Stainless steel (JIS SUS316L equivalent) for the liquid contact parts, buffing (#400) to prevent propagation of various bacteria (electro-plating available on request). Less deterioration due to excellent corrosion-proof material.

Versatile

There are two types of end configurations. Ferrule shape (ISO 2852 standard) and welding shape (JIS G 3447 standard).

Since the O-ring is attached beforehand, it will not drop off during connection. And the seal material conforms to article No. 3-D-3-(1) Rubber utensils (except nursing utensils) or Containers/Packages. It has passed both material and elution tests specified in the Food sanitation Act and the standards for Food and Food additives (Notice No.370 of 1959 issued by the Ministry of Health and Welfare of Japan). Also conforms to standard No. 21 CFR 177.2600 of the US Food and Drug Administration (FDA).

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.

・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.
