    Default Pontoon drain fittings

    I'd like to install drain fittings on my logs. I have someone who has a portable welder (it's a big PIA to haul my boat through city streets), but where can I find the fittings (both male & female)? I'm thinking I should use a different metal for the plug, such as brass. Any ideas?

    They have bigger, these or 1/2 npt is what I've seen used.

    I would use a disimilar plug too, these take NPT pipe plugs that you can get at any hardware store, I would use brass or stainless.

    Thanks, I had no idea where to find such fittings. I figure 3/8" should be sufficient. I don't want to use a ferrous bull plug (even coated) to ensure it doesn't corrode. I was hesitant to use AL as dissimilar metals tend to "become one" with each other, but I figure the threads will be protected by teflon tape so that shouldn't be a problem.

    I appreciate your help Moser, thank you again.

    You're welcome, Sir.

    Sometimes it's just a matter of knowing what they call the thing. Where I worked we made a stainless and regular steel "half coupling" that looked just like that, and was welded in to provide a drain in tanks, pipes, other applications in oil, gas and chemical industries. If you search for an aluminum half coupling you'll get nothing, go figure.
