Resilient seal with axial protrusions

摘要: A seal comprises a body portion and one or more protrusions extending from said portion. The defines directing curve; generating curve defining shape; plurality of cross-sectional planes normal to the such that cross-sections taken along each plane have substantially shape curve. intersect planes. direction components extend transversely (that is, perpendicularly obliquely) defined plane. Most preferably, these serve resist twisting during placement use.
