    Fitting question

    About 25 years ago I plumber friend of mine noticed a street ell in a gas piping system I did. I was told that you shouldn't ever use St. ells in a gas system because the male section of it has a reduced inside diameter than regular pipe.
    Well 25 years later I just heard the same thing
    BTW the inspector never said anything and only now did I hear this again.
    Truth or fiction?

    Fittings

    Here in NJ, the local gas utility uses A LOT of street fittings. I personally think the same as what you have heard. They do cause a restriction. And, they are more difficult to tighten with a wrench.

    Street ftgs

    My old boss taught me to only use street el's and street 45's only when absolutely necessary for the same reason

    Close

    If your piping it that close that a street fitting makes a difference. Bump it up a pipe size problem solved.

    In my gas class

    They told me it was because there is no ability in a street fitting to bend and stretch if the building collapses, same thinking with a close nipple that is all thread, if the building crashes down it will break spilling gas. I said if that was the case why are they made? Instructor just said just don't use them...? I like your reason better, but when I absolutely need it I use them.

    If the building falls

    I don't think it much matters what fittings were used somethings going to break, especially with the crap pipe and fitting being sold lately.

    Prohibited practice

    We in Canada specifically prohibit street elbows and tees. NFPA 54 does not.

    Q?

    The measurements of the st. ell part is different than the gas pipe itself?

    No T's in Canada? How?

    Nesting Bushings

    Henry, when you mention Nesting Bushings is that the same as saying face bushings? Thanks
