G1/4" watercooling vacuum fill pyrex pump adapter

Adapter for Pyrex vacuum pump which allows you to connect it to standard G¼" PC watercooling fittings. Thanks to this you can fill your loop from drain port sucking in coolant or water from bottom to top, effectively removing all the air and bubbles.

For extended durability, its good to add rubber seal and one extender fitting as part of the adapter.

This model is adapter only, no pump included.

To fit the adapter you need to remove silicone rubber from the pyrex pump, chamfer the outer edge that held the original seal a bit and then simply insert the adapter. For improved vacuum, you can apply CA glue into the connection. Below is a short assembly video clip:
