Dual material Y-connector

A dual material Y-connector for use in connection with medical tubing systems and the like includes an inner core made of a first material such as a rigid plastic material and an over-layer made of a second material such as a pliable thermoplastic elastomer. The Y-connector comprises a primary arm, a secondary arm and a convergence arm all in fluid communication with one another and may include a tubing segment bonded to the Y-connector convergence arm. The first material can be a transparent copolyester and the second material can be a translucent thermoplastic elastomer. Threaded caps having a multi-indentation configuration can be tethered to one or more arms and be configured to seal one or more Y-connector ports. 种与医疗管路系统等结合使用的双材料Y形连接器，其包括由第材料如硬质塑料材料制成的内芯和由第二材料如柔性热塑性弹性体制成的覆盖层。Y形连接器包括均彼此流体连通的主臂、副臂和会聚臂，并且可包括连接至Y形连接器会聚臂的管段。第材料可以是透明共聚酯，第二材料可以是半透明热塑性弹性体。具有多压痕构型的螺纹盖可系连至个或多个臂且被构造用于密封个或多个Y形连接器口。
