I have to put on two new split nuts on either end of the spa pack. Should A guy use some type of lubricant on the piping threads to make it go on easier when turning it? Also, how tight do they have to be, I watched a video and a guy used a specific wrench to tighten them, which I do not have. I was going to attempt it by hand.
When I took it apart, I didn't know they went on by turning, so I just unscrewed the screws and split the nut apart.
