These new PTFE KF(NW) Adapter pieces (inner) let you convert a glass joint into a KF connection.
Beaker & Wrench help you take an open joint and turn it into a vacuum connection. For the first time, you can now pull vacuum from this area/joint.
Please remember to use a vacuum clamp and centering ring to ensure a tight seal!
Note: When using these fittings in conjunction with a vacuum monitor, the vacuum probe should never lie upside down. A vacuum probe should always be in the upright position, and it may require a 90° adapter to do so.
