I've read what thread's I could readily find on sealing threaded NP(T) pipe connections, Tape/dope etc etc, does the same apply to NP(S) connections? IF not what are some suggestions, It's for a raw water intake, 1/2" NPS bronze Perko.
First of all read this and then consider up sizing your intake to 3/4". The industry has wisely mostly moved away from 1/2 for proper seacocks. You can still find them but they plug quicker and can't often supply enough flow for engine cooling. Groco, Apollo & Buck Algonquin, among others, no longer make proper seacocks in 1/2". You can still find Marelon flanged seacocks in 1/2" but, again, they tend to plug up easier.Thanks Tim and Winkfish. Yes I had already read the whole pipe dope and tape conversation, great information which is exactly what prompted my question regarding sealing techniques for NPS (straight) threaded connections. I've searched the internet over looking for a flanged seacock or seacock adapter to thread onto the 1/2" NPS threads associated with the already mentioned Perko intake strainer but am unable to find one under 3/4". I really want to replace the NPT threaded ball valve which is currently in place. The only thing I can find is a Marelon 1/2" NPS ball valve. So, back to my original question....
Thanks
