Ensure correct fit for KL06880 duotight FFL fittings
Duotight fittings are an easy way to make leakproof seals quickly and reliably. The female flare fittings are a unique fitting that seals without the use of an o‐ring, washer or thread tape.
These flare fittings require a small amount of deformation in the tapered/flared profile so a specific amount of compression is achieved.
This instruction sheet will enable you to easily determine the correct level of seal compression without the need to tighten the fitting excessively.
Use a marker and mark both the FFL and MFL sides of the fitting.
Paying attention to the markings in step 2, tighten the duotight fitting with a shifter and rotate the fitting an additional 180 degrees so the two markings are on opposite sides.
Submerse the whole disconnect in a glass of water while the fitting is at 30psi and check for leaks/bubbles. If any bubbles are detected, repeat step 3 and rotate the fitting by another 90 °.
