GENERALITIES
1.1
Definition
The fast coupling is a device allowing a watertight connection between two pipes or between a pipe
and a component/user, without using further fastening components and without maintenance needs.
According to the application, the connection can require objectivation or not.
The connection consists of a female part and a tap, as shown in paragraph 1.3.
The coupling can assume the orientation required by specific needs of the system, in which it is
installed, as shown in paragraph 1.4.
Normally, the female part is butted on the rubber pipe and the tap obtained on the using components
(radiators, heat exchanger, manifolds, etc.).
Should the tap Supplier be different from the female component one, both parts shall guarantee the
compliance with conformity tests.
1.2
Fast coupling/pipe interfacing
Each interfacing typology/technical solution (e.g. interfacing union profile, pipe material type) shall be
qualification subject aimed to the specific Procurement Specifications of the supplied components, on
which couplings were installed.
Each assembly shall be qualified according to modes specified by the P.S. related to the pipe being
examined.

1.6
Qualification extension
Each fast coupling family/typology has to be qualified.
The Managing/Supervising Dept. of this P.S. has to evaluate any qualification extensions for the
variations of diameter, heading typology or connecting system.
1.7
Connection
Fast couplings have not to need lubrication by the monitoring operator.
O-Rings can be pre-lubricated by the Supplier. In this case, in qualification and modification case, the
lubricant specification has to be sent to Central Laboratories, also indicating the maximum used
quantity.
The insert, also incorrect (e.g. not co-axial) of the tap has not to cause damages of the O-Rings or of
the tap itself, affecting its sealing after repeating the operation correctly.
NOTE: Any tools for the vehicle/motor online connection, either automatic or semiautomatic or
manual, have to be previously authorized by the Supplier of the pipe / component /assembly,
on which the rapid coupling is installed.
Mission profile
The coupling lifetime is the same as the vehicle one: 10 years or 300.000 Km covered at 30 Km/h
average speed for overall 10.000 h circulation of the coolant.
The cooling liquid temperature may vary from -40 to 140°C (150°C peak for max. 20 min), while the
temperature inside the motor compartment can range from -40 to 110°C (130°C peak).
The connection and disconnection number in the vehicle life can be 30 at the most.
1.9
Storage
Fast couplings must be able to be kept, with no damaging of their characteristics/performances, for
one year in a warehouse whose maximum temperature is 40°C and minimum temperature is -20°C,
with relative humidity ranging from 50 to 70%.
Fast couplings must be able to bear a maximum continuous temperature of 85°C and a minimum
continuous temperature of -30°C for two months (handling in ship/container), they must be able to
bear their stay for two months in an environment with relative humidity of 90% and temperature of 2°C
with no damaging of their characteristics/performances, the exposure, for 2 months, in environment
with 90% relative humidity and 0 ± 2°C temperature.
