Eric, What are you using to try and get it out? You may have to cut it out. Sometimes the plastic cannot withstand the pressure needed to break and old screw joint loose. I've had to remove many a broken nipple over the years and the plastic ones are the easiest. You need one of those mini hack saws. You know the kind that have a 6" x 1/4" blade with 2 little pins at each end to hold it into the "bend rod" handle? Like this one; http://www.sears.com/shc/s/p_10153_12605_00977237000P?sid=IDx01192011x000001&kispla=00977237000P&srccode=cii_17588969&cpncode=33-112747568-2
You cut the plastic fitting close to the fitting, take the blade only and cut onto the fitting, perpendicular to the threads, slowly and patiently. You need to stop just as you get to the the threads on the female fitting. Do this twice, the 2nd one about an eighth of a turn away from the first. Then, take a small chisel or screwdriver and knock the smaller part, in between the cuts, in. This should be pretty easy with plastic as it will break much easier that a metal male fitting would. From there you should be able to either squeeze the bigger part or try prying it. It is not too bad a chore but it does take time and patients. Let me know if this makes sense or not and I'll try and clear it up.

I want to replace the hose barb with another one, but can't unscrew it from the thru hull valve. Teflon tape shows on the plastic threads of the barb so I expected it would be an easy job to unscrew it, but so far I can't move it. Tried a heat gun on low heat but didn't help. Any ideas what to try? - obviously I don't want to break the plastic fitting and end up with the threaded portion stuck in the gate valve.
