5 x Mac Allister Pressure Washer Hose to Gun Quick Detach o ring seals.

This is the o ring for the connection between the hose and the handle (and on some models the hose and the machine). 

There are 2 different versions of this connection. This listing is for the one that is around 8mm external diameter (Ref 49.5).

The other version is around 10.5mm external diameter (Ref: 60.5) and can be found here.

If you don't know which version you have we do a pack including 3 of each size, which can be found here.
