There is a special shark bite coupling now that is made to hook onto Poly B now, when you look at it one side has the plastic parts are grey colored. Regular shark bites will work but they are not approved as previously stated.
As to gas lines safety for you and your family is rule #1 might be best to let a professional deal with it, he has liability insurance and trained to properly deal with it.

When a plumber visited my home, recently, and saw that I had used Sharkbit fitting to connect my PB plumbing to my laudry single lever shutoff valve, he made the comment,"Oh, we don't like them." I asked him why he said that. He said, "Because, if everyone used them, we might be out of business."
VERY EASY to install! Works great and I don't anticipate any problems. Since I missed the class action suit before it closed, I have one eye open to it being re-opened. In the mean time, my mind is at ease, knowing that, should the need arrise, I may not even need the services of someone who charges so much to replace a fitting or a valve! Three cheers for Sharkbite! I hope the inventor is a millionaire.
