Stopcocks
With a ball valve, stopcocks control the flow of liquids and low pressure gases in delivery systems. Fitting into corresponding female joint parts, the plugs come in any number of bore hole arrangements. Often featuring tapered ends, a wider tube diameter range is accommodated for to increase working flexibility. The high quality, leak proof stopcocks meet vacuum applications and come in ground glass styles or plastic to eliminate the need of greasing.
