Flexible Pumping / Feedthrough Connection Ports
The TVO-5 ovens offer two different vacuum oven connection points. The standard connection is a 3/8″ diameter barb located at the rear of the oven. It is connected to the vacuum valve on the front control panel. For even faster evaporation, purging or drying consider upgrading to the MAXEVAP connection kit. The MAXEVAP connection kit secures to the oven’s rear 1″ diameter KF-25 port located on the back center of the chamber.

The Installation connection never reduces flow by continuing with 1” diameter vacuum rated clear lines, a 1” diameter KF-25 side mounted vacuum valve, and KF-25 fittings and hardware. This KF-25 port can also be used to run temperature feed-throughs or monitoring sensors inside the vacuum chamber during processing.

Ergonomically Designed, Easy Quarter-Turn Valves
For anyone that has struggled with consistently turning the small, round, low-quality vacuum/vent valves, relief is in sight. You will love our large, quarter-turn vacuum/vent valves. Your wrists will thank you!
