Quoting an oil mist collection system? The next time your customer hits you with an oil mist application here’s a quick check-list of questions to ask: Does this system need to be 100% leak free? Meaning, what happens if the system has occasional drips or leaks – especially when turned off? If the answer means that no leaks are tolerable, then consider a leak free solution like flange and gasket connections or US Tubing (a leak free clamp-connect option).
