If you use your vacuum press for vacuum clamping, this fitting will allow you to directly attach the lock-on vacuum connector to the vacuum clamping jig. The 1/8" NPT version of this fitting is the one that is used in the JoeWoodworker vacuum frame press article.
Use the option above to select the correct thread size for your vacuum jig. Both sizes have a Schrader thread on one side that is designed to attach to our Lock-on Connector.
Thread Size: 1/8" NPT or 1/4" NPT
Connector Size: Schrader
