Think for a moment about the incongruity, the water light of a vessel often relies o something as simple and mundane as a hose clamps, some of that cost less than a dollar. While I can’t say I have seen many vessels sink as a result of a failed hose clamps. There are all the important hoses that hose clamps secure from fuel fill and supply plumbing to sanitation and potable water systems. Hose clamps don’t operate on their own, how to install and connect pipe and hose? It’s important that they, and the hose be used in conjunction with compatible, purpose made pipe to hose adapters. You can find the American type, Europe type and British type hose clamps in market, which are derived from different standards and application. You can find iron, W2,W3,W4 and W5 material, The most popular one in market is W2, the band and housing are made of 430 stainless steel, screw is steel with Cr3+ coating, the breaking torque is about 5 N.m and the price is good for the end user. But for a higher requirement, we suggest you to select W4, all of clamps are made of 304 stainless steel with high corrosion resistance and high breaking torque, but the price is high, too.
