General

Whereas standard ChipShop connectors only accept soft-walled tubing, this set of connectors allows connecting any 1/16" OD rigid tubing to a ChipShop chip.

Suitable for rigid tubing (PTFE, PEEK, etc.) with an OD of 1/16" (1.6 mm). Manufactured in blue TPE, max. pressure of 3.2 bar with a 1/16" OD PEEK tubing.

Plugs to block unused ports are also available in our shop.
