Non-spill couplings
DF2

Frequently asked questions
- What is the DF2 used for?
- For small fluid lines with 1/8" tubing that are disconnected often, for example when servicing dispensing or supply systems. The valves keep the fluid in the line while it is open.
- Why does a lubricant-free valve matter?
- No lubricant can migrate into the fluid, and the valve still seals reliably. Equipment and media stay clean.
- What do I need for one connection?
- One DF2 body and one matching DF2 insert. Both have a 1/8" hose barb and their own shutoff valve.
