Flexible Steel Hose & Hose Clamps

Hose Clamps

flexible hose clamps

Bridge Clamps

flexible hose bridge clampsThese clamps are designed only for a black heavy duty and clear polyurethane flexible hose. Bridge clamps produce a tight seal on a standard right-hand spiral wire flex hose. Type 301 stainless is steel is used for the housing and band. The band is 0.025” thick and 1/2″ wide. The screw material is Type 305 stainless steel.

03HC 2-9/16 – 3-1/2″
04HC 3-1/2 – 5-1/2″
05HC 4-1/2 – 6-1/2″

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 manufactured from hot-dipped, galvanized carbon steel and is strip-wound interlocked. You can choose between two different gauge thicknesses based on the type of service required. This steel flexible hose has a temperature rating up to 788° F and may be twisted but will not unravel. We suggest an operating temperature no greater than 400° F with this hose. The hose is extended fully when sold, but may have a shorter length than specified if compressed. As a galvanized steel all-metal blower and suction hose for fume and dust collection, it is an ideal option for wood shop molders.

From a completely collapsed position, the tubing may be lengthened 2.5” per foot when subjected to a 25 lb. to 45 lb. tension load. The flexible hose may be used in systems in a semi-compressed condition, halfway between fully compressed and fully extended.
