定義
快速緊固接頭是一種裝置，使管道與管道連接具有良好的水密封性；或者是管道和零部件之間的連接密封性，此裝置無須使用額外的零件，以及具有免維護性。
相應于應用的條件，此種連接可以有固定的目標體，也可以沒有。
連接由一個雌頭件和一個水龍頭組成，請參見章節1.3.
此耦合連接對于那些系統內有特別要求的部分而言是一個示范，請參見章節1.4.
一般而言，雌接頭件套接在橡膠管道上面，水龍頭則安裝在所應用的零件上（散熱器，熱交換器，波紋歧管等等。）
活栓供應商和雌接頭供應商不允許是同一個單位，兩個零件都必須達到一致性測試的要求。
1.2
緊固耦合件/管道間的接觸
每一種接觸類型/技術方案（比如：連接形狀、管道材料的類型）都必須符合指定的應用場合/零件采購規格說明。
每個集合件都必須符合相應的管道采購規格說明內所指定的類型。

緊固耦合連接無須任何形式的潤滑。
 O形密封圈須由供應商提前作好潤滑步驟。此類條件下，為了作好資質控制以及相應的修正方案，潤滑參數必須提交給中心實驗室，并且需要同時附上最大使用數量參數。
  配孔內的插入件（也包括那些同心度有偏差的零件）不得損傷O形密封圈，也不允許損傷配孔本身，在正常的重復操作條件下不應該影響密封的效果。

  備注：車輛/馬達生產線上的連接裝配程序中所使用的所有的工具，包括全自動的、半自動的、手動的，都必須事先得到供應商的核實。此類供應商是指那些提供相應的管道件/零

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.
