Subject:

UNLOADER DESIGN CHANGE TUFLO 400, 500, 501, 600, 700

AND 1000 COMPRESSORS

A change in production techniques allows the elimination of the teflon back-up ring on TuFlo 400, 500, 501, 600,

700 and 1000 Compressor unloader pistons. Performance, durability and interchangeability are unaffected.

This will be phased in on a running change basis in the near future on new and remanufactured compressors and
