PCV CUPLA |
■ Straight pipe couplesr specially designed for pressure test, vacuum evacuation, and freon charging.
■ Possible connection and disconnection without welding or flaring pipes.
■ Can withstand a 10-3mmHg degree of vacuum and is most suitable for freon (R12,22) and refrigeration oil.
■ Packings are also selectable according to type of fluuid. |

Feature |
- Pipe chuck system for fixing outside of a pipe uniformly is used for safety.
- A copper pipe is sealed by a packing for sealing the pipe and by a special X ring for sealing the periphery of pipe to provide an excellent seal and vacuum resistance.
- At insertion, no pipe comes in contact with the outer seal (X ring) to prevent rubber deterioration.
- A single lever operation allows a pipe to be chucked and sealed at the same time.
- Easy maintenance. The packing, X ring and chuck can be replaced just with a screwdriver.

Operation and Structure |
When connecting |
Pull up clamp lever at least 90°and insert pipe until it meets the packing.
Push down clamp lever.
When chucked, the pipe is drawm in an additiona; 0.5mm and the end is sealed. (Using excessive force when inserting pipe may shorten the life of the packing seal.) |
When disconnecting |
|
Pull clamp lever up at least 90°.
Pipe disconnects easily. |
Precaution |
- Pipe CUPLA sizes are according to outer diameter of pipe.
- Consult us when using a pipe with thin walls.
- Make sure pipe is free of burrs or deformation. Chamfer the pipe end.
- Use vise to hold hexagonal part of socket adapter when connecting SP-V plug set.
- Do not connect/disconnect while there is pressure in the line.
- After using, disconnect pipe and leave clamp lever in up position for storage.
- The packing, X-ring, and chuck eventually wear down and should be replaced after the CUPLA has been connected/disconnected approx. 5,000 times.
