SPLIT COLLET SHOULD EASILY MATE WITH TEST PIECE. FORCING THE CONNECTOR
WILL RESULT IN POOR SEALING AND POSSIBLE LEAKAGE. DO NOT TURN OR
ROTATE CONNECTOR AFTER THE COLLETS HAVE GRIPPED TEST PART. DAMAGE TO
TEST PIECE AND THE CONNECTOR’S INTERNAL PARTS MAY RESULT.
3. Make sure green ring indicator is exposed as shown.

pressurized media.
5. Activate test media through connector back port. Pressure will enhance the seat.
6. To disconnect from test piece, deactivate test pressure. Slide knurled sleeve away from
test piece to expand collets. Remove connector from test piece.
MAIN SEAL REPLACEMENT:

THE STEPS THAT FOLLOW. IF CONNECTOR MUST BE DIS-ASSEMBLED TO
REPLACE MAIN SEAL, SEE INSTRUCTION WP122.
1. Slide sleeve back allowing collets/jaws to open. This will help expose the end of the piston
to extract main seal.
2. Using a pick like tool or small flat blade screwdriver, remove main seal from piston and
discard.
3. Use caution not to scratch the main
seal groove surfaces in piston.
4. Install new main seal using your fingers or a non-marring tool. DO NOT LUBRICATE!
5. Make sure main seal is properly seated.
CAUTION: 60 & 70 Connectors are not internally valved. Disconnecting while pressurized
can cause rapid separation and high velocity loss of media.
MAINTENANCE:
Periodically inspect connector and seal for proper operation. Repair or replace parts as
required to assure positive sealing and performance.
Establish a regular interval for lubrication. The media and environment will be determining
factors in establishing this interval to prevent dryness and/or corrosion.
Difficulty of operation after continual use indicates need for lubrication or other
maintenance. Repair parts, instructions and tools are available. Please contact your
FasTest Distributor or the factory for assistance.
