The Cheap and Easy Way to Finish Vacuum Lines

March 13, 2017 36 Comments




I’ve been doing composites for a few years now and I always see people using those through the bag type vacuum connectors like this connector from Fibre Glast. I see them in the mid $20 to close to $40 range depending on the supplier and the fittings it comes with. Believe it or not, I’ve actually never used one in the few years I’ve been doing composites. When I got started it was an expense I didn’t want to pay. Now I’m just so used to doing it my way, I just never got one (or a few if you have a few parts going at once). They seem to work nice so I have nothing against them, just never adapted to using them. Below is a picture of the cheap and easy ways the I fill, or cover the ends of vacuum or infusion lines. On the left is a semi rigid vacuum line with some bleeder taped onto the end. The bleeder helps distribute the vacuum across the part and it keeps the bag from getting sucked into the end of the line. If you utilize this type of vacuum line with Stretchlon 200, without the end of the line covered or filled, there is a very high likely hood of the vacuum actually popping a hole in the bag as it get sucked into the vacuum line. The second is a more flexible, softer line that I use mostly for infusions. I will get a small scrap of flow net, roll it up, and stuff it into the end of the line. This keeps the vacuum pressure from sucking down and closing off the end of the line. I’ll also use this technique with the harder white lines on the vacuum side of an infusion setup. It would be a good idea to get some cheap spring loaded clamps to keep the vacuum lines against the mold flange as they can pull themselves off sometimes. You can mix and match the tubes with either the bleeder or net as you see fit for your purpose.

There you have it. Two cheap ways to finish vacuum lines when you are getting up and going. Try it out and let me know what you think, or let me know if I should pick up a few of those through bag connectors.

  2. Hey this is kind of of off topic but I was wanting to know if blogs use WYSIWYG editors or if you have to manually code with HTML. I’m starting a blog soon but have no coding knowledge so I wanted to get guidance from someone with experience. Any help would be enormously appreciated!

  7. I like using PEHD through bag connectors like these ones: https://www.google.fr/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&uact=8&ved=0ahUKEwjXzqqLiPXWAhUHPxQKHRNyCoAQjRwIBw&url=https%3A%2F%2Fcompositeenvisions.com%2Fairtech-vac-ric-resin-infusion-connector-1-2-hole-and-groove-1602.html&psig=AOvVaw3_K5tt60qPFzO0eg8o0smE&ust=1508240529974455

    They are great through bag connectors both for the injection line and vacuum port. Being PEHD and monoblock they are much easier to use and reuse than metal through bag fittings.
    Though the metal one are the way to go for prepregs as the curing temperature can play havoc on the tubes and gum tape (plus if you do your prepreg right you shouldn’t suck any resin out through the vent).

    so people could connect with it better. Youve got an awful lot of text for only having 1 or 2 pictures.
    Maybe you could space it out better?

  23. I have been browsing online more than 2 hours today,
    yet I never found any interesting article like yours.
    It’s pretty worth enough for me. In my view, if all web owners
    and bloggers made good content as you did, the net will be a lot more useful
    than ever before.

I think that you simply can do with a few to power the message home a little bit, but instead of that, that is magnificent blog. A fantastic read. I will definitely be back.|

  29. Hey there would you mind stating which blog platform you’re using? I’m planning to start my own blog in the near future but I’m having a hard time deciding between BlogEngine/Wordpress/B2evolution and Drupal. The reason I ask is because your design seems different then most blogs and I’m looking for something unique. P.S Apologies for getting off-topic but I had to ask!|

    IE still is the market leader and a huge component of other people will leave out
    your great writing because of this problem.
