design history
access and handhole Covers
P Compressors, Styles A and B, were produced with the
access and handhole covers machined from two different
castings through September 2001. The flange thickness
of the access cover is greater than that of the handhole
covers and requires longer screws.
Beginning in October 2001, P Compressors use only ac-
cess covers. Handhole covers will no longer be produced
and should not, under any circumstances, be used to ser-
vice P compressors produced after September 2001.
The access cover flange is nominally
.17 inch (.13 - .21 inch) thicker than
the handhole cover flange. The screw
used with the access cover is nomi-
nally .25 inch (.19 - .31 inch) longer
than the screw used with the handhole
cover. The shorter screw, previously
specified for use with the handhole
cover, may not have adequate thread
engagement if used with the access
cover. The longer screw, specified for
use with the access cover, may “bot-
tom out” in the threaded hole tapped
for the shorter screw. Make certain
all of the sixteen (16) longer screws,
securing an access cover replacing a
handhole cover, do NOT “BOTTOM
OUT”. Increase the depth of the
threaded hole by manually tapping ad-
ditional threads if necessary. Failure
to observe this precaution may result
in gasket leaks.
