The picture may be different from the actual brand of valve, as my supplier changes manufacturers without notice

This is a new 10# OPD valve.

It has the 3.6" dip tube length

If you are not sure what size you need, look at the collar of your propane cylinder and look for the letters

DT

After those letters you will find numbers most commonly 3.5, 3.6, or 3.7.

If it is one of those, this valve will work for you, if not you will need another size valve
