Flexible
Compatible Clamps: Worm-Drive Clamps
Color: Black or Red
Temperature Range: Neoprene Coated: -65° to 300° F; Silicone Coated: -75° to 500° F

Combining the heat resistance of metal with the flexibility of fabric, this fiberglass hose has a special coating that stands up to high temperatures. Hose is for use with smoke, water-based paint fumes, and welding fumes.

Neoprene-coated hose meets UL 94 HB and UL 94 V-0 for flame retardance and can also handle sparks.

Silicone-coated hose handles a wider temperature range than neoprene-coated hose.

Multipurpose 304 Stainless Steel

From cookware to chemical-processing equipment, 304 stainless steel is a good all-around choice for a wide range of applications. It maintains its corrosion resistance in temperatures up to 1500° F.

304/304L stainless steel contains less carbon than standard 304 for better weldability.

Seamless round tubes are more corrosion resistant than welded tubes because they don’t have a seam that could potentially introduce impurities.
