route for electrostatic buildup when used in a fully-grounded system. They have fair corrosion resistance.

Sanitary Snap-In Duct Hose and Fittings
- Flexible
- Color: Clear
- Temperature Range: See Table
Transfer material from sifters, feeders, and strainers to other parts of your sanitary line with these hose lengths and fittings. They’re 3-A and USDA certified to meet sanitary design standards, as well as FDA compliant for direct contact with food. Cuffs at each end of the hose have grooves that snap into matching grooves on fittings. These grooves form a seal that’s more sanitary than hose clamp connections, since there are no gaps where contaminants could gather. It’s also tighter and less likely to leak than hose clamps. When pressure increases, the hose presses against fittings, tightening the seal. You don’t need tools to install or remove this hose—squeeze the end cuff to slide it into or out of fittings.
Made from flexible, abrasion-resistant plastic, this hose won’t crack and rip from the movement of your machines. It’s also chemical-resistant, so it holds up to frequent washing during clean-in-place (CIP) cycles. The smooth seams won't trap food and other particles. It's clear, so you can monitor flow.
When choosing a hose length, consider the side-to-side, horizontal, and rotational movement of your machines. You’ll need hose that’s slightly longer than the gap between equipment to account for movement and vibration.
Hose with 1" coil is good for applications with up-and-down movement, such as bag feeders. The closely-spaced internal coil helps the hose maintain its shape while it’s compressed.
Hose without coil has thick, flexible walls that bend side-to-side to handle misalignment and rotation. It’s often used with sifters and strainers. This hose doesn’t handle up-and-down movement as well as hose with 1" coil, since the walls may crease when the hose is compressed. Creases in the hose wall restrict flow, increase wear, and create pockets that trap food and liquids. This hose is latex-free and doesn’t include Bisphenol A (BPA), which is a chemical that can contaminate your line.
Fittings are stainless steel, which won’t corrode from harsh cleaners and sanitizers. You can cut them to fit onto existing pipes. Weld them to the inlets and outlets on your equipment before attaching hose.

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.
