Frequently Asked Questions

Q. "How do I determine the overall lengths of the hose clamps you offer?"
A. Take the largest diameter shown for a given clamp and multiply times pi (3.14) to get an approximate length.

Q. "You say these are marine grade, so I can use them underwater on my boat, right?"
A. These are top quality, all stainless steel hose clamps perfect for corrosive applications exactly like underwater on a boat. Just remember, however, that underwater on a boat you'll always want to double clamp (use two clamps) and make sure both clamps are solidly over hose and the shaft underneath.
