We had our first (and hopefully last) flat on our Clarity PHEV last month. My wife had the car and used the tire repair kit (pump and sealant) to temporarily repair the damaged tire. The dealer told me that I needed to order an entirely new kit even though it appeared to me that just the sealant cartridge could be replaced. After some research I ordered the Slime 10179 refill kit from Amazon. https://www.amazon.com/gp/aw/d/B073...F8&qid=1521277634&sr=1&pi=AC_SX236_SY340_QL65 While looking almost identical, the knob and valve are slightly different shape. Easy fix was just to swap those parts with the ones on the used component and now it’s good as new. Highly recommend this solution. I actually think the OEM is a Honda branded Slime unit. Chemistry and test of parts seem identical.
