Buckshot Bear Posted March 25 Share Posted March 25 I have a badly leaking Hornady Cyclone rotary wet tumbler, I've contacted Lyman and they wrote back to use Vaseline around the rubber gasket/lid. This caused a big mess with pins stuck in the Vaseline and now either the Vaseline has reacted to the rubber or its from me trying to screw the lid on as tight as possible but the gasket is so stretched and oversize I can't screw the lid on as it won't catch the threads. This is one best things I've ever added to my reloading room, except for the darn leaking problem. Unfortunately the rubber gasket Part # LY-7631451 is currently out of stock with the Australian importer and months away for the next delivery. Has anyone else had this problem with theirs?

Old Man Graybeard Posted March 25 Share Posted March 25 It would fit a bit differently...but could you put an o ring in instead of the flat gasket? 2 Quote Link to comment Share on other sites More sharing options...

Buckshot Bear Posted March 26 Author Share Posted March 26 And ordered, there was one sitting in a parts bin out back and will be in the mail in the next hour and hopefully get it before Good Friday. I'll just have to order one of these yearly and add the expense in the 'fun' column. Had the tumbler roughly 2 years and probably the gasket started acting up 6 months ago (it gets used a LOT). The main importer of Lyman (not Safari they are resellers) said they do send out a lot of these as replacements to stores. I will make a template out of cardboard with the new one though and see if I can buy some flat sheet to give cutting out a few a go. .... 2 1 Quote Link to comment Share on other sites More sharing options...
Lazy Eeyour Posted March 26 Share Posted March 26 Don’t over tighten as it just distorts the gasket. You might try silicone spray as a lube for the gasket. 1 Quote Link to comment Share on other sites More sharing options...
Sedalia Dave Posted March 26 Share Posted March 26 Be sure there are no defects in the area where the gasket sits. If there lightly sand the mating surface to remove the defects. The best lubricant is the same soap you are using on the brass. 2 Quote Link to comment Share on other sites More sharing options...
Frontier Lone Rider Posted March 26 Share Posted March 26 (edited) I sanded the mating surfaces to ensure there are no defects or bumps, then seal the gasket with Dawn dish Soap, which is what I add for tumbling.

Dave I did a search about a year or more ago where I saw that you mentioned doing that in a thread. I did take some of the moulding dags off with a sharp knife and put the barrel open down on a sheet of wet & dry on some plate glass. 1 Quote Link to comment Share on other sites More sharing options...
The Original Lumpy Gritz Posted March 26 Share Posted March 26 Do you have a farm/ranch supply store near you? They might have an 'O' ring that would work. Quote Link to comment Share on other sites More sharing options...

I've had the same results with Vaseline on water filter o rings. Worked once, but then the o ring was all stretched out and wouldn't fit in the groove anymore. 1 Quote Link to comment Share on other sites More sharing options...

You end up over tightening the lid to get it to seal which causes it to stretch even more. With the new gasket, make sure it is lubed on both sides with soapy water. Then put the lid on till it is just snug. See if it leaks. If it does, tighten down in small increments until it stops leaking. Over tightening can cause it to leak worse than if it is too loose. 1 Quote Link to comment Share on other sites More sharing options...
Von Dutch, SASS # 7995 Posted March 26 Share Posted March 26 If you use vaseline to lube the rubber the oils in the vaseline will attack the rubber! I have the large Frankford arsenal rotary tumbler and it came with silicone gaskets its 10 years old and I have had no leak problems, if they still come with silicone gasket maybe they are the size you need its 3/8 wide 1/8 thick ID 3 7/8 OD 4 3/4? If you use rubber get some food grade silicone to lube the gaskets. V.D. Quote Link to comment Share on other sites More sharing options...
Brushy Creek Bill, SASS # 49466 Posted March 26 Share Posted March 26 I had the same exact problem with mine, oversized and hard to seal almost from day one. And of course, out of stock or not available. I ordered a 3 pack set of 6"X6" X 1/8" thick Silicone Ruber smooth gasket material off of Amazon. Cut a new one using the lid as a pattern, never have had a problem since. Brushy 1 3 Quote Link to comment Share on other sites More sharing options...

Taos Posted March 30 Share Posted March 30 If it were me? I'd visit a few hardware stores or auto part stores and buy a piece of rubber gasket material and cut my own new gasket. 2 Quote Link to comment Share on other sites More sharing options...
