Purchased Jack from Polarstar, just needed some parts. Two thumbs up for tech help. Fast shipping!

Can't live without these.

About every 16 months I end up replacing 1 or all the O-Rings on my Jack and F2 and it is normally at the beginning or half way through the winter months. These work as expected.
