Thanks Valkyrie! I have been making my own systems for years. It's and engineer thing! lol I have a pump, an automotive brake bleeder pump but i rarely use it. i can draw 4 to 5 negative PSI with my mouth, enough to cause discomfort! and I use an aquarium air valve to eliminate any leakage. never had them fall off, always had to release the valve.
@Niaja
Yes, 4" PVC coupler and cap glued together. 4.5 Inside diameter, 5" depth. Using a brass threaded to barb fitting, automotive grade vacuum hose, tee and air valve from an acquarium. One set has an electrical connection so I can use TENS and pump at the same time. Leak free, pump once and forget it.
Also make a 3" set and a 6" cap that Iuse on my bootie! i also mad a bumch of vacuum related breast bondage devices but that's for another topic, on my kinky bondage forum! lol
