Old Style Propane Lines

OK, heres a question for u propane guys. I have an older trailer with the old style inside reverse thread tank fittings that u have to put on with a wrench. I had 1 valve replaced last year, cause it was leaking, when I tried to use the heater over the winter the other valve started leaking and it is still leaking now, I just turned it on to check. I looked inside the valve, it appears to be ok, but just wont seal right, and yes it is an opd. Should I replace the lines with the newer style plastic handles, I just looked at my bbq, they seem to seat differently, so I'm thinking newer is better right? what do u guys think, and where would I get them, any sources?

    Where to get them.. I like to deal with propane wholesale places but not all have them. A good fireplace and BBQ store may have what you need too.. And if they do not, they will know who does.
  • Yes The new style type 1 connection will allow you to connect with out a wrench.
    All 20-40 pound "trailer" tanks now require an OPD Valve and 99% of those are the type 1 connection (Acme threads on the outside and POL female inside). Your older POL maybe worn enough that it will not seal against the QCC seat so just upgrade. Get the green OPD pigtails if you can as they are higher flow.
  • I'd replace the old lines.
    You can get 'em at Camping World, most propane dealers or even Ebay!
