Upgrade your MKII pump with a 304 stainless steel replacement head. Stainless steel is more durable if you are attaching ball valves. Very cccasionally the threads on the plastic head that comes standard on the MKII can break if you are using hard to close ball valves that apply a lot of torque. Stainless steel is very robust and will not break, is food grade, and well... stainless.

For a more sanitary pump

First drop of polybisphone head makes for a replacement with a stainless steel head. As Sean Connery said when a book hit him on his head, "I only have my shelf to blame."

the magnetic pump without the steel head isn´t as good

Decent pump head replacement
The original head on the MKII is not super for attaching lots of heavy stainless steel. This replacement head upgrades the weakness of the original as others have noted.
In the head I received I noticed that the outlet was not polished or beveled, making for possibly difficult cleaning and sanitizing. The tiny surface scratches on the seal area do not seem to affect the seal.
There was not a replacement seal included with the head but my new pump's seal looked fine. You may need to order a new seal if your pump is older.
Finished Setup, new angle with quick diskos & ball valve.
Rough outlet opening, imperfections on polished surfaces.

A must have when purchasing the pump. The plastic pump head did not hold up well however stainless steel one is a beast

Almost perfect--but still definitely worth every penny
Almost worth 5 stars, but the item came with damage on the surface that mates to the o-ring on the impeller housing. I took a sheet of 320 grit sandpaper placed on my drill press table (nice flat surface) and rubbed the pump head surface down for a minute or so. You could hear the nicks and dings grinding away for the first few seconds then it went smooth. Placed it on the pump and tested it with a fully primed pump and shutting off the output with a ball valve--no leaks! This little pump ROCKS! I have only tested it the pump with a bucket of water, not during a real brew day, but i don't expect any issues (but will report back if some arise).
