Premium Oilfield Technologies carries complete cartridge assemblies for the major brands of top drives and swivels. We recommend carrying an extra assembly on standby for quick turnaround and reduced downtime.

Our washpipes are chrome plated and ground to a fine finish ensuring a tight seal and reduced friction. Washpipe packing is molded using rubber impregnated fabric to increase durability and longevity.

All of our parts are interchangeable on a part-to-part and unit-to-unit basis.
