Trying to find a strange fitting

JackmartinJackmartin Posts: 112Member
I have consulted my 1934 Hoffman heating catalog and of course they list 22.5 degree screwed black fittings. We need 22.5 one inch screwed black fittings for a steam job. The only other recourse we have is to use one inch type L copper tube and dielectric unions. I do not like using copper on steam it is not the correct material. In the event anyone knows someone or a dealer that still has/ or makes these fittings I want to purchase them. I know from experience we are all pack rats when it comes to material ,so if anyone has some in their old fitting boxes I would be delighted to purchase them from you. Thank you and all the best Jack Canada

    That says temp range from -20 to 150 degrees. That would work on a condensate return but may not on a steam supply?

    Those are 300# fittings. That's why they're expensive, but they'll work just fine.

    Er Fred, you feeling ok?

    It's a cast iron fitting. Its probably safe to say those temperature specs are a mistake.

    Er @ChrisJ , not all cast iron is created equal. I've seen cast iron waste pipe crack from excessive heat. It is always better to ask the question first, then do the work than to do the work, then say Wow, why'd that happen?

    It's not a cast iron poop pipe.

    The spec is not a mistake. All of the Zoro cast iron fittings say -20 to 150 degrees. I will accept @Ironman 's knowledge/experience, you, not so much :neutral:

    All cast iron fittings on Zoro have the same spec, and yet you feel it's not a mistake.

    Uh, actually, 300# fittings are malleable iron; 150# are cast. You can break a cast fitting with two hammers; a malleable fitting, you'll be beating for a long time.

    I'm not sure what the difference is but they claim this is 125 not 150.

    It's rated up to 150F @ 175 PSI.

    That's where that spec comes from.

    I think it's a temperature/ pressure relationship. Check with the manufacturer for clarification.

    What I'm seeing here is a contradiction.

    The temperature of steam at the spec of 125 PSIG is just over 352° F.

    Yet the Temp. Range spec shows a maximum of 150° F.

    I think someone typed something in wrong. Check with the manufacturer.

    Zoro is not the manufacturer, Anvil is.

    I think that explains some of the confusion. Also, the pic is showing what appears to be a 300# malleable Ell while the description says it's cast.

    Check with the manufacture, but it will work fine with steam. I've yet to see an iron fitting that couldn't take 215* steam.

    I also think hot rod's explanation makes the most sense. We're living in a day when everything has to be rated 9 ways from Sunday. This is what lawyers and politicians have created.

    Thank you for the information it is greatly appreciated. I owe one and all an apology the book I was looking at when I wanted to see if the deadmen had these fittings was. The Crane Cataloque circa 1924. This book is one of my favourite books to go to ,when I see something weird and wonderful ,and I do not have a clue what it is. I have to say in the days of the deadmen ,they did things in an elegant way. The book is over three hundred pages ,high quality glossey paper, and bound like an expensive novel. In my own defense .I said it was Hoffman and I cannot tell you why. I would suppose it has something to with bring an old phart. All the best Jack Canada

    Did you find one? I order them from Ferguson Enterprises once in awhile; they have MI, CI, and forged. Forged is cheaper than CI for some reason.... MI and CI are both Anvil, but I don't recall the forged MFG
