Common Applications
TWT90KND-K12 and TWT90KND-K14 are brass G1/4 90-degree rotary multi-link fittings that terminate a rigid tube and bend the line 90 degrees in a single body, removing the need for a separate compression fitting plus elbow. The K12 variant accepts OD12mm rigid tube; the K14 variant accepts OD14mm rigid tube (acrylic, PETG, or thin-wall copper). A 360-degree rotary joint between the tube collar and the male G1/4 thread lets the elbow orient in any direction after install. Each fitting ships with internal O-rings and an outer compression collar that seals the tube against a fixed inner barb. Finishes available include black, silver, white, and gold.
Frequently Asked Questions
Q: Which tube OD does each suffix map to?
A: -K12 fits OD12mm rigid tube; -K14 fits OD14mm rigid tube. The inner barb is sized for each OD, so the two parts are not interchangeable.
Q: How does it seal against the tube?
A: The tube slides over an internal fixed barb with two O-rings and is locked by an outer threaded compression collar. Tighten the collar by hand until firm, then a final quarter turn.
Q: How far can the 90-degree joint rotate?
A: The rotary base spins a full 360 degrees relative to the G1/4 male thread, so the elbow can be aimed in any direction after the male thread is seated.
Q: Does this work with copper hard tube?
A: Yes, with standard OD12 or OD14 thin-wall copper or stainless rigid tube cut square and deburred. Acrylic and PETG must also be cut clean for the O-rings to seal.
Q: What is in the package?
A: One fitting body with inner barb, outer compression collar, and pre-installed O-rings. Tubing is sold separately.
