Flexible Metallic Packing

Styles 1600N, 100CU, 100AL and 124 are flexible metallic or crinkled packings designed for a wide variety of high-speed, temperature, pressure and viscosity applications.

These strong, compressible packings demonstrate remarkably good shaft conformability and low friction characteristics for metallic packings.
