Replacement o-ring set for X4/X4D probes. Includes two o-rings. The thinner o-ring (size 031) is for the probe body, the thicker (size 130) goes inside the probe cap.
The thicker o-ring on my probe broke when I was changing batteries. Price and shipping was reasonable and arrived in a few days, saved me having to try and find the correct ones otherwise. In hindsight I should have ordered a second set for spares.
Same as Original Parts
Worked like a charm. Looked locally for the right size O-rings and failed.
Hopefully new rings will prevent water leaking into battery compartment
