CHESTERTON 412-W Multi-Service

Specification of

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.
