This is a type 304 stainless Keg Land pump head to fit the 25 Watt Mark II wort pump. It features ½" BSP male inlet and outlets to fit ½" female NPT and BSP fittings. It does not include an impeller, as the standard MarkII impeller is used with this head.

Q: I ordered this replacement from another web site and it didn't fit my pump, it leaked through the screws and the sides ... do i need to replace the screws and get some kind of fitting accesory? I returned it then and now the original plastic head broke.
A: It sounds like they sold you the wrong head. Our Stainless Heads fit perfectly. Keep in mind there are no name clones of the Mark II Wort Pump out there, and our head only fits a pump with the Keg King brand on the label.

Q: What are the dimensions of the SS Mark II replacement head and what is the diameter from screw hole to screw hole?
A: It is 2 7/16" from hole to hole. Keep in mind this head does not fit the Chugger or March pump.

A more solid pump head
This SS pump head it the way to go. I wasn't comfortable with the durability of the plastic one that comes with the pump. I've attached a ball valve to the SS Head with no concerns of breaking.
Good but...
Great pump, good SS head, but the unit I received had noteworthy damage to both of the threads, making it very difficult to get fittings on. Required straightening/filing of threads. That's not right. If you buy this check your threads immediately for damage.
steel head replacment
I broke of the original plastic tightening down fixing a leak during my brew day, big problem and a bad brew day. Ordered and replaced with the stainless metal head, 5 minutes and no leaks, good to go. Great service and quick shipping, thanks!
Great product and easy replacement
I needed to replace my pump’s head because the original plastic one broke, I ordered this and was delivered in three working days (super fast) and the replacing process took me at the most 5min. Great product and service, thx! Cheers!
Good choice
This SS pump head is a must and much stronger. The plastic head that comes with the pump is rather delicate and easy to break at the pipe threads.
