John Crane styles 1320, 1336, and 1340 are cost effective graphited general service packing 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 packings are thoroughly impregnated with lubricants to fill braided voids in order to reduce product penetration. An external graphite coating is added for lubricity and to enhance heat dissipation for increased packing life.
