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.) Socket Plug Detailed Comparison of the SP-V and SP-V-GN Plugs Interchangeability 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 type is inserted...
