internal pipe wrench

[jimwrench]

 Acquired this set of internal pipe wrenchs recently. Had a single expandable internal nipple remover which was too large for a recent valve removal recently so when I saw this set of four I had to own them. Very useful in removing nipple or valve where od is not accessible. Probably not much in demand since rigid pipe has been replaced with plastic or tubing, but I have a set if you need to borrow them.
