Common Applications

The TFYKN-T16 is a G1/4 compression fitting for 16mm OD rigid tubing. The body and collar are machined brass with an electroplated finish; dual internal O-rings seal against the tube wall while the threaded collar is hand-tightened to clamp the tube in place. A second O-ring at the G1/4 thread seals against the host component without PTFE tape. It is designed for acrylic, PMMA and PETG hard tube only and will not seal on soft tubing or on 12mm or 14mm OD tube. Cleanly chamfer the inside and outside edge of the cut tube before insertion to protect the O-rings.

Frequently Asked Questions

Q: What tube does it fit?

A: 16mm outer diameter rigid tubing: acrylic, PMMA or PETG. It will not seal on 12mm or 14mm OD tube, or on soft tubing.

Q: What thread does it use?
