T型格莱圈PT密封件两侧轮廓是倾斜的且具有倒角,密封截面朝向密封面逐渐变窄。这样的截面形状能保持活塞密封,具备典型的结实感和紧凑性,而且也不会减少因压力产生的最大压缩所需要的弹性。这种特殊的T型格莱圈截面形状所具有的侧边角度,允许其有一个附加的自由度,使密封件能够轻微倾斜。于是可把最大压力点移到高压侧密封边缘的位置。相反,在密封件的低压侧出现一个没有压缩或剪切负载的中间变形区,从而有效地减少了密封圈被挤出的危险。
T型格莱圈PT系列具有极佳的静态密封性能,可允许较大的挤出间隙(约50%),视应用场合而定,故可降低加工费用。由于较大的挤出间隙,甚至在固体介质中也能安全使用,摩擦力小,无爬行现象,特别推荐用于重型和大直径的应用场合。
