I cleaned the engine seawater filter. What material they are made these seals? They are on sale? what worries me most is the cost of shipping.
Thanks for any advice.IMG_2476.jpg IMG_2474.jpg IMG_2473.jpg

Gaskets are sometimes rubberized cork and sometimes neoprene rubber.. You can cut gaskets out of sheet material from an automobile parts shop .. very inexpensive..

Any good hardware or automotive supply will have sheet rubber. I got some 6"x6"x1/8" pieces for about two bucks reach at Ace Hardware. If your strainers use O rings, the hardware will have those too.

I'll try with cork, when I tried the gum, but goes out clutching the seat, thanks.:)

It is my opinion the 90 degree elbow should be on the downstream side of the filter, The spectre of a blockage in the elbow leading to overheating is ugly. I had a small fish block my though-hull and cause the temperature alarm to sound. If I had a blockage in a hard elbow I would have been long in finding it. Just FYI for your reinstallation.

You have much reason! Now I have another filter, but I would like to put back this original, when I find the seals parts, put it back listening to your advice.

That's a great strainer and Mainsail has rebuilding instructions on his website for that model I believe. Too bad for me Hunter switched to the cheap plastic strainers for engine and HVAC on the h36....

I switched to a different strainer. In my opinion, if your strainer is old (mine was 1990), and has experienced and "de-zinc-ing", as evidenced by pink if you scrape the top layer off, this strainer will sink your boat. The bolts used to hold down the lid split on the underside which was not visible so you won't know you have a problem until you have a failure. If you have new bolts, maybe not an issue. The potential to have this problem is increased if you tighten the nuts too tight on the lid - which will cause the bolt to split on the underside. The lid popped off my strainer, luckily I was there when it happened and could close my seacock. This Perko strainer is way too expensive (costly parts also) and the new plastic ones (Groco ARG series raw water strainer) withe the bronze heads are excellent and I switched to the model pictured below and at a much better price for the unit and replacement parts. Just my opinion.

Thanks for the advice. I put a more modern filter. The old one is on display on the coffee table ...
