The fittings shown in the picture are definitely Quest and they are still manufactured and available. I just had to redo my Raritan hot water tank connections in a new tank install and had no problem getting them through the marina work shop and a local marine store.( not carried by West Marine) I also had leaks as I had to use some old non Quest ¾ to ½ plastic reducers at the tank connection and used a product called Stop Leak to seal the joints which did the job. The local yard mechanic loaned me his sealant made especially for plastic. Hope this helps.

But I will point out that teflon tape is useless as a sealing medium in compression fitting applications. In pipe thread (NPT) applications the thread contact surfaces make the seal, in compression fittings the threads simply afford a clamping force. In other words, don't try to fix this problem with a thread tape solution. Cheers, Russ Sweet 35 mk-1 At 04:14 PM 27/05/2015, you wrote: New issue for me, but I hope others have run into this. Alera has a pressurize potable water system. It uses grey colored hoses and fittings throughout. All appear to be original except for those around the three way valve I replaced a few years ago. One (or possible more) of the "T" fittings where the hot and cold water runs split behind the sink to go to the sink and shower in the head have small leaks. Here's a picture - https://www.flickr.com/photos/37365243@N00/17989742489/in/dateposted-public/ The leaks are not enough to be a huge problem in terms of volume. But, they leak out from behind the bulkhead into the floor of the head scandalizing the Admiral and making gett8ng them fixed a high priority. Also, I suspect that I may have, or will have, similar issues at other junctures that I have not discovered yet. According to my brother, who has a CS40 at Niagara on the Lake with a similar set up, this grey stuff was all the rage, including in residential applications, until they learned that it started to deteriorate after 20 years or so, developing hair line cracks and leaks. The company is now out of business, of course. These are in a difficult location and appear to have been done originally without any silicon tape sealant. I can probably get a wrench on them but am worried that if I can to either tighten them or loosen them to put on the tape sealant before tightening em back up until they stop leaking, they'll break. Thus, turning a small problem into a big one. Now to my actual question... What do you think of using a sealant on these after a thorough cleaning and drying process? Has anyone done this successfully? If so, what did you use? If not, (this ought to be a good one) what sealant would you suggest I try? (My Brother Tony suggested 3m 4200, but I'm not sure about that one) As always, suggestions, stories and wise-assed remarks are all welcome! thx Tom B Tom Buscaglia SV Alera 1990 C&C 37+/40 Vashon Island WA (206) 463-9200 www.sv-alera.com <http://www.sv-alera.com/> _______________________________________________ Email address: CnC-List@cnc-list.com To change your list preferences, including unsubscribing -- go to the bottom of page at: http://cnc-list.com/mailman/listinfo/cnc-list_cnc-list.com
