It seems that my local auto parts has two sizes for me to consider, the one that slips off of the rigid plastic piping all to easy and the second, that requires a soaking in scalding hot water before fitting, or the use of a small phillips head screw driver to stretch and wallow it out before using all of my strength to drive it on.
