Hello Daniel. The Armco Tank O-ring PF15-2127 O-184 fits the Pentair/Pac Fab/ Nautilus Stainless NS Series DE Filter. The American Products Filter model DC-36 did not cross-reference to this Tank O-ring.

Will this o-ring fit my Nautilus (Pac-Fab) model # NSS-48? My DE canister is stainless steel and is at least 25 years old. If this is not the correct o-ring, is one available?

I have a stainless Steel D. E. filter (Model# NS24). My hired technician states that he can't find this o-ring because its discontinued and not available. Is this o-ring available for purchase?

My old ring is triangle profile not round. I have a 15+ year old stainless de filter tank 48sq ft and the tank inside dimension is 18". I have purchased the 152127 and it is at least a half inch to big. Do you sell the 18" o-ring with the triangle profile?

Unfortunately, no, they are no longer available. The Tank O-ring 18" Generic - PF15-2127 O-184 and OEM Nautilus Stainless Filter Tank O-Ring - 152127 are only for (18" O-ring) for Nautilus Tank O-Ring *AFTER 2001.

I am concerned to order this. Seems that there are generic 18" O-rings claiming to be replacements for 152127, but when installed are too big. Just bought one from local pool store and it too was too large. I see on AMZ that other people are having the same issue, while some are not. Seems it is hit or miss whether the o-ring is actually 18" or 19" even if it has the 152127 or O-184 part number. How can I be assured this generic is indeed 18" and thus not too big?

Is this o-ring a wedge type ? My original is wider on one side and more narrow in the other....does that make sense??

First I drained about half of the water from the tank. There is no need to drain it completely if you are only replacing the tank O-ring. I removed the band and carefully separated the two halves of the filter housing with a putty knife. If more water comes out at the seam just drain a little more until you can lift off the upper half of the tank. My old O-ring was hard and shaped like a wedge which was the reason it was leaking. I coated the new O-ring all around with silicone pool sealant. Do not skip this step. Next, I carefully placed the O-ring on the lower half of the filter housing. It looked slightly over-sized, and kept slipping into the tank as I lowered the top half down on it. It would have been easier with a helper, so keep that in mind. I kept tucking and shifting it until it was in place, even though one spot bulged out slightly. The band went around it easily and actually corrected the bulging area. I tightened the band to leave a gap of 1/4" between the bolt keepers. I decided not to strain the band any more than was necessary for a good seal. The new O-ring is going to be thicker than the old one after years of compression, so do not expect the band to tighten down as tight as before. I primed and started my pump and it did not leak one drop! Thank you Inyo Pools for a high quality replacement O-ring.
