Assembly
Assembly procedure:
1. Cut appropriate length of tubing and remove burrs..
2. Installation sequence:
- Position the socket, stopper ring and graphite conical sealing.
- Note that the graphite conical sealing and the tube end must be at the same length
3. Tighten the nut.
4. Allow room for thermal length expansion.
5. Allow 20 cm tube length prior to fixing or bending.
