Flo Company makes a very good quality and reasonably priced expansion type fitting which is really designed for repairs on sch. 40 pipes but works fantastic for a situation like yours.
Some others also offer this but I'd make sure it was made in the U.S.
They operate with two o-rings.
Getting it by the inspectors in your area would be the hardest part.
If you'd like a picture just e-mail me with a fax number and I'll fax you one.
Good luck with your log home. Doing plumbing on them can be a bear because of the outer walls, etc etc.
