bundle. These wire types are XPI, MF-PTFE, PI/PTFE, and PI/PTFE alloy wire types (codes 3,
7, 10, and 11, respectively). The wear on the XPI wire type (code 3) was moderate when mixed
with XLETFE (code 4) (see figure D-10 in appendix D) compared to a low amount of wear in
the nonmixed bundle. The wear on the MF-PTFE, PI/PTFE, and PI/PTFE alloy wires was low in
both the mixed and nonmixed conditions. These combinations are discussed below.
• 3, 4 (XPI, XLETFE): XPI is slightly more damaged in the mixed configuration than in
the baseline bundle.
• 1, 7 (PVC/glass/nylon, MF-PTFE): Both wires showed very little damage, but the MFPTFE
had slightly more damage in the mixed bundle.
• 2, 7 (PI, MF-PTFE): MF-PTFE is damage more than in its baseline, but the damage
rating on the PI is higher for both the mixed and nonmixed bundles.
• 7, 10 (MF-PTFE, PI/PTFE): Both wires showed very little damage, but the MF-PTFE
had slightly more damage in the mixed bundle.
• 3, 10 (XPI, PI/PTFE): XPI in the mixed configuration exhibited slightly less damage
than in the nonmixed bundle, but PI/PTFE suffered slightly more than in the nonmixed
bundle.

• 4, 11 (XLETFE, PI/PTFE alloy): Both wires showed very little damage, but the PI/PTFE
alloy had slightly more damage in the mixed bundle.
• 10, 11 (PI/PTFE, PI/PTFE alloy): Both wire types showed a slight increase in the
damage when mixed together. When compared to each other, the two wire types showed
similar wear, whether in the mixed or nonmixed bundles.

FIGURE 28. WIRE INTERACTIONS IN GROUP IIF MIXED BUNDLES
Overall, PI, XPI, and PTFE/glass wire types (codes 2, 3, and 9, respectively) exhibited moderate
wear on the bundles soaked in hydraulic fluid, but the wear was similar or less severe in the
mixed bundle than in the nonmixed bundle for PI and PTFE/glass wires (see figures 21, 25, 29,
and 30, and figure D-11 in appendix D). The wear on the XPI wire in the bundle with XLETFE
was slightly worse than in the nonmixed bundle (see figure 22).

For the bundles containing metal shavings, figures 31 through 38 provide graphical
representations of the wire-to-wire wear for each wire type when mixed with other types.
