As I don;t know where you are I am a little reluctant to speak with absolute certainty. However I am in the North East and have done this all my life. I have never encountered an oil company that does not use this thread. Also on a side note. I have used conventional pipe dope on my threads which the oil will eventually break down. You may want to pick up a can of Gasoila It will not be broken down by the oil and as a result your threads wont weep oil.
This is just one fitting sold alone. The Home Depot does offer speed fill caps and pipe nipples but they would be sold separately.
