1. Lubricated nuts are standard.
2. May be used down to -254_C (-425_F) if manufacturing process includes Charpy impact test.
3. This minimum is due to thermal expansion differential between piston ring and cage at low temperatures.
4. Except 427_C (800_F) on oxidizing service.
5. Spring is used only with single PTFE V-ring packing; lantern ring replaces spring in o ther packings.
6. Except 371_C (700_F) on oxidizing service.
