Response to I have a Spring barrel nut assembly on my Pentair FNSP 48 filter. My unit is about 16 years old. The spring itself has 8 coils. All the new assemblies I am looking at have no more than 4-5 coils. I am afraid that if I replace the old with new, that it may not tighten down enough to not allow leaks. Can you offer some help?
