Today's frustration is hatch O ring size. 
I have ordered and received an AS568-743 Buna-N Oring 70 duro Shore A 
23.940" ID X .275" from Webster Engineering Corp per K350 Plans which do 
not 
state size of O ring just part number 
the plans call for a 23.625 ID ring groove .215 deep 
Do these rings get stretched that much?
