Raypak heater drain pet cock

Postby jnolee » Fri 11 May, 2007 15:54

I cannot thread the drain petcock in my raypak heater. It appears that the threads are rusted out. Is there an expandable rubber plug that I can replace it with?

I had the same problem with my Teledyne laars heater. The problem is these manifolds are cast iron which rust pretty easy. What you need to do is drill out where the petcock was 3/8ths drill bit then put a 1/4 3/8ths sleve in. Use pipe dope in the threads this will prevent the threads from rusting.
