O-ring will not drop off during connection

Since the O-ring is attached beforehand, it will not drop off during connection like conventional fittings.

 

Installation of O-ring

Safety Lock function

As a safety measure, the "Safety lock" feature ensures that there can be no unintentional disconnection of CUPLA. By turning the cam handle, you can maintain the connected state of the socket and plug.

Seal part (cross section)

Because of the structure of this product, dead space is generated when using.

Connection and disconnection of socket and plug is enabled by sliding either the socket or plug to the central axis of pipe. When connecting the couplers to the pipe, ensure that there is at least minimum moving distance (L) in the axial direction.

Precautions to be taken when using CUPLA

Precautions to be taken when using CUPLAQm.png

・Any residual fluid remaining in the passage will spill out on disconnection. Drain any residual fluid before disconnection to avoid burns or injury to the skin when dangerous fluid such as chemical agent or high temperature fluid is used.
・There is a dead space in CUPLA. Be careful that this may lead to the spread of bacteria.
・CUPLA can be easily disassembled for cleaning. CUPLA should be evaluated before use to determine the suitability with regard to sanitation and safety. Especially when using O-rings of other brands than Nitto Kohki, be sure to evaluate the O-ring at your end.
・Do not use CUPLA continuously under any pressure exceeding the rated working pressure.This may cause leakage or damage.
・Use only within range of its rated temperature. May cause damage or deterioration to the sealing and leak if used otherwise. Also, do not use continuously at the lowest or highest working temperature.
・The durability of CUPLA differs depending on the operating environment and conditions (pressure and temperature etc.). If necessary, conduct performance evaluation test under your actual operating environment and conditions.
・Connection and disconnection of socket and plug is enabled by sliding either the socket or plug to the central axis of pipe. When connecting the couplers to the pipe, ensure that there is at least minimum moving distance in the axial direction.
・The outer diameter and thickness of the pipe to be welded to CUPLA must conform to JIS G 3447.
・Malfunction caused by welding (directly or otherwise) is not included in the warranty.
・When powder is applied to CUPLA, static electricity may be generated. Please take countermeasure against this if required.
・When CUPLA remains connected for long periods of time, it may become difficult to disassemble.
In this case, do not forcefully turn the socket and plug to disconnect as this may damage the seal material and cause leakage.
・The O-ring and Lock plate ASSY are consumable items.
・See the following list as a replacement guide for the Lock plate ASSY.
・When the Lock plate ASSY is deformed, replace it with a new one regardless of connection/disconnection times.
・The durability of the O-ring differs depending on the operating environment and conditions (pressure and temperature etc.).
・Be sure to read the "Instruction Sheet" that comes with the product before use.
