DANGER This is Mandatory Rule!!
●Whenever using this product for hazardous chemical fluids or
solvents, wear anti-chemical protective gear (protective gloves,
protective mask, and protective clothing) that completely protects
your body. Exposure of chemical fluids may result in personal
injury.
WARNING
●Whenever connecting the connector, make sure that the paired female
thread used for it is NPT or PT and then use the appropriate male
thread. Using inappropriate male threads may result in personal injury
due to leakage of chemical fluids.
●Connecting the taper threads in the specified usage and procedures.
Connecting the taper threads in the wrong usage or procedures may
result in personal injury due to leakage of chemical fluids.
WARNING
●Do not damage the connecting part (wound with seal-tape) of plug and
socket. Damage of product may result in personal injury due to leakage
of chemical fluids.
●Do not contact the connector to any rigid materials because it is made
of resin materials. Damage of product caused by contact may result in
personal injury due to leakage of chemical fluids.

○Instructions on Maintenance and Inspection






●Release pressure from the piping before attaching/detaching the
connector. A pressurized condition may cause spouting of
chemicals, resulting in personal injury.
●Always wear anti-chemical protective gear (protective gloves,
protective mask, and protective clothing) that protects your entire
body when attaching/detaching the connector. A contact with
chemicals may cause personal injury.
●Attach/detach the connector in a clean place with no dust.
Degradation of sealing performance due to adhesion of dust may
cause liquid leakage, resulting in personal injury.
●Always attach/detach the connector at right angle to the surface of
container. Attaching/detaching the connector at an angle may
cause spouting of chemicals, resulting in personal injury.
●Do not apply the connector to rotary joint or other rotary
application. Lower tackiness caused by the wrong application may
result in personal injury due to leakage of chemical fluids.
●When the connector is connected, make sure that the connector is
fully connected. The chemicals may splash and personal injury
may be caused.
●Use out of the operating pressure range may result in slip-off. Be
sure to use within the operating pressure range.
DANGER This is Mandatory Rule!!
●Surpass Industry is not be liable to any failure or leakage of the product
due to O-Ring replacement and/or disassembly performed by any
parties other than Surpass Industry.
●When you need maintenance work, please call Surpass Industry.
CAUTION
・Apply operating fluid or pure water to the O-Ring of the socket
(inner) or O-Ring sliding part of the plug (sealing part) when
connecting the socket or plug to prevent the O-Ring from being
damaged and to reduce the slide resistance (insertion load).
・Do not use abrasive compound or fluid that is easy to clot as
they may impair normal function.

1. Description
Fluoropolymers Quick Connector Series are the "one-touch" (instant lock)
typed connectors for high-purity chemicals used in semi-conductor
manufacturing process. These connectors have proven their reliability and
convenience over many years. Also, repeated efforts to improve
chemical-resistance, leak-resistance, and particle reduction for higher
quality allow our connectors to be applied to various type chemicals.
