I have duravent piping with hose clamps at each connection (built in). Having leaking issues smoking ect. I replaced the silicone seals at every connection but the hose clamps just slip and will not tighten, tried adjusting the worm screw by moving the clamp and clamping it with a hand clamp no go still won't grab to tighten. what is the next move? Can I just buy some SS clamps remove the old ones and insert new ones inside like they are designed? obviously placing a clamp just on the outside is point less. I feel this is a terrible design honestly. I am a auto tech of 15 years, so im well aware of the life span of your SS hose clamps!! any help is appreciated thanks.
