hello, the instructions for my Perfect Flight altimeter say it’s a good idea to seal off the bulkheads, with an o-ring or silicone, from the ebay tube to keep the ejection charge gasses from reaching the altimeter inside the ebay. Is this a necessary procedure? I did put silicone into the hole that my wires pass through in the bulkheads to keep gasses out of there. Thanks for any advice you have.
