ABSTRACT:
The invention pertains to a rotary joint for transmitting fluids to or from rotating members characterized by its corrosion resistance, lightweight and tamper-proof construction. The joint includes a sheet metal stainless steel casing in which a tubular nipple is rotatably mounted upon graphite guide bearings. A nipple seal defined on the nipple engages an annular seal ring interposed between the nipple seal and a guide, and a compression spring biases the nipple and nipple seal in a direction to maintain a sealing engagement between the seal surfaces. A threaded adapter located at an end of the casing permits fluid conducting conduits to communicate with the nipple.
