VeneerSupplies.com Lock-On Connector
This vacuum connector securely attaches to vacuum bag stems and vacuum clamping fittings offered at VeneerSupplies.com. It has a soft O-ring inside which makes a leak-proof connection. It is a nifty little connector that is affordable, durable, and easy to use.
VeneerSupplies.com Flush Mount Bag Stem
The flush-mount bag stem allows you to use the full length of the vacuum bag without worry of project surface imperfections caused by the protrusion of the standard bag stem. These bag stems have a specially designed 2.5" diameter 50 mil flange molded onto the valve body which gets cemented onto your vacuum bag. A sharp-barbed brass insert slides into the valve body and locks into place.
- Mark the location on your vacuum bag where you wish to install the bag stem.
For convenience, we recommend installing the stem 15” out from the bag
opening. The location will not affect the pressure inside the bag.
- In the selected area, cut a 3/8" diameter hole in the vacuum bag using scissors
or a razor knife.
- A small tube of cement is included with your bag stem kit. This cement will
work with both vinyl and polyurethane materials. Be sure to follow the safety
instructions included with the cement and wear appropriate eye, skin, and lung
protection when using this product.
- In a well ventilated area, clean the mating surfaces of the bag stem body and
the vacuum bag with acetone. A synthetic abrasive pad will help maximize the
effectiveness of the cleaner. When completed, the cleaned areas should look dull
- Apply the cement to the bottom of the valve body and to the vacuum bag area
where the bag stem will be attached. Be sure there is full coverage on both
- For vinyl, allow 3 to 4 minutes for the cement to set up. Then apply the valve
body directly over the port hole (step 2). Using adequate pressure, smooth out
the bag stem flange until any air bubbles are removed. A wood roller is helpful
with this process. Allow 1 hour of drying time before using the vacuum bag.
- For polyurethane, immediately set the valve body directly over the port hole after
application of the cement. Gently massage out any air bubbles but try not to
squeeze out too much of the cement. Allow 24 hours of drying time before using
the vacuum bag.
- Insert the brass barbed valve that is included with the bag stem. Proceed
carefully since the edges of the barbs are sharp. Once inserted, the valve core is
not easily removed.
