Chesterton 1725A Food Process Packing is constructed with expanded PTFE yarn and a specially-designed lubricant to provide superior sealing capability in rotating equipment. Its interbraid construction ensures maximum strength as well as minimal wicking of fluid through the packing. 

Chesterton 1765 is ideally suited for bleach pumps and other rotary applications requiring a white, non-staining packing. Constructed from chemically resistant, expanded PTFE material, this packing demonstrates higher speed performance capabilities than traditional PTFE materials for improved performance in a wide range of applications. Chesterton 1765 is ideal for rotary applications where chemical resistance is required and process needs to remain non-contaminated, such as ClO2 pumps, paper stock, and feeders. 

Chesterton 1730SC packing combines a resilient silicone rubber core with the heat-resistant thermoset fiber of Chesterton's MillPack 1730. The elastic, rubber core gives the packing better memory, allowing it to withstand radial shaft motion and vibration while maintaining excellent leakage control with minimal gland adjustments.

Chesterton 1740 is an inter-braided packing using DuPont™ KEVLAR® yarn with PTFE and other lubricants.* Each strand of yarn has been individually coated in order to dissipate heat. 1740 can be installed as full sets to offer combined resistance to pressure, temperature, chemicals, and wear. 1740 braided packing is also used as back-up rings for added extrusion resistance in abrasive applications.
