Quick-Connect Fitting, KQ2 Series, Double Branch, KQ2UD (With Sealant / Without Sealant)

One-touch fitting double branch that drastically cuts piping work-hours with the gasket-seal method.
[Features]
・ Improved tube insertion and removal
・ Compact and weight reduced
·Can be used in vacuum to -100 kPa
·The chamfered part of the female thread is the sheet surface, and a gasket with NBR laminated on both sides of the stainless steel plate is used as the seal
·Structure that can be sealed regardless of the difference in diameter due to different types of female threads, variation due to tolerance, size of chamfer, etc.
·All normal chamfered female threads can be used
[Applications]
·Used for 4-branch piping in the same direction from the female thread

* Please refer to p. 131 for the made-to-order / clean series.
