Elastemer sealing rings..Opinions

leroy

Any opinion on elastemer sealing rings being used on WM hw boilers.Which is better in your opinion push nipples or rings .Any body have experiance with any leaks on WM hot water boilers and are they the only ones who use ESRings in between boiler sections.Thanks.

The boilers


I currently use do not have rings. That being said, I have installed hundreds of W/M boilers and have never seen one leak because of the rings.

Peerless uses them too.

I would not discount a boiler simply because of the "ring vs. nipple" debate.

Hope this helps.

Rings

I've seen leaks in 66/68 steam boilers but not in FHW. Also the section design in the Gold series is an improvement. More machined surfaces, less wear from expansion. I believe they called it captured seal design. Hard to describe without a picture.

peerless

most peerless boilers use steel push nipples, the pinnicle being the exception

love the ec/ect for stm, larger water volume than most for a given firing rate

the best part about rings is if you have to section a boiler to get it into a basement all you need is silicone and a 3/4"socket and torgue wrench

rings

Ditto on the other comments. I've used WM for years (hundreds of boilers) and never a leaker!!!!! They're great when you have to add a section for expansion or when the owner removes all the asbestos pipe covering and won't re-insulated. Can't beat 'em.
