The body of elbow connectors and extended elbow connectors are compatible with
almost any fitting. (Except “L-04” and “LL-04” which are for the body of ø6 tube.) Swivel
fittings, elbow (L) and (LL) constitute the combination with a male connector (H) and
connector as shown in the diagram.

Precautions
Be sure to read before handling.
Refer to front matter 56 for Safety Instructions and pages 13 to 16
for Fittings and Tubing Precautions.
Installation
Caution
1. Cut the tube perpendicular to the tube axis a little longer than the required length. (Use
tube cutter TK-1, 2 or 3.)
2. Then, push the cut tube in until it comes to the flared edge, and tighten the nut by hand.
3. Furthermore, give the nut an additional 1.5 turns with a tightening tool. Leave no space
between the screwed-in nut and the tube in-line with the tube axis. If tightened
insufficiently, nut may be loosened and it may result in air leakage or may come off.
