Rated 1 out of 5 by from Made my situation worse Bought the Marineland 360 canister for my dad at a good price and had issues with air getting in, presumably through the o-ring. Tried silicon-based lubricant, still would not seal. So I ordered this kit and paid a bunch of money for shipping. Went to put it on the filter, and it made it worse. Water started shooting out. We ended up throwing everything out and buying a Fluval, which has ran perfectly. Will never be buying this brand again.

Rated 5 out of 5 by from Repalcemet gaskets did the job Purchased the gasket kit for a Marineland C-360 filter that had started leaking. The gaskets were easy to install and repaired the filter so that I did not have to buy a new one. Well worth the purchase and time to install.

Rated 5 out of 5 by from Customer service It took me a few phone calls to have my problem answered and fixed. Once I did, it was smooth sailing all the way. I was treated with respect and my problem was taken care of in a matter of minutes. I am very happy with my results and the representative that I spoke with was absolutely amazing. Marineland products that I have are great and long lasting.

Rated 4 out of 5 by from Great product I bought a replacement seal set, about $7 my surprise, $35 with shipping. It did arrive quick, but I really think Express (expensive) shipping should be an option.

Rated 3 out of 5 by from The part fixed my issues My filter was leaking anytime I shut it down and would leak a little wile it ran. So I red up on my problem and that my gasket was bad so found this on the site cheep but my issue is that the shipping was more then the part so if you can find the part in the store do it but I could not find one anyware around me.

Rated 2 out of 5 by from Why isn't the rubber gasket in the instructions?! Just bought this filter, followed instructions to a T, only to plug it in and literally have it flood my entire den!! Come to find out, there's a rubber seal that's supposed to be included that goes around the motor head. Wasn't in the box, and didn't say it ANYWHERE in the instructions.

I ordered gaskets for a C-360 filter and the valve block gaskets are two large to reinstall the valve block. Can you suggest a gasket part number that will work on my filter

Asked by: PaulPaul
Sounds like you may have ordered the wrong kit. You either have a smaller filter or you have the Magniflow version, not the C-360. Please call our Care Team at 1-800-322-1266 for help. BREX

Do the o-rings for the magniflow 360 go on the top of the valve block or the bottom,which one is it?

Asked by: Chris poodleson
They would go on the ports that are found on the underside of the valve block. BREX

does the kit include the primer button gasket? if not how do i purchase it?

Asked by: JerryA
No, and unfortunately, that is not available separately as the primer button should never be removed. If you are within the 3 year warranty period of time, please call 1-800-322-1266. BREX

What are the small gaskets with the 360? I put in the big one and I don't see any leaks. There was no mention in the manual of these 2 small gaskets. 

Asked by: RS63
Thanks for asking! The small gaskets are extras for the two on the valve block.

I have a C360 and when I disconnect the valve block (and close off the valve all the way) water still runs through the inlet hose (more slowly than when the valve is open, but fast enough that I have to put the valve block in a bucket while I'm servicing 

Asked by: SugarMonkey
Sounds like either the valve block is partially clogged, and in need of cleaning so it will close correctly or has some old o rings, and needs replacing. Try cleaning the ports, all four of them, out with a soft wire brush and water. Run a strong jet of water through them. Hold it upside down, and observe the openings while you lock it off. We do sell it separately. BREX

There is a large grey colored rubber gasket in the original C-360 box, I'm assuming it's supposed to be covered with Silicon grease and placed around the motor head. But there is already a black gasket in the only spot I can see to install it...

Asked by: Sassonic
Thank you for asking, Sassonic. You are right about placement. The second gasket is a spare for you.

Does this kit come with instructions?

Asked by: AnthonyD75
Not that I know comes with the large motorhead o ring, the tray gaskets, and two o rings for the underside of the valve block. You essentially pull off the old ones, and gently pull the new ones into place. BREX
