Davey SpaQuip Semi-universal filter air bleed kit comes with two most common thread types. Used in Davey Crystal Clear, Davey Easy Clear, Monarch, Spa-Quip and other filters.

These have been coloured blue, black, yellow over the years. Fits the majority 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 coarse 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.

• Fine Thread: 1/4" BSP which measures ~13mm diameter on the thread
• Coarse Thread: ~12.5mm diameter on the thread
