Product Description
Magcobar — historically a division of Dresser Industries and operated as Dresser-Magcobar — manufactured and sold through the 1950s into the mid-1980s a line of drilling-mud asbestos viscosifier additives under the trade names Magco-Fiber and Magcofiber. Magcobar was, along with Baroid and IMCO Services, one of the three principal U.S. suppliers of dry chrysotile asbestos fiber packaged for direct rig-floor addition to drilling mud systems.
Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that Magcobar asbestos drilling-mud additives exposed rig hands, mud engineers, and oilfield laborers to substantial respirable chrysotile fiber concentrations during sack opening, mud-pit dispensing, and handling — and that Dresser Industries marketed and distributed these products through the documented era despite the well-known asbestos health hazard.
Magcobar / Dresser-Magcobar has been named as a Manufacturer Defendant in publicly filed U.S. asbestos personal-injury and wrongful-death litigation.
