As a leading China SWG ring manufacturer, Kaxite produces complete ring sets — inner rings, outer rings, and matched pairs — with precision punching and CNC machining to meet the most demanding piping specifications.
Inner and outer rings for spiral wound gaskets are essential metallic components that provide structural support and positioning. The outer ring (centering ring) locates the gasket within the flange bolt circle and prevents over-compression of the winding. The inner ring (retaining ring) protects the winding from erosion in high-velocity or turbulent flow services, and provides additional sealing support in vacuum applications.
Kaxite offers a complete range of SWG ring sets in sizes from 1/2" to 24" (DN15 to DN600), with options for zinc coating, powder coating, or grooving to suit specific application requirements. Our monthly production capacity exceeds 300,000 pieces, ensuring reliable supply for both scheduled maintenance and large-scale project demands.
