Anyone have specs on o-rings? I have a unit that was purchased in 2016 (old model) and the o-rings on the end of the hose as well as the ones on the unit where the hose connects are disintegrated and the company will not give out that info. Instead they want me to send it back and pay $129 to replace them themselves. I’ve looked around myself but because they are so damaged I’m having trouble finding the perfect match. Thanks
