  • Hi John, what pump do you use and what are the pipe sizes? How many degrees dud you cut to be able to insert the whole pipe?

  • GTK. I am about to redo my vacuum press.
    How durable is the film in comparison to other bag makers?

  • Is off-the-shelf polyethylene vapour barrier plastic no good for this?

    I'm not deaf, I'm just not listening.
  • The composite vacuum bag material is designed to be flexible and very durable for vacuum autoclave composites. I've been using this material for only a year and have been surprised how durable it has been. I used some cheaper vinyl bags in the past and they were junk in comparison. You might be able to bag some flat pieces with vapor barrier material but I think it's better to be able to see through the bag.

    I've also been using breather fabric and platens so I might not be stressing the bags as much as others.
    The pricing is right compared to spending $100 for smaller bags.

    Ani the pipe is 1/2 and 3/4 inch. I guess at the opening then cut the 3/4 inch then scraped and sanded the edges for to fit over the 1/2 inch pipe plus the bag.

  • I'm using a commercial vacuum pump because I got it cheap from my work. Amazon has some highly rated ones for $100
