S-521PNL
No Lead Cast Brass Boiler Drain
Description
The S-521PNL no lead cast brass full pattern boiler drain with a PEX (F1807) x MGHT thread end configuration. It is equipped with a packed stem, packing nut and handwheel design. The packed stem creates a more effective seal when compared to packless-bonnet designs. The casting process uses an electric-induction furnace which optimizes molten brass temperatures, resulting in superior cast body and bonnet components.
