Stopcock Plug Retainers
Keeps KONTESĀ® brand stopcock plugs in place under adjustable tension. The retainer and ethylene-propylene o-ring are slipped over the end of the plug. Cross cuts at the end of the retainer enable the threaded portion to expand and then snap into place. The o-ring and nut are then moved toward the stopcock barrel to provide a spring loading effect which secures the assembly. Material is polyacetal.
