MBK Polyester Support Rings for Hydraulic Seals
MBK Polyester Support Rings for Hydraulic Seals
MBK polyester support rings are designed for use as back-up rings in static sealing applications, particularly in hydraulic and mechanical systems. These rings help prevent extrusion and improve the performance of O-rings under high pressure. Suitable for Irish engineers, mechanics, and workshop professionals, MBK support rings are a reliable choice for maintaining equipment integrity and extending seal life in demanding environments.
Key features & uses
- MBK support rings are made from durable polyester (PET) for excellent chemical and wear resistance. Commonly used in hydraulic cylinders, pumps, and static sealing assemblies to support O-rings and prevent seal failure under pressure.
