I need to order a weld on bung for my oil pan. It's a used Peak Boost kit. Is it a standard thing or are there alot of different sizes people use?

 

Standard around here is -10AN

 

If peakboost provides the oil lines then just give them a call and ask.....

The -10AN which is equivalent to a 5/8 npt fitting, BUT the AN fittings are flared, so make sure you get the right type of fitting as well. Whe Joe says is pretty common. Some people will even use a -8AN or 1/2" npt fitting. As for what the kit has.......call and ask. I have swagelok ss hardline with compression fittings so it's a bit different.........man I love workin @ a power plant.

 

2 ways, weld a -10 bung to the pan assuming thats the a-n size in the kit or do a 1/2 pipe thread bung and get a -10 or -12 depending on the size of the a-n / 1/2npt nipple and do it that way.
