    0.385" Bore Diameter Socket-Weld Design Thermowells
    Application:
    260W series fits standard length 1/4' diameter elements. 385W series fits standard length 3/8' diameter elements.

    Connection:
    3/4' or 1' nominal pipe size welding shoulder fits ASA welding fittings, flanges, etc. Wells for larger pipe size fittings are available upon request.

    Materials:
    Carbon Steel (C-1018); A.I.S.I. 304 & A.I.S.I. 316 are standard. Other materials are available upon request.

    Lagging Extension:
    When specifying lagging extension, choose a length which will permit the use of a standard element length. (See 260L and 385L lengths.)

    Series 385W
    All dimensions in inches.

    * NPSM internal pipe thread will accept both NPT and NPS male threads.

    Where single values appear in the velocity tables, these may be considered safe for water, steam, air or gas. In the shorter insertion lengths, consideration is given to the velocity pressure effect of water flowing at higher velocities. The values in parentheses, therefore, represent safe values for water flow, while the unbracketed values may be used for steam, air, gas and similar density fluids.
