Hi All,
I have a 493 - 3/4" Perko water strainer (1990) for my AC. I am replacing the cork gaskets. I received the correct size gaskets but wrong material- rubber. My strainers have cork gaskets. I noticed the rubber gaskets fit perfectly....no leaks! I called Perko and was informed that even though the rubber gaskets fit, you MUST use the cork gaskets! Anyone have a clue as to why?
Thanks,

Tell me. I’ve been replacing with rubber for years. Maybe it’s because Perko doesn’t sell rubber??
That's exactly what my response would have been. When I purchased BEATs Therapy it had cork throughout but I have made my own rubber gaskets when they needed replaced and have had 0 problems. Have done the same with all my raw water connections around the pump.Quote:

I started using on the boat about 5 years ago and I have not had to replace any more Perko gaskets. Also use it on a number of other items with good success. Extended the life of DD impellers. Also use it on the rubber impeller gasket and it has enabled me to reuse the gasket when replacing the impeller or checking for wear. I have been very impressed with how it protects.
You can buy it at any good pool store, HD/Lowes, Amazon, etc..
Will magic lube prevent other things from shriveling up and shrinking from age?
Asking for a friend.
I make mine out of red silicone rubber sheet. Buy it at McMaster Carr.
The silicone rubber never dries out no matter what, lightly grease the surfaces for easier removal later.
