Homemade Funnel for Stan’s Sealant

Stan's sealant funnel

I cut an empty plastic bottle down, threaded on the Stan’s injector cap, and then snipped the end of the cap to match the outer diameter of the valve stem. I removed the valve core, and used the outside of the stem to cut threads in the inside of the funnel.
Match it up, measure Stan’s Sealant into the funnel part, and you’re done. Easy.
