    • A frangible seal (40) for a fluid path including a frangible seal member secured within a tube defining the fluid path. The frangible seal member having a tubular seal member (42) and a stem (43)extending from the tubular seal member which, upon bending back and forth, breaks away from the seal member thereby to rupture the tubular seal in the fluid path. The tubular seal member and stem are integrally formed of a non-PVC material. The tubular seal member will bond to PVC tubing during steam heating thereof. The tubular seal member and stem are constructed to provide uniform non-reclosable rupturing. The stem includes vanes with spurs that frictionally engage the inner walls of the tube to maintain separation of the stem and ruptured tubular seal member.
    • 一种用于流体路径的易碎密封件(40),包括固定在限定流体路径的管子内的易碎密封件。 具有管状密封构件(42)的易碎密封构件和从管状密封构件延伸的杆(43),其在前后弯曲时从密封构件脱离,从而破坏流体路径中的管状密封件。 管状密封构件和杆由非PVC材料一体地形成。 在其蒸汽加热期间,管状密封件将结合到PVC管。 管状密封构件和杆被构造成提供均匀的不可重新闭合的破裂。 杆包括具有摩擦地接合管的内壁的带齿的叶片,以保持杆和破裂的管状密封构件的分离。
