Connector Maintenance:
•A daily, weekly and periodic inspection of the connector by competent person is
recommended. User must establish a regular interval for maintenance as
determined by the user media and operational environment.
•Inspection should include visual checks of the sealing area, handle wear, missing
or loose components, leak tightness, ease of operation, sufficient lubrication,
wear, dirt accumulation and damage.
•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 a need for lubrication or other
maintenance.
•Use only original FasTest spare parts that are designed for the application and
are subject to strict quality control. See Warranty.
Safety Warnings – Guidelines:
•If instructions are not completely understood by operator or components are
missing, contact FasTest before attempting use of the connector.
•Application Safety: All FasTest products have been designed with safety in mind,
however, it is the responsibility of the products users to design each process in

Secondary restraints such as safety chains, shields, cages or fixtures are all good
choices depending on the application. FasTest can recommend or assist you in
clarifying potential hazards of your application.
•FasTest ZN Connectors are not internally valved, and will not prevent loss of
media when disconnected. Do not attempt to disconnect unless safe conditions
are met.
•FasTest ZN Connectors must only be used with test pieces of a specific size as
indicated by the part number. Improper use could cause separation of the

Installation:
Connect hose/fitting securely to the termination port of the connector.
1/8” NPT tighten to a maximum torque of 12 ft-lbs.
1/4” NPT tighten to a maximum torque of 25 ft-lbs
3/8” NPT tighten to a maximum torque of 40 ft-lbs
Operation:
Connecting Action:
1. Depending on the bore size the main seal(s) may need to be preloaded to
properly fit and seal the bore. To pre-load seals prior to insertion into bore
make sure handle is in line as shown in Fig 1, spin back cap in or out and
it will compress or de-compress the main seal(s).
2. Insert connector into bore and rotate handle, making sure a good seal is
made with test piece. If too loose or too tight in bore adjust back cap
again. If you can’t rotate handle then you’ve compressed main seal too
much.
3. Lock cap in place with lock ring.
4. Insert connector into port and rotate handle 90°degrees in either
direction. Main seal is compressed as handle is rotated.
•CAUTION NOTES;
•CAUTION: The maximum rated pressure is stamped on the connector body.
Before using, verify that this pressure rating is within your working pressures.
•WARNING: Tug on the connector to assure proper engagement and gripping
before introduction of pressurized media.
•DO NOT force connector onto test part when connecting. Forcing the connector
will result in poor sealing and possible leakage.
•DO NOT spin test piece on seal once lever has been rotated 90°degrees.
5. Activate test media through connector termination port.
Disconnecting Action:
1. Deactivate test pressure. (DO NOT ROTATE LEVER UNTIL TEST
PRESSURE HAS BEEN DEACTIVATED).
2. Rotate lever to the horizontal position and remove from test piece.
Pressure Ratings:
1.When testing smooth bore ports, maximum test pressure is 50psi.
