Gasket size for cover of intake water cover by sea cock
« on: August 10, 2017, 06:35:09 PM »

Anyone know the specs on this? Hoping to pick an extra one up when I try to fix this tomorrow. Seems simple enough, but if anyone has unsure or tips that would be great!

That is your seawater strainer and it uses an O-ring. Unless you have exact manufacturer and model number for your strainer, IMO too risky to order online. I suggest you take it and the seawater strainer cap to ACE hardware or a marine hardware store and match its O-ring.

Noah : The raw water intake is a HYPRO Series 3350 inline strainer made by the Hypro Corp, New Brighton Mn.  (612) 633-9300
It should be the 3/4" model 3350-0034 / 44 with a gasket # 1700-0044 / 45. 

Hope this helps    :D

Noah : BTW it's not an "O" ring per-say it's a circular square gasket.

Ok Ron. Good catch. My bad. Not the brand strainer I use so, just looked like an O-ring in the pic.

Looked like a std o-ring to me too from the photo.

Although technically, it's probably called a "square-cut ring", in my circles  (bad pun :D ) we still call them o-rings, just "square-cross section ones or "square-rings." There are other cross-sections available too, such as "quad".  See:

They are usually fairly interchangeable in non-critical applications.
