Flexible Steel Hose & Hose Clamps

Hose Clamps

flexible hose clamps

Bridge Clamps

flexible hose bridge clampsFor clear polyurethane and black heavy duty (HD) flexible hose only. 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.

Table 34-1: Hose Clamp Sizes
No. Range
02HC 1-13/16 – 2-3/4″
03HC 2-9/16 – 3-1/2″
04HC 3-1/2 – 5-1/2″
05HC 4-1/2 – 6-1/2″
06HC 5-3/4 – 7-3/4″
07HC 6-1/2 – 8-1/2″
08HC 2 – 10″
10HC 9-1/2 – 11-1/2″
12HC 11 – 13″
14HC 12-1/2 – 14-1/2″
16HC 15-3/8 – 17-3/8″
18HC 18 -20

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.

Steel Flexible Hose

steel flexible hoseSteel flexible 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.
