Description
Resealing the Joint Side
The stopper seals in two places: shaft to stopper (the gland seal) and stopper to flask (the internal parts). Vacuum loss at the neck, or a joint that no longer seats, calls for this kit in the matching size.
What to Know Before Ordering
- Match the stirrer: K24 and K29 parts are not interchangeable
- Full reseal: fit new gland seals at the same time
- Fit: press into the stopper body, no tools
In the Box
Internal parts kit for one stirrer. Backed by our One-Year Total Care Warranty covering parts, labor, and specification compliance.
