Flexible food-safe PTFE tubing. Cut to one (1) foot length (approximately 304.8 mm).
The product comes stock with "pipe" ends, meaning that it may be required to "flare" the ends of the tubing, depending on your make and model.
For the older Silva models (which use a 254 mm section), you will need to reuse your female compression nuts as these are no longer available as a separate item. The new version 3 Silvia models use the (HIGHLY recommended) R_702 stainless hose instead.
WARNING: This product can expose you to chemicals including lead, which are known to the State of California to cause cancer, birth defects, or other reproductive harm. For more information, go to www.p65warnings.ca.gov.
