High-Temperature Air Hose
Also known as hot air blower hose, this hose stays flexible and strong as it transfers compressed air at temperatures above 300° F. It’s often used to pressurize storage tanks, where hot, compressed air can prevent dry bulk materials from clogging and sticking during unloading. If used in a grounded system, it has a steel wire that gives electrostatic buildup a path to escape. Along with synthetic fabric, this steel wire reinforces the hose, so it keeps its shape under pressure. Made of EPDM, this hose resists UV rays and ozone and can be used outdoors.
Food industry hose is FDA Compliant, so it's safe for use with dry food.

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.

Metal Barbed Hose Fittings for Air and Water
Slide the barbed end into rubber hose and secure with the appropriate clamp or crimp-on hose ferrule.
Brass fittings are softer than other metal fittings, so they’re easier to thread together. Plain brass fittings have good corrosion resistance.Bronze fittings have better corrosion resistance and are stronger than brass and aluminum fittings.Aluminum fittings are lighter in weight than other metal fittings. They have good corrosion resistance.
Stainless steel fittings have very good corrosion resistance. 303 stainless steel fittings won’t rust when exposed to water, making them good for areas that require frequent cleanings. Fittings that swivel until tightened rotate 360° for easy installation. Fittings with a threaded end are also known as hose nipples.
Hose connectors are also known as hose menders and splicers. Use them to connect lengths of hose or to repair damaged hose.
Female NPSM (National Pipe Straight Mechanical) threads are compatible with male NPT and NPTF threads. Male NPSM threads are compatible with female NPSH threads.

Easy-Fit Barbed Hose Fittings for Air and Water
Low-profile barbs and a longer first barb allow for a smoother, easier installation than other barbed fittings. Slide the barbed end into rubber hose and secure with a clamp.
Steel fittings are stronger and more durable than other metal fittings. They should be used in noncorrosive environments. Zinc-plated steel fittings have slightly better corrosion resistance than unplated steel fittings. Aluminum fittings are lighter in weight than other metal fittings. They have good corrosion resistance. Brass fittings are softer than other metal fittings, so they’re easier to thread together. They have good corrosion resistance.
Fittings with a threaded end are also known as hose nipples.

High-Polish Metal Quick-Clamp Sanitary Tube Fittings
- Temperature Range: See Gaskets
The smooth finish inside these fittings makes it easy to remove product residue. Also known as aseptic and tri-clamp fittings, they connect with a gasket, a clamp, and another quick-clamp fitting for a fast and easy way to access your line. The pressure rating of the fitting will vary depending on the clamp you choose, and the temperature rating will vary based on the gasket material you choose.
304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.
Note: To complete a connection, you’ll need two quick-clamp fittings, a clamp, and a gasket (all sold separately).
- For Use With:
3-A Certified Fittings: Air, Beverage, Food, Water

Insulated Bend-and-Stay Metal Duct Hose for Air
- Very Flexible
- Compatible Clamps: Worm-Drive Clamps
- Color: Silver
- Temperature Range: -100° to 435° F
Bend this hose into position in heating and cooling applications where it’s important to maintain the temperature of the air inside the hose. Unlike fabric duct hose, this lightweight aluminum hose holds its shape once it’s curved around corners. It’s insulated with a layer of fiberglass, so it keeps air flowing through at a consistent temperature even when it’s routed through hot or cold spaces. The metalized film cover seals out moisture, protecting the insulation underneath.
This hose is not meant to be continuously flexed. Lengths beyond 6 ft. may need support.
