Vacuum pump connector quest

In CF business many ordinary stuff or less ordinary change their name with something a bit more scientific so you can buy it much more expensive and in exact places

So a simple bag for food can change its name in to "Special extra elastic film" and from 10 cents a piece it can be sold 1 euro a piece
All you need to do is try to find compatible things for your workshop

One of these is a connector that will connect your vacuum pump with your bag
Because i thought that 45 euro for the connector plus 30 euro for a simple quick release plug is too high for my budget i searched to find something compatible
Unfortunately  i only found the quick release plug (6 euros ) so instead i made my own vacuum connector and it worked fine , it had some faults though

Air pressure wasnt enough , especially for large pieces or bags and had quite a leakage , the most important thing was that the resin easily blocked the air passages i made

Here it is , the shiny clear film is dried epoxy resin that i had to clean every time i used it

So it was time to bite the bullet and search more for a good vacuum pump connector and i did

I found it in a store that sells air conditioning equipment for 22 euros plus 6 euros for a quick release plug so i can remove it when i want to use the vacuum pump to another bag

Today I was working from 6 o clock in the morning to 20:30 in the afternoon but i was dying to try it out
I made a test ride with a mold to see how much pressure it can handle and the results were pretty good , i wanted to make a piece but i guess it was too late and i must go to work again tomorrow
