    • A fitting incorporating a crimp sealing device and a method of forming a seal between a length of corrugated tubing and the fitting are provided. A sealing crimp is formed over at least one corrugation of the tubing, where the sealing crimp can utilize a preformed bend or bulge to form a crimp and seal. Alternatively, the sealing crimp can apply pressure radially against an outer sleeve of the fitting, such that at least one corrugation of the tubing is compressed axially or radially to form a primary seal. The outer sleeve also can include one or more gaskets arranged between the outer sleeve and the tubing for forming a secondary seal. An inner sleeve can be received radially inside the outer sleeve, and one or more gaskets can be arranged between the inner sleeve and the tubing. Further, a jacket crimp can be applied against an end of the sleeve member to contact a jacket that at least partially covers the tubing.
    • 提供了一种装配有卷边密封装置的配件以及在一段波纹管和配件之间形成密封的方法。 在管道的至少一个波纹上形成密封卷边,其中密封卷边可利用预先形成的弯曲或凸起形成卷边和密封。 或者,密封卷边可以径向地对配件的外套筒施加压力,使得管道的至少一个波纹轴向或径向地压缩以形成主密封。 外套管还可以包括布置在外套管和管道之间用于形成辅助密封件的一个或多个垫圈。 内套筒可以径向接收在外套筒内部,并且一个或多个垫圈可以布置在内套筒和管道之间。 此外,夹套卷曲可抵靠套筒构件的端部施加以接触至少部分地覆盖管道的护套。
