PSA-NRRG-2 Introduction

• Through joint efforts with NYE Lubricants and
  JPL/NASA Laboratories working in conjunction with
  Basic-PSA, Inc., we are pleased to present
  PSA-NRRG-2 Mechanical Snubber Grease, the
  replacement grease to NRRG-159.
• Test results prove that PSA-NRRG-2 is a
  significantly superior grease for use in
  Basic-PSA Mechanical Snubbers.

Qualification / Radiation

• The radiation qualification process was performed
  to meet the requirements of Basic-PSA, Inc's
  Mechanical Snubber Design Specification.
• There was no significant change in percentage of
  weight loss in the radiated samples.
• In addition,each radiated sample remained stable
  in an oxygen environment for 24 hours at 350 F
  with no exothermic reaction.

Qualification / Evaporation

• The evaporation qualification process exceeded
  the initial prior testing of NRRG-159 in time
  exposure by approximately 2,200 hours.
• The test results for evaporation rates exposed to
  300F in an open air environment were
  considerably improved as in comparison with the
  former NRRG-159 data.

Summary
In summary, PSA-NRRG-2 is better than or equal to
the former NRRG-159 Mechanical Snubber Grease and
is the recommended replacement grease for use in
Basic-PSA Mechanical Snubbers. Through extensive
testing, the PSA-NRRG-2 is a like for like
replacement and is now available to all Basic-PSA
Mechanical Snubber users. In support of
individual Preventative Maintenance Programs.
