Born from the need for a hygiene-friendly and durable fitting, the SP Elbow was the first version of the SP Tap and was designed for use in hospitals and similar institutions. Like the SP fitting, the SP Elbow was designed by Otto Sparre-Petersen, engineer and machine technician at Gentofte Hospital. Otto had become tired of maintaining the old fittings and therefore developed a new and more durable thermostatic valve that could withstand heavy pressure loads. Based on traditional craft, the SP Elbow remains a beloved classic used in public institutions and private homes alike.
