A bolted interlocking hose clamp is the most secure way to install interlocking ground joint type hose couplings. The top of the clamp has fingers that interlock with a ring on the hose couplings. The clamp features 2, 4, or 6 bolts depending on hose diameter. 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.
The inside diameter listed must match the hose size, and the hose outside diameter must fall into the range listed. Do not select a clamp that does not match inside diameter of the hose in order to have it fall in the OD range or vice versa.
-When installing, tighten evenly, half tight one side, then half tight the other side, alternating top and bottom, as you would tighten wheel lugs on a car.
Do not replace bolts with standard bolts, these are designed to bend slightly upon installation. Do not re-use bolts if they are no longer straight. Check torque regularly to ensure that the coupling is safely installed. Ensure that the bolts are on the right side of the clamp shell - a tab on the shell lines up with the bolt-head to hold it in place.
