Vacuum Hose Connectors

Since I was not able to find well made hose connectors with buttons anywhere on the market (at least at reasonable price) I decided to create my own models. I uploaded hose connectors with different connector diameters (32, 45, 50), hose diameters (32, 35, 38, 45, 50) and smooth tip diameters, both socket and nipple versions (32, 40, 50), that are compatible with each other within the same connector diameter. Using these for almost a year with my central vacuum cleaner.
