This is the one! The only connector that works perfectly every time for vacuum pressure!

This solid brass connector locks on to the valve stem with a strong spring-loaded clip and features a soft cast O-ring which makes a leak-proof connection to the vacuum bag or vacuum jig. This superbly machined connector has a 1/4" NPT-female thread. We are now shipping all lock-on connectors with a special large bore to allow maximum vacuum flow. To use this connector with your vacuum press system, you will need a brass barbed fitting to match the inside diameter of your tubing.

This connector attaches to any "schrader" style valve or connector. It works with our valve stem for vacuum bags and is also compatible with our clamping jig fittings. For more information, see the links below.
