Specifications to Be Checked When Selecting Cuplas Fluid and the Temperature Having checked the type and materials for the Cupla, now specify the size and type of end configurations to suit the type of piping. Choose carefully, as the size affects the fluid flow rate. There are different body and seal materials to suit different fluids. For example, we recommend steel for air, and brass or stainless steel for water. Fluid pressure is also a key to Cupla selection. Each Cupla has a different structure to cope with each pressure resistance range. Valve combinations are two-way shut-off, one-way...

Models and Dimensions (waf : WAF stands for width across flats.) Application Example The photo shows connection of the 3S-V-W and 3P-V. Double O-ring Version of SP-V Cupla sp-v cupla S-V-W Type Employs a double O-ring sealing structure to suit high airtightness. Highly effective in airtightness and vacuum resistance when connected! Specifications The same specifications as the SP-V Cupla. See the SP-V Cupla specifications. Note: No lubricant is applied to HNBR O-ring in the socket. Please apply refrigerant oil to O-ring before use.

SP-V-GN Cupla Prevents an operator from mixing up different refrigerants. It may cause damage to equipment or products if different refrigeration oils are mixed together. • There is no interchangeability between SP-V Cupla and SP-V-GN Cupla to prevent accidental misconnection. • A socket of SP-V-GN Cupla has a different shape from that of SP-V Cupla and has a groove on the body. A plug of SP-V-GN Cupla also has a groove on the Nut to be distinguished from SP-V Cupla. Comparison of External Appearance SP-V Cupla SP-V-GN Cupla SP-V-GNN Cupla CUPLA X indicates non-interchangeability. Specifications...

Models and Dimensions (waf : WAF stands for width across flats.) Socket Plug Detailed Comparison of the SP-V and SP-V-GN Plugs Interchangeability SP-V-GNN Cupla When a plug of SP-V type is inserted into a socket of SP-V-GN type A plug of SP-V type cannot be inserted any further into a socket of SP-V-GN type as shown in the figure to the left due to the outer diameter of the plug, where the surface is sealed by O-ring, being larger than the inner diameter of the socket. Therefore, the plug and socket cannot be connected and the shut-off valves in both Cuplas do not open. When a plug of SP-V-GN...

For Connection to Copper Pipes PCV Pipe Cupla Clamps directly on a straight copper pipe eliminating unnecessary welding or flaring. Double seal construction withstands a vacuum of up to 1.3 x 10-1 Pa. Suits for refrigerants that require high pressure. • Withstands a vacuum of up to 1.3 x 10'1 Pa {1 x 10'3 mmHg} (when connected) making it possible to be used in leak test, vacuum suction and refrigerant charge. • Select from three standard types of seal materials to be used with fluids for air conditioner and refrigerator production lines. Many models to suit various pipe sizes. • One lever operation...
