heat exchanger gaskets on m-25xpb

[mervdog]

My heat exchanger was leaking and I ordered new gaskets from Torrensen. Although the part number matched the gaskets were half the thickness of the original. I had to use two together to get it to seal. The new gaskets did not look like the old. Has anyone had this problem

[Roland Gendreau]

No one has responded to this one, but I have some information that might be of interest.

I recently removed the end caps of the 3 inch heat exchanger to check for debris. I then wanted to replace the old neoprene gaskets.  Torrensen does not list the gaskets, only the caps and gaskets.

I contacted Sendure and they also offer only the caps and gaskets together for about $35 each plus shipping.

Since my end caps are in very good shape, i wanted to replace only the neoprene gaskets and bolt orings.

I contacted Lenco Coolers (http://www.lencocoolers.com/)  , whom I had dealt with before when I upgraded my C30 heat exchanger from a 2 inch to a 3 inch unit.

Lenco mailed me a pair of new neoprene gaskets and o rings for less than $5.

They told me to just send them a check.

Nice folks.

Torrenson is notoriously overpriced.  Used Sendure.  Phone # and info previously posted here on the MB - search on the name should be easy.  I bougth some for a friend in Canada and smuggled them across the border for him.  No problemo - whoops, wrong border!

There is nothing high tech about making gaskets.  I make my own out of some scrap rubber roof material I picked up when then reroofed my office building, but a thick piece of inner tube should also work.  O rings are available at any hardware store.  In the worst case, a thick bead of liquid gasket should also work.  Like rebedding, apply, let it set up with light pressure then tighten fully the next day.

You can get Sem-Dure parts by calling Glen Mar Marine (800)282-0123. 
The HX on the M25XPB is the same diameter 3" as the XPA - it's just longer.

The Sendure sketch is on reply #2 here: http://c34.org/bbs/index.php/topic,3744.0.html

Not to be repetitive, Sendure does not sell the gaskets separately from the end caps.  So if your end caps are fine and you'd prefer to pay $5 for new gaskets rather then $34 for end caps and gaskets, contact Lenco Coolers as mentioned in my posting above.

Thanks, Roland, just tryin' to provide the source.

Roland is probably correct that some places will only sell the entire HX - kit that includes the end cap.  However, I've purchased just the gaskets from Glen Mar marine.
