Flexible Clear Polyurethane Hose (LD)

Flexible clear polyurethane hose is tough and durable, and suitable for a wide variety of applications.

HD Flex Hose Disconect

Hose Coupling

J-Lock Coupling

Typical machine application

Warning: To reduce the risk of static discharge igniting suspended particulates, the flex hose helix wire must be grounded to both the duct system and the machine as shown above.

• Construction: Light duty clear polyurethane wall hose construction reinforced with a spring steel wire helix.

     • Excellent compressibility
     • Cut, gouge, and chemical resistant
     • Efficient flow characteristics
     • Designed for wide temperature ranges
     • Maximum flexibility and abrasion        resistance
• Applications: Recommended for industrial air movement, fume control, and dust collection applications.
• Temperature Range: -65° F to 225° F
• Diameter Range (Inches I.D.): 2"-18" (Available to 24")
• Standard Lengths: 10, 15, and 25 Feet
• I.D. Tolerances (Inches): Up to 8": -0.00 to +0.125; 8" and over: -0.00 to +0.250 Inch
• End Finish: Plain Cut
• Standard Color: Standard LD color: clear                                  Standard HD color: black
• Wall Thickness: LD = .020
                                 HD = .054

Bridge clamps provide a tight seal on right-hand (standard) spiral wire flex hose. Band and housing are Type 301 stainless steel. Band is 1/2" wide and 0.025" thick. Screw is Type 305 stainless.

Bridge Clamps

Note: To determine the spiral direction of your hose, look at the end of the hose. If the spiral goes away from you in a clockwise direction, then the hose has a right-hand spiral.

Flexible Steel Hose

Flexible steel hose is strip-wound interlocked and
made from hot-dipped galvanized carbon steel. There
are two different gauge thicknesses to choose from,
depending on the severity of service. It can be twisted
without unraveling. Steel flex is rated to 788° F. Spiral
Manufacturing suggests that operating temperature
not exceed 400° F. It is sold fully extended and may be
less than specified length if compressed.

Galvanized steel all metal suction and blower hose for
dust and fume collection. An excellent choice for wood
shop molders.

From fully collapsed, tubing can be extended 2.5’’ per foot under a tension load of 25-lbs. minimum to 45-lbs. maximum. Install in systems in semicompressed condition, midway between fully extended and fully compressed.
