Attachment of Pilot Pressure and Test Media Supply Line:
1. Attach pilot pressure air line to pilot port.
2. A pneumatic regulated source is required to maximize seal life and assure
optimum seal ability for the application. The pilot pressure should be minimized to
maintain sealing on the test piece without excessive compression of the seal.
3. Attach test media line to the test port.
4. Provide a means whereby test pressure will not be introduced until the pilot
pressure required to seal is reached. The means should also provide quick exhaust
of test pressure in the event pilot pressure falls below the minimum required to seal.
Mounting of Connector:
The ME Connector must be SECURED to the test piece by a mechanical device
before proceeding.
• The test connector must be secured with a mechanical or other device to assure the
connector is not uncoupled from the test piece. The test itself will provide an un-
coupling force. The securing or holding device may be a fixture, clamp, cylinder or
other appropriate means that prevents ejection of the test piece from the connector.
Uncoupling force example:
If the test piece has a ½” O.D. and is tested at 400 psi maximum. The uncoupling force = area(πr²) x
pressure) = π x .25² x 400 = 79 lbs.
• Secured device should be designed to withstand this force and include an adequate margin for
safety.
• Do not activate the connector without an adequate and safe securing mechanism.
• Mount the FasTest ME connector to the fixture or appropriate device using either threaded
mounting holes on the rear of the connector body, (“G” Diagram 2), or appropriate adapter.
ME/ML Connector Dimensions:
Maximum test pressure: Vacuum to 500 psi
Material Specifications
Body, Housing, Piston:
Aluminum
Standard Main Seal: FDA approved Viton
Standard O-Rings: FDA approved Viton
Other materials available on request.
NOTE: All specifications subject to change without notice.
Connector Operation:
1. Insert test piece into the end of the connector and secure.
Make sure the test piece is inserted to the required minimum insertion
length. This will assure proper location relative to the seal. Make sure
the connector and test piece are secure
2. Apply pilot pressure to seal against the part.
Generally, a 60 to 90 psi pneumatic pilot pressure source is required.
Additional pilot pressure may be required for contoured surfaces (i.e.,
threads etc…). See FasTest catalog for Pilot Pressure Booster.
CAUTION: Do not activate PILOT or TEST PRESSURE without test
piece in place.
3. With pilot activated, introduce gas or liquid through the FasTest ME
connector until desired testing, filling or flushing is complete.
Provide a means whereby test pressure will not be introduced until the
pilot pressure required to seal is reached. The means should also
provide quick exhaust of test pressure in the event pilot pressure falls
below the minimum required to seal.
4. Perform testing operation.
5. Relieve test pressure.
6. Relieve pilot pressure.
7. Remove test piece.
Installation of Seals ME001:
To Replace Seal
1. Unscrew and remove seal casing. Wrench flats provide for easy removal.
NOTE: The internal spring is set loose inside the housing. Make sure that this spring is
not damaged or lost.
