    there is one for ea. line size to check superheat or add a lp or hp
    you can soft solder them on or braze. I soft solder them to keep from burning the oil.

    let me know what you think

    I`m not sure if I`m reading this right but are you saying you solder these to a pressurised system. Just think of the consequences if the pipe burns through

    will not burn through copper I'm not using ox acct here
    just soft solder but funny

    they are made for this just look @ them Google it
    Melting Point: 1083.0 °C (1356.15 K, 1981.4 °F)
    he behavior of tin-lead solder is shown by the diagram in figure 6-8. This diagram shows that 100% lead melts at 621°F and 100% tin melts at 450°F. Solders that contain 19.5% to 97.5% tin remain a solid until they exceed 360°F. The eutectic composition for tin-lead solder is about 63% tin and 37% lead. (“Eutectic” means the point in an alloy system that all the parts melt at the same temperature.) A 63/37 solder becomes completely liquid at 361°F. Other compositions do not. Instead, they remain in the pasty stage until the temperature increases to the melting point of the other alloy. For instance, 50/50 solder has a solid temperature of 361°F and a liquid temperature range of 417°F.
