If your Sight Glass is leaking where the glass tube enters the Base Seat, here are some quick and easy troubleshooting tips to get you back up and running quickly!
Troubleshooting Tips
- Is the glass tube straight and inserted fully into the base seat? It should be all the way in and straight.
- Also, the base seat contains two o-rings which should each be seated within a groove inside the base seat. Look inside the glass/base seat to make sure those o-rings are seated correctly. Did one of them get pinched or shifted or something like that? If so, remove the glass and reinsert the glass correctly so that the o-rings are sitting properly.
- Check the placement of your measurement sticker. It should never extend down into the base seat. If your particular evaporator requires the sticker to be so low on the tube that part of the sticker could extend into the base seat, then that sticker could be disrupting the seal of the o-rings. If this is the case for you, cut the sticker so that it does not extend into the base seat.
- Try flipping the glass tube around so that the opposite end is inserted into the Base Seat. It is possible that one end may fit better than the other. Micro-variances in circumference are unavoidable due to the way the tubes are crafted.
- If all else fails, try a new set of o-rings. NOTE: The o-ring replacement packs for the Draw-Off Sight Glasses and Float Box Sight Glasses include two different sizes of rings so you can mix and match to find the absolute best fit. Most commonly, using one thin o-ring and one thick o-ring offers the best fit.
