    4" San Juan engineering heat exchanger end cap

    Looking for a replacement for one of mine that is cracked or a good source for a replacement.
    I stayed up all night to see where the sun went. Then it dawned on me....

    They're very expensive when compared to Seakamp Engineering in Bellingham. They can provide exact duplicates of San Juan's products for much less money.

    This is what I bought for my boat they are $$$. Crusader 22094 Rubber Cover 4" CRU22094

    I bought a Quality SS spring loaded clamp. If this is the correct cap let me know and I will look up the clamp I used. The cap is laying the floor bottom left pic.

    I ordered up a pair of the Seakamp 4" caps from Fisheries supply. About$20 each including the new gasket. Should be a direct fit.

    Must be different than mine! My cap was $99 plus shipping.
