High Pressure Washpipe Packing

Kalsi-brand high pressure washpipe packing rings were developed to accommodate the higher speed and pressure conditions encountered in the modern oilfield drilling environment. Interchangeable with conventional oilfield packing, the unique geometry of our high-performance washpipe packing provides cooler operation and longer life through improved lubrication of the dynamic sealing interface. Contact Kalsi Engineering for information on spacer design, washpipe assembly, and greasing practices. Not recommended for temperatures greater than 275°F  (135°C).
