Дополнительное уплотнительное кольцо заглушки блока крепления Caterpillar 4C6242

The Holding Block Plug Backup Seal Ring works as a secondary sealing element that limits extrusion of the primary seal under pressure. Providing structural support behind the main seal, it helps maintain sealing integrity during pressure variation and repeated operating cycles. The backup seal ring manages interface deformation by distributing load evenly across the sealing area. Its functional role supports controlled fluid containment, stable sealing engagement, and predictable performance by managing seal support and interface stability within the holding block assembly.Attributes:• Manages load distribution at the seal interface.• Helps control fluid migration at the plug connection point.• Maintains sealing integrity during pressure variation.Applications: The Holding Block Plug Backup Seal Ring is used within holding block assemblies to reinforce primary seal function and support controlled fluid containment at the plug interface during operation.
