Hose Clamps

Good quality hose clamps last much longer than cheap ones. Look for clamps that are 100 percent stainless steel, including the screw. The best ones are non perforated rather than slotted. Clamps that are embossed rather than perforated are much stronger and longer lasting. It's tempting to think that stainless steel does not rust, but it does, especially when in contact with deoxygenated water, such as that found trapped between a clamp and the hose it is holding.

Use the best marine-grade 316 stainless steel hose clamps. Replace any that are even slightly rusted, and double-clamp critical hoses. Band-type clamps are the best choice for exhaust hoses as they are wider and are tightened with a bolt rather than a screw.

Tip: You can perform a quick check of hose clamps with a magnet. Quality hose clamps will be nonmagnetic. Cheaper hose clamps may have a regular mild steel screw and should be rejected, even if the remainder of the clamp is made from stainless.
