SpaMon345 Posted June 20, 2016 Report Share Posted June 20, 2016 Hello. I have a couple of leaks at the jets on my 2004 Leisure Bay spa. I am trying to find the size of the hex wrench (aka alan wrench) that would fit the center of my spa jets so that I can tighten it against the jet body. I'm guessing it could be 7/16in or perhaps 1/2in or similar. I've done numerous google searches but since Leisure Bay spas seem to have been discontinued, I am finding it difficult to find this information. Also, what is the recommended tighten torque? I read in one place someone torquing it to 10ft lbs but I am not sure if that is a good rule -of-thumb or not. Thanks! Quote Link to comment Share on other sites More sharing options...
SpaMon345 Posted June 23, 2016 Author Report Share Posted June 23, 2016 Well, by trial and error so far I have discovered it is bigger than 10mm and smaller than 12mm. That means it almost has got to be 7/16. Quote Link to comment Share on other sites More sharing options...
Cctau Posted March 18, 2017 Report Share Posted March 18, 2017 Yes. It is an 11mm or 7/16. And it's the one that is left out of every set and usually cannot be purchased separately. So go to the hardware store and get a 1/4 inch bolt. The head will fit perfectly. Add two nuts and you have a wrench! Quote Link to comment Share on other sites More sharing options...
Cusser Posted March 21, 2017 Report Share Posted March 21, 2017 If you search for "allen" wrench instead of "alan", that would make your life easier. Quote Link to comment Share on other sites More sharing options...
