Tax included Shipping calculated at checkout.


Davey SpaQuip Semi-universal filter air bleed kit comes with two most common thread types. These have been coloured blue, black, yellow over the years. Fits 90% of cartridge & other filters over the years. This product comprises 2 air bleed valves and one o-ring. The two airbleed valves have different threads. One has a course thread. The other a fine thread. 

Manufacturers used both thread sizes on the same filters which created confusion resulting in this part being offered as a universal kit.

  • Course Thread: ~12.5mm diameter on the thread
