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.

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.

ME001 & ML001 Mini Connector
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.
