OPERATING INSTRUCTIONS

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 un­coupling 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.

Connector Operation:

1. Insert test piece into the end of the connector and secure.

2. Apply pilot pressure to seal against the part.

3. With pilot activated, introduce gas or liquid through the FasTest ME

4. Perform testing operation.

5. Relieve test pressure.

6. Relieve pilot pressure.

7. Remove test piece.

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

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.

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.

Installation of Seals ME001:

To Replace Seal

1. Unscrew and remove seal casing. W rench 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.

2. Main seal o-ring is held in the seal casing by friction fit. Remove old o-ring and
replace with a new one.

ME001 Connector Seal Range

Changing the seal casing assembly allows the user to have one ME001 body seal the
entire .030” to .130” sealing range. The MES Replacement Seal Sets are list on the parts
list. Installation is similar to the replacement seal installation except that the entire seal
casing assembly (seal casing and Viton o-ring) is replaced.

Connector Maintenance:

• A daily, weekly and periodic inspection of the connector by competent person is
recommended.

• Lubricate connector on regular intervals. Petroleum jelly is recommended but care
should be taken to verify the lubricant is compatible with the application.

• User must establish a regular interval for maintenance as determined by the user
media and operational environment.

• Inspection should include damage to the body missing or loose components, leak
tightness, ease of operation, sufficient lubrication, wear, dirt accumulation and
damage.

• Use only original FasTest spare parts that are designed for the application and are
subject to strict quality control. See warranty.

DESCRIPTION: Operation and Seal Installation

Please thoroughly read and understand each of the following four steps before
operating the connector. The use of pressurized media for sealing, testing and
filling requires a thorough understanding of the FasTest ME/ML Operating
Instructions.

1. Attachment of Pilot Pressure and Test Media Supply Lines

2. Mounting Dimensions of Connector

3. Connector Operating Instructions

4. Installation of Seals

• The connector is designed to mate with a specific application. Verify the application
prior to the introduction of pressure or processing.

• Use only in a safe environment.

• Connectors are NOT designed for permanent connections and are for temporary

connections only.

• Maximum rated test pressure for standard ME models is 500 psi. DO NOT EXCEED
pressure rating as marked on connector or corresponding literature. Consult your

FasTest representative with other requirements.

FasTest ME & ML Pneumatic Operated Connectors are designed for use

in SECURED CONDITIONS ONLY.
