    O ring tips

    They are different size. Get them in the right place. Gently lubricate so the don’t distort. Use visibility through the plastic to confirm a good seal. Don’t tighten too much or you will distort them into not sealing. Once it leaks the battery pack will eventually corrode and then you will need one of those.

    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.

    Worked like a charm. Looked locally for the right size O-rings and failed.

    Hopefully new rings will prevent water leaking into battery compartment
