This is a basic question but i'm going in circles looking online for the answer to this.. My new Intex Sand Filter tells me to coat all threads with Petroleum Jelly.. I've read elsewhere not to use that especially near rubber rings.. I picked up a tube of Silicone Lubricant meant for pool equipment today.. but in further looking I saw someone recommend a Teflon based lube which is silicone free..
My question is, what is the purpose of using lube on the threads? to make it easier to get off later? and which should I use on my threads and rings during new pump install? i've seen a pool guy use a silicone spray on an O-ring but as you can tell i'm highly confused and just want what is best for this new pump.. do I coat just where the ring is or do up all the threads? and with what product?
