Leaking Lazarette Hatch

CAVU · Posted: Tue May 17, 2005 11:25 pm Post subject: Leaking Lazarette Hatch

The port lazarette hatch leaks on my 22 cruiser. I removed the gasket and it has a slight defect which I think is causing the leak. My research so far seems to show it is a Bomar inspection hatch? Has any one found a source of new gaskets? I could only find one source that sells the material in 10' lengths for $25. That seems a little high to me since I could buy a whole new hatch for $55. Any ideas for alternate gasket material? I did find a source for 0-ring cord in 3/8" OD which would fit in the hatch groove. Not sure if this would seal properly. Any help/ideas would be appreciated. Thanks.

Thanks Dan. I didn't ask what it was made of. I will have to call again tomorrow and check. The old gasket was pretty soft and squishy so a very hard material probably wouldn't work.

The O-ring cord (if it is soft and durable enough) will work just fine. In a previous place of employment we had a kit that could be used to make custom o-ring of most any size - it consisted of:
1) various diameters of o-ring cord
2) a simple device with channels in it for each diameter of cord and a slot through which a razor blade would fit - this allowed one to easily make nice perpendicular cuts on the cord
3) Some "super glue - like" glue to glue the ends together and
4) a jig that would keep the ends aligned while gluing.

I beleive the kit was from Parker O-rings. BTW - it is also possible to get the cord in a design that is flat on two sides. A good source for O-ring parts (and for all kinds of other hardware) is McMaster Carr. Go to their web site (www.mcmastercarr.com) and do a search on o-rings - a lot of good information on types of cord stock, hardness, material type etc will come back as will links to products. Scroll down and you'll see links to their o-ring splicing kits. You can also view and price these by going directly to their catalog pages - page 3238 of thier courrent catalog has the splice kits listed. The "inch kit" in silicone "includes four 7-ft. long pieces of cord stock in diameters of 0.103", 0.139", 0.210", and 0.275" (unless noted)", goes for $46.67 and includes a simple jig and glue.

I might also point out that McMaster Carr is also great source for other hardware including stuff made from stainless.

Thanks R-bum. Thats Mcmaster-carr. The extra 'r' seems to be important in linking to the site!

You may want to edit your post as well, as "misspelled" has two 's's!
(sorry, I couldn't resist; I love this one.)

Thanks guys. While you were deciding how to spell McMaster-Carr, I checked out the web site and you are right-a lot interesting stuff. I found a source for o-rings locally but they only had Buna-N which was very hard. I was afraid it would not work. I finally settled on some foam weather strip from NAPA. Seems ok with just a hose test. I'll know more after a good hard rain. Thanks.

HI Ken I am glad you mention those leaky Bomar hatchs , on my 22 2005 both side leaks like sieve. My theory is that the surface where the flange is screwed is not totaly level , and the lock mechanism does not tork the door thighted enough. So if you use different O ring and it work please tell us thank you . I love this this C Brat forum. Gary & Sharon

Ditto on my hatch's. Both leak significantly and from the sound of things a lot of us are candidates for a "group" leak fix. I've had it on my agenda to troubleshoot but have been too busy to get to it as yet.

Well the news is not good. I thought I had the leak fixed with the soft foam weatherstrip from NAPA. After a couple of hard rains, it is still leaking. I may have to spring for the manufacturers OEM gasket. It is very spendy.

On my 2005 the port hatch leaks but the starboard is fine. I guess I need to see what the difference is between them and maybe the cause the leak will show itself.
