The marine version of the clamp uses a stainless-steel band and screw, eliminating the rust problem. However, in spite of its all-stainless construction, these clamps remain susceptible to crevice corrosion, a form of failure peculiar to stainless steel. (See "Beware of Stainless-Steel Corrosion," May 2009.) If the clamp is exposed to stagnant, oxygen-depleted water-say, for example, in the bilge-corrosion can set in, causing the clamp's band to part. This type of failure is especially common on stuffing boxes. The insidiousness of the corrosion is that it occurs on the bottom of the clamp, beneath the stuffing-box hose, where it can't readily be seen. I've encountered this type of failure many times; the clamp looks pristine, but when it's pulled on, it simply falls off.
