Hi I've lost the smaller bolt in my Sendure heat echanger, the bolt that drains the freshwater. Does anyone know the dimensions of that bolt? Diameter, length etc? It´s hard to reach the hole with proper measuretools and it would save a great deal of job if anyone knew!? |

Is it a bolt or actually a pipe plug? |

It's a brass bolt (I think that´s the right word at least) with screwthreads on, about 1/3 inch diameter as far as I´ve been able to measure without taking the hole exchanger off! |

Try a brass hex head or square head 1/8" NPT pipe plug. Drain plugs are typicaly tapered pipe thread. You can get them at most hardware stores. I suggest you get the hex head and get a 1/4" one as well in case the 1/8" is too small.
I use NEVA SIEZE on the threads or any of of a number of anti sieze products to make the plug easy to remove at a later date. Keep a tube of it on the boat and use it on screw threads to keep corrosion from making it difficult to impossible to remove at a later date. It comes in tubes like tooth paste or in cans and larger containers just a little dab is all it takes. It gets on everything if you use excess amounts so have a paper towel or rag handy. Its just messy but well worth avoiding the agony of trying to get a machine screw out or a nut off a rusty thread. It wont help you get the plug out if you have not put it on when you put the plug in.
When you first try to screw the plug in don't force the threads it should screw in a couple of turns until it is finger tight. Once you are confident that you have the right plug then you can add the anti sieze and put the plug in until finger tight then tighten it up with a small wrench. Don't over tighten just firm so it won't leak and fall out. DON'T USE A STEEL PLUG!!! |
