General-service Braided Synthetic Packings
John Crane styles 1330, 1332, 1335 and C1061 are cost-effective general-service packings constructed of the highest-quality synthetic fibers and lubricants. These products are designed to handle a wide range of fluids at moderate to high temperatures, pressures and shaft speeds. These styles are thoroughly impregnated with PTFE to enhance chemical resistance, lubricity and dimensional stability. This helps to ensure even gland load distribution and to promote longer packing life.
