Reusable, Leak-Free Vacuum Connection
This Vacuum Connector is the most economical choice for a reusable, leak-free vacuum port in a basic vacuum bagging or resin infusion installation.
Installation is simple: insert base within vacuum bag, then pull threaded opening through a small hole made in the film; slide on O-ring, followed by the nut.
Air can be drawn directly from the vacuum bag by attaching 1⁄2" Vacuum Tubing (#893), secured with our continuous band Hose Clamps (#789).
Well worth the money for such a specialized item, but a bit of elbow grease makes them even better.
Easy to deal with, inexpensive, and easy to remove dried epoxy if needed. I would advise deburring around the edges so it can't hurt your bagging material.
The Vacuum Connector is sold by the unit (#891-A) and by the dozen (#891-B).
