Refrigerant Hose
- Temperature Range: -40° to 280° F
- Maximum Vacuum: 28 in. of Hg @ 72° F
- Material: Nylon Plastic with EPDM Rubber Cover
- Color: Black
- Compatible With: Danfoss EZ Clip
Made of nylon, this hose keeps refrigerant in but moisture out, protecting your air conditioning or refrigeration system from freezing or corroding. It stays strong and flexible across the wide range of temperatures common to cooling applications. Safe for use outdoors, it has an EPDM cover that protects it from ozone and UV damage. It meets SAE J3062 Type E, so it won't become brittle and crack from most common refrigerants and oils used in automotive air conditioning.
You’ll need hose clamp pliers and refrigerant fittings to make a hose assembly.

No need for expensive crimping tools—these fittings make air conditioning and refrigeration assemblies with clamps. Instead of a crimper, they use two clamps that you tighten against a cage on your fitting with pliers. Both fitting ends swivel until tightened, so you don't have to rotate the entire hose during installation. The cage and clamps stretch out after use, so they shouldn't be used again.
Straight adapter kits include everything you need to connect one end to aluminum tubing. Braze the fitting to your tube with one of the braze rings. To prevent leaks, slip an O-ring on after the brazed joint cools. To connect these fittings to a hose, you’ll need a cage, clamps, and hose clamp pliers.
Fittings with an O-ring pilot create a leak-tight seal, so they’re often used in commercial and vehicle air conditioning systems. When you screw the fitting onto your tube, the bead and the pilot squeeze the O-ring, which fills in any gaps. The pilot also helps guide your hose onto the fitting, making it easy to properly align and secure the connection.
Fittings with a 45° flared end are also known as SAE fittings.

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.
