Hose Bands Extra Heavy Duty / Hose Bands Double Bolt Type
-
Hose Bands Double Bolt Type provide an efficient means of securing couplings for low pressure discharge or suction service. Double bolt hose clamps are sized for hose OD from 30mm to 300mm .
-
As the bolts are tightened, the double-tongue saddles fill the gap between the bolt lugs preventing pinching of the hose OD.
-
The inside of the clamp shells have serrations that press into the cover of the hose for increased grip. Hose can change in diameters over long term pressurization.
-
The bolted clamp allows for adjustment. Torque should be checked on these clamps to ensure that the coupling stays tight.Use of lubricant on bolts will adversely effect clamp performance .
- Fully tightened, the double bolt clamps secure the full circumference of the hose.
-
Please measure hose outer diameter (OD) accurately before ordering clamps.
