Slack Adjusters

Overview | Features & Benefits | Water Resistant Slack Adjuster

A mechanical, double-acting, automatic tension slack adjuster regulates brake cylinder piston travel on rail freight cars. The AAR defines various groups of slack adjusters to differentiate functionality.

NYAB’s automatic, double-acting, AAR-approved slack adjusters for freight car applications require no servicing between overhauls.

Designed for body-mounted applications, the KRD-482-E slack adjuster is also available in the Water Resistant version, KRD-482-R. Both versions are AAR S-419 compliant.
