I recently ordered two 50' rolls of the 1" (hull) to 1/4"(lexan) black rubber gaskets and locking strip used on the early 70's Morgan OI and some other Morgan portlights. My old portlight gaskets are so ozone damaged and ugly; with black steaking from the old rubber. I can't wait to receive the new gaskets and try the refit! Of course, I don't really need 100', but slightly more than 60'. I should have almost 40' of the material left over. Someone might be interested,- I'll post my results. Who else has refit OI portlights? Have you replaced the original rubber extrusion like my plan? ,-or something new and different? 'take care and joy, Aythya crew

Gasket material portlights Morgan 41

What a relief! There is actually someone who is trying to do the same thing we want to do with replacing the gaskets on the portlights.:) We have a 1973 Morgan 41 Out Island and are trying to locate where to buy the gasket material and also the correct size. I am very interested in the 40 ft. left-over if that is the correct size for my boat. Please tell me more.:D
Thanks in advance.

Sue, We are also on a '73 41OI,- The material has been delivered to my daughter's home and I'm driving up tomorrow to pick up a small sample to fit one portlight. I want to see if the flexibility is sufficient to make the 3" radius turn at the ends of the ports. Unlike the original the locking strips are black. I hope that the current product by Stanlock is identical to their 1973 production. Send me a reminder e.mail at [email protected] and I will tell you of my findings. I recall the name of your vessel,- maybe on the morgan 41 yahoo site...?? 'take care and joy, Aythya crew
(google Stanlock sealing gaskets to see the specs for the 1" to 1/4" gasket)

Thanks Aythya crew. I believe Stewart and Nancy and yes I also do know you from the Morgan 41 yahoo site!! It's a small world. I sent you the pdf on the Stan-Lock stuff not too long ago. I have emailed a distributor in California today and hope to hear from him. Thank you for your email. I will send you a reminder to find out what happened as you suggested.
Happy Sailing

Sue, Nancie & I are currently in New Smyrna Beach. I brought a sample of the gasket & lockstrip back from Jacksonville. I was concerned about the flexibility of the material. My 35 year old materials are so stiff, I thought they may have been form-molded, but the new materials are very supple. It's been raining here so I will try a refit of one port when the weather is dry. Where are you now located? -Stewart & Nancie

Hi Stewart, we are in Puerto Rico. We have been living here for the past 11 years. We bought Orion last year and are preparing for full time cruising in about 1 1/2 years. :) I got a quote from a company in Oregon for the 50 ft. roll. The shipping costs are high, almost half of the price! :eek: Anyways, I am looking forward to your reply concerning the product. The company rep in Oregon is very nice and he sent me a pdf of the gasket. He said we can return it if it does not fit. For now, we only need to replace the four big portlights in the salon. So perhaps your left-overs would be the perfect thing for us????? Hopefully you could let me know by next week, because I need to get the stuff soon, either from you or from Oregon. Regards to you and Nancy :)
Happy Sailing

Hi Sue, 'sorry to be so late in reply, but we'e been away from wireless for a while,-we're in Ft. Lauderdale now. I replaced my leaking port with the sample of new material and found that the 3" radius bend at each end was severe enough to distort the shape of the channel for the locking strip. This prevented me from being able to insert the locking strip. I have ordered the tool from Oregon and with it I may be able to suceed. The new locking strips are much more supple and I can not pry them into place by hand. Even without the locking strip my new portlight gasket no longer leaks, but I do not think the ports will be safe offshore without the locking strip. I should receive the tool when I'm in Key Largo next week. I'll keep you posted here. 'take care and joy, Stewart

Sorry to be stupid but what is a locking strip? I have a 74 33 OI and my wife just called to say most of the ports are leaking. Is there anything tricky to rebedding these ports? Does it require any caulk?

Planb835, The locking strip is the white trim insert that, from the outside of the port, increases the pressure of the gasket against the hull and the polycarbonate portlight. The new product has a more flexible locking strip that is all black, but the H-gasket extrusion is identical to the original. 'take care and joy, Aythya crew

gaskets

Hello Stewart and Nancy,
do you have any updates on the gaskets? Did you get them finished and how do they work? I had to leave for Germany and will be back end of April. My triplet brother had triple bypass surgery! He is recovering nicely. My husband will be ordering the gasket material for Orion. Just wanted to see if you had any news.

Sue, I've come to the conclusion that the original gaskets were form molded in order to make the 3" radius turn at the ends of the port. I've completed the starboard ports and inserted the locking strip across the horizontal spans of the gaskets tapering them into the curves. I did use a sealant placed inside the ends at the turns just inside the lip of the gasket where it meets the lexan. I also placed a thin layer of sealant against the 1" edge of the hull before laying in the gasket and a dab of sealant where the cut ends of the gasket meet at the top. My stainless steel marlinespike was a better tool to insert the locking strip than the plastic tool sent with my materials. I am very pleased with the outcome both in looks and integrity of the fit.

Stewart, we have just ordered the gasket material, locking strip and tool from Griffiths Rubber Mills and will receive soon. Thanks for the advice on how you installed yours. We will be keeping that in mind when we install ours. The people from Griffiths Rubber Mills were extremely helpful. Will send some pictures when we are finished. Have you made any of yours yet?
Happy Sailing!

Orionsue, 'best of luck with your project. If you run across another Morgan with the need for the whole length offer them my left over footage with yours. I'd sell under cost just to not carry my left over 40' around.

Thanks Stewart. Will keep you posted on the project and let you know with regards to the leftover gasket material. If you are ever within our waters (Ponce, Puerto Rico) make sure to let us know. Rick and I would be happy to meet you! :D
Happy Sailing!

Morgan h-channel window gasket material

I've also been trying to find the gasket material for my 36 morgan O/I. I've concluded from Orionsue, and Captainforce that the manufacture is Stanlock, and Griffiths rubber mills is a vendor. Appreciate your posting the information because I hadn't been able to locate a vendor or manufacture. If either of you has excess gasket material you'd like to sell before I contact the vendor, I'd appreciate it if you'd contact me at 352-481-2175

I do not have the website available at this time. I did buy some excess marterial from Stuart for my OI33. The tool that worked the best for me was a pair of "ring" pliers. They are used to attach and remove locking rings. I got mine from Lowe's for $19. The greatest part is they have tiny rods to slide into the gasket material and you can reverse the pliers where squeezing the handle opens the jaws. Once you play with them in the store you'll say I got to have these!

Here's my row of new portlights. They're pretty much like the original, but with black instead of white locking strips.

Ashatsea, The invoice I have for the gaskets is the Stanlock product pruchased from Griffith Rubber Mills, P.O.Box 10066, Portland, Or. 97296, Phone= (503) 226-6971.
The item # for the gasket is 31513SL with the description SL-2026 1/4 x 1
The item # for the locking strip is 37653FTSL with the description
SL-1250 Lock Strip
As you read in the above postings, the gasket replaces the original well, but there is difficulty in applying the locking strip within the 3" radius turns at the ends of the portlights.
Here are views of my portlights before and after:
