Can anyone tell me the O-ring sizes (not the manufacturer part numbers) for a Nautilus (Pac-Fab) NS-72 or NSP-72 DE Filter and Back-Wash Valve? I have either the NS-72 or NSP-72. The nameplate decal is faded so much I cannot tell if its an NS-72 or NSP-72. I'm curious what the difference is between an NS-72 and a NSP-72 DE filter if anyone knows?
The O-rings I'd like to replace are the following:
1/. Tank O-ring. This is the large (roughly 18") O-ring that seals the tank.
2/. Manifold O-ring. This seals the manifold to the stem pipe inside the filter.
3/. Back-Wash Valve Cap O-ring. This seals the back-wash valve cap in the main housing. The cap is secured with 2 screws. I believe this is the old style (original) back-wash valve.
4/. Back-Wash Valve Shaft O-ring. This seals between the back-wash valve shaft and the cap. The shaft is 3/8" in dia. I think.
Thanks!
