SEAL REPLACEMENT INSTRUCTIONS

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 such a way to avoid
mishaps that can cause physical hazard or property loss. 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 ZGX 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 ZGX 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
connector from the test piece resulting in physical harm or damage.
