Just make sure you use the red automotive RTV because it is rated for higher temps.  A PC gets up there in temp and I have had other RTVs fail.

Not correct.  This is the biggest mistake guys make when they use silicone. RTV silicone is designed for much hotter temps than found in a pressure cooker and it doesn't cure properly, usually peeling off later.

Simply use regular silicone, not the high temp RTV. Clear silicone is good for up to 300F, which is well below a pressure cooker temp. You could also put micropore tape over the inoculation holes and simply cover the wound with another piece of micropore tape after injecting.

All silicone is rtv if it smells like vinegar. The stuff marketed as rtv is usually automotive application. Its silicone with additives to make it take >300F or be more brittle (gasket material)

Kitchen and bath 100% silicone (avoid acrylic) is going to dry more flexible so the injection port sticks to lids longer both metal and Plastic. And can take more needle pokes before needing replacement.

Most guys who have used RTV have had it peel off.  Use regular clear silicone.  It's rated to higher than a pressure cooker goes and remains flexible and attached to the lid.

Actually, people really need to get away from syringes once they move on from the brf tek.  Using them is sort of like putting training wheels on a Harley.
