Mityvac has improved its line of Fluid Evacuators, Nos. MV7201, MV7400 and MV7300, for better performance and reliability. Changes include:
- Improved lid gasket design to prevent leakage between the lid and reservoir; sealing surface area has been increased for an airtight seal during vacuum and pressure applications.
- Reservoir lid gets self-locking nuts to prevent leaks.
- Overflow shutoff valve threads into the evacuator lid (instead of being glued), to maintain proper valve positioning.
