McMaster-Carr Polypropylene Fittings

Anyone use the polypropylene fittings from McMaster-Carr? I am curious to see how they hold up in the long haul compared to Banjo fittings and cam locks. Their prices seem a lot cheaper too when buying a lot of fittings. I have used McMaster for work buying high pressure fittings for pressure vessels, but never thought to look up parts for use in pressure and soft wash applications. Everything I have ever ordered from them came in 2 or 3 days unless there was a lead time on the material. I know they’re incredibly reputable and have an amazing online catalog to navigate through different sizes, so I’d really like to try out their poly fittings. They also have Nylon and PVDF materials rated for chemicals and fuel. I’m not really sure the difference for SH applications.
