Pacific Seacraft Portlight Gaskets

[SVArgo]

Some time ago I thought that there was a thread, or the old email distro, on the gaskets to replace on the bronze/stainless portlights.

I thought someone had a size and spec for them and said it could be ordered through McMastet-Carr.

Does anyone have knowledge of that or could point me in the right direction?

Cheers,
Ryan

I think that was me... I ended up with a rubber tube from McMaster Carr - I think 3/8" diameter... 3 years later and they still seem to be holding up well. Not sure I can dig up more specifics about the gaskets, but will forward anything I find.

i think it depends on our port types. I have the "old" oval style and think they take 5/16 square gasket material. I could be wrong though as i'm doing this off the top of my head. JP may have PSC portlight gaskets all figures out though

I also used the McMaster Carr 5/16" square silicone bar. Here is the ordering information:

5508T25 SILICONE RUBBER BAR, 5/8" THICK, 5/8" WIDTH, 60A DUROMETER

John,

Thanks, that's it. I actually randomly came across that info this morning in the old email distro!

Since this is a job we need to do on Jo Beth, I checked the McMaster-Carr site for info and found the part # has changed. here's what I got:

Extreme-Temperature Silicone Rubber 5/8" Thick, 5/8" Width, 60A Durometer
This item is no longer available. We suggest:

5508T45

Differences:

5508T45
Tensile Strength: 700 PSI

5508T25
Tensile Strength: 1000 PSI

A slight difference in tensile strength, no biggie I suppose. Thought I'd post as a FYI...

Would this same size work for oval bronze portlights in a 78 PSC25? Just took them apart last night.

I'm gonna save the info in this thread for a future date I have to replace my gaskets. It's great that the PSC Community here at sailnet is so active and helpful.

Bill:
Thanks for the McMaster replacement p/n. FYI, it appears that the replacement gasket is red in color. Link here.

Summercamp:
I'd suggest measuring the actual gasket off your PSC25 if you've got them apart already.

Thanks - I didn't even look at the color!

Hey folks,

Good info here.

One suggestion when posting supply/source info, is to clarify which style portlights/gaskets you are referring to. I.e., the older style "ovals" or the newer style "rectangulars".

I think the gasket size and shape will be different for each.


P.S. By the way, here is some contact info for Whitewater MArine, the O.E.M. supplier for the older style oval portlights. I was able to get perfect-fit replacement gaskets from them when I rebuilt the portlights on our Dana 24 a number of years ago, at a very reasonable cost. I haven't had need to contact them lately, so I don't know how current this info is:
