1. INTRODUCTION
This instruction sheet covers assembling a terminated
contact, housing and TPA as represented in Figure 1
and extracting the contacts from the housing.
Reasons for reissue of this instruction sheet are
provided in Section 6, REVISION SUMMARY.

2. DESCRIPTION
All VAL-U-LOK pin and socket contacts have two
flexible latches that lock into their respective housings
when fully inserted. The TPA-compatible contacts
have special features on their insulation barrels that
work in conjunction with the TPA device to ensure full
contact insertion. See Figure 2A.
The plug and receptacle housings are available in 2
through 24 positions which are arranged into 2 rows.
The TPA devices are available in 1 through 12
positions, single row, so 2 TPA devices are required
for each housing. The TPA is designed to be installed
into the housing to ensure all contacts are fully
inserted and will not back out during mating. When
fully installed, the locking latches of the TPA snap onto
raised ledges around the perimeter of the housing.
See Figure 3B.
3. ASSEMBLY
1. Ensure that the contact is properly terminated to
the wire according to the requirements provided in
Application Specification 114-13172. Check that the
flexible latches are not damaged or distorted from
their original form as shown in Figure 2A.
2. Insert the terminated contact into its respective
housing as follows:
a. Grasp the contact directly behind the
insulation barrel. Align the contact with a contact
cavity in the housing at the wire entry end as
shown in Figure 2A. Make sure that the contact is
perfectly aligned (not angled or rotated) to the
contact cavity. See Figure 2B.

CAUTION
Never insert the contact upside down; otherwise, the
locking latches could depress and lodge into the cavity
in an unseated position or become compressed so that
they will not lock when repositioned for proper insertion.
b. Push the contact straight, not rotated, into the
contact cavity. If it is rotated, damage to the
contact will occur or the contact will not latch
properly into the contact cavity. See Figure 2B.
Do not force the contact into the housing. It
should slide in and latch into position with
minimal force.
c. Ensure that the contact latches are locked into
the cavity by pulling lightly on the wire and
checking for resistance to pull out.
3. Install the TPAs into the housing as follows:
a. Align a TPA with the wire end of the housing
so that each tooth faces a contact cavity with its
radius surface against the wire. See Figure 3A.
b. Slide the TPA into the housing so that the
teeth enter the contact cavities evenly and until
all the locking latches lock onto the ledges
around the perimeter of the housing. Make sure
to push on each locking latch individually to
ensure complete installation. There will be an
audible and tactile “click”. See Figure 3B.
NOTE
TPAs with more than 5 positions have 4 locking latches.
TPAs with 5 positions or less have only 2 locking
latches. Make sure to push on each locking latch
individually to ensure complete installation.
c. Flip the housing over and repeat steps “3a”
and “3b” with a second TPA for the other row.
4. EXTRACTING CONTACTS
1. TPAs can be removed from the housing by
releasing the locking latches from the ledges and
pulling the TPA straight away from the housing. No
contact can be extracted until the TPA is removed.
2. Contacts can be removed from housings using
Extraction Tool 1586343-1 according to Instruction
Sheet 408-32114.
CAUTION
DO NOT re-insert any extracted contacts.
5. REPLACEMENT AND REPAIR
•DO NOT use defective or damaged products.
Contacts, housings, and TPAs are not repairable.
•DO NOT re-use a contact by removing the wire.
•DO NOT re-insert any contact after extracting it
from the receptacle housing.
