Specification of CHESTERTON 412-W Multi-Service
412-W
Multi-Service
Chesterton 412-W combines a newly developed synthetic composite yarn with
a specially formulated break-in lubricant. Continuous filament center provides
ten times the tensile strength of typical packing fibers. Fibrous covering enables
412-W to absorb twice the PTFE blocking agents of conventional packings.
Chesterton interbraid construction helps prevent migration of blocking agents
so that 412-W maintains density to prevent wicking throughout its service life.
412-W also incorporates a purified colloidal lubricant to prevent failure at start-up
and maintain continuous lubrication throughout the break-in process.
