Installing jets

[stuart]

  Stuart is right,  the seal is made on the front side of the jet housing,  the nut on the back is to tighten the seal on the front.  You might see silicone on the back side of a shell but it is from the threads and excess from the front...  
   Stuart, why the Arctic blast?     Arctic had nothing to do with the topic, and I was asking a question about how someone thinks jets seal from the backside!!!

Sorry did I forget to include the   faces to make a joke of it?

  Is that what you were trying to do?   Because the     do make it really funny
