If necessary, conduct performance evaluation lest under Also, stees corrosion cracking may occur it used under corrosive emironment. Take note of usage configured or PCV PIPE CUPLĂ, neplace it with a new one after correctionistic When cleaning CUPLA, care must be taken not to use any material that will affect the seal and body materials. Acoly theated seats of male lasers on the same no leat.

If not, the O-rings will get damaged and cause leakage. (Applies to SP-V CUPLA seal materials: ) For the purpose of robering the inserson load on cornection and to powert O-ring hom damage, apply a lobricant that is suitable for the operational environment to the Plug • Do not use pipe sizes other than the suitable sizes. It will cause the sizes and the same started to the sizes of the sizes of the sizes of the current constructions that Construction in the construction of the construction in the CUPLA).
 We construction of the construction in the construction of the construction of the construction of the l When connected with the copper pipe, do not rotate the pipe. It will damage the packing and cause leakage. (Applies to PCV PIPE CUPLA) Put a designated dust cap on CUPLA after disconnection when there is a possibility of foreign matter such as diri siscking to the seal surface. (Applies to SP-V CUPLA) • When disconnected, store CUPLA with the lever in the 'Open' position. (Applies to PCV PIPE CUPLA) Ausol is a sub of class between the present search out of class loads of mailunction. (Apples to SP-V CUPLA) However, if you need to relieve residual pressure, please consul • Do not use CUPLA in areas or environment where dust such as sand or metal powder can get in to CUPLA. It will lead to mattunction or leakage • Do not let paint stick to CUPLA. It will cause mailunction or leakage. • Be careful not to put scratches or dents on CUPLA. Especially, scratches on the sealing parts will cause leakage Do not apply any artificial impact, bend or tension. It will cause loakage or damage
• Do not dop CUPLA. It will cause loakage or malting equipment will result in reduce
• sult in reduced lifetime Ensure that any copper residue or swart that has achered to the inside of CUPLA is removed after use. (Applies to PCV PIPE CUPLA) Use only as quick connect couplings for fluid pipelines. (It cannot be used as a swivel joint) (Applies to SP-V CUPLA) • Only use CUPLA in a combination with NITTO KOHKI coupling "CUPLA". (Applies to SP-V CUPLA) • Do not disassemble CUPLA. It will cause leakage or damage

Elactronic coating or Elactronic coating The sea material will lower • The duribility of CUPLA differs depending on the operating animorment and conditions (pressure and tamperature etc.). If necessary, conduct performance evaluation fissi un Also, stress corresion cracking may occur it used under corresive environment. Take note of usage conditions Do not exceed the recommended maximum forque when screwing in to the male or female thread of CUPLA for installation. It will cause damage Plant to see the seat of the seat of the seat of the seat of the seat of the seat of the seat of the plant take the pressured.

It will cause leakage • Always install a shut-off valve between the pressure source and CUPLA The use of ining siters is strongly assised and recommended. To prevent damage, the fluid should be clean before reaching CUPLA The sea on these stool is a strong of the sea is the continued.  O perfect such as sand or metal powder can get in to CUPLA. It will lead to mattunction or leakage.
 Be car • Do not apply any artificial impact, bend or tension. It will cause leakage or damage • Do not drop CUPLA. It will cause leakage or maltunction. • Connecting CUPLA directly to vibrating or impacting equipment will result in reduced lifetime • Use only as quick connect couplings for fluid pipelines. (It cannet be used as a swivel joint)
