Chukkinsod Posted December 4, 2015 Report Share Posted December 4, 2015 I learned the hard way that there are two different sized ends to Pingle petcock. The hole in my drag tank looks like 3/8 but the Pingle I got has 1/4 threaded. I was just going to insert a reducer so it will thread into my tank. Anyone know what type fitting is not corrosive with Alchy? Not sure if it will corrode brass. Quote Link to comment Share on other sites More sharing options...
Chukkinsod Posted December 5, 2015 Author Report Share Posted December 5, 2015 Got it to work with reducer but one side of pingle leaking when valve closed in off position....looks like its off to them for a rebuild. Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted December 6, 2015 Report Share Posted December 6, 2015 The brass barbs pull out fairly easy , there's an o ring behind there might be able to find one local and fix . Quote Link to comment Share on other sites More sharing options...
Chukkinsod Posted December 7, 2015 Author Report Share Posted December 7, 2015 I was wondering how it came apart ..was not sure if the center pulled out when lockwasher was removed. So basically pull the barb out replace washer press barb back in. Seals on one side...leaks slightly on other assumed this was basically a ball valve.

Chukkinsod Posted December 8, 2015 Author Report Share Posted December 8, 2015 Thanks for the help sleeper. Is the brass an NPT fitting (twist off) or is it just a barb (pull out) I am going to fix it or break it this weekend! If I find o rings local ...ill post where and what size/part number.

Chukkinsod Posted December 10, 2015 Author Report Share Posted December 10, 2015 Pulled it apart and found an oring twisted in the 90 degree barb fitting. Surprised that the 90 was just pressed in no threads so pulled apart replaced oring pressed back in with vise...good to go. Just a viton brow oring in there on each side sealing the ball valve. Thanks for the help! Quote Link to comment Share on other sites More sharing options...
