Product Description

This is a barbed brass insert that slides into the stem portion of our flush-mount bag flange found on our vinyl and polyurethane vacuum bags. Works with our lock on connector.

Important Note
We recently changed the lock-on connector that is included with our vacuum press kits. Please click here for more information. Be sure to select the version of this stem insert that matches the lock-on connector you have. Alternatively you can order an updated lock-on connector.


Made in the USA!

How do I remove the old brass stem insert from from my bag?
Hold the flange flat with the nipple between your third and fourth fingers. Then grab the end of the brass fitting with pliers and twist while gently pulling it out of the flange.

Product Reviews

  1. Great Product and Great Service

    Review by Bill Lindenfelser

    I have bought both these inserts before as well as the EVS system kit. My projects have ranged from 30 in long curved panels in Douglas fir to a large table top (60in x 60in, using a large, folded sheet of vinyl for the bag). They've all come out great. I'm pretty handy, but when it comes to the possibility of destroying a large substrate and costly veneer, I like to have some assurance that I'm on the right path. Joe has been great at providing that.

  2. Review from Eureka, CA

    Review by Gabe Douge

    This Schrader x barb is a fantastic fitting for the vacuum bag stem assembly. Leak free coupling when used with the lock-on vacuum connector. Super easy to use and extremely affordable.
