Bite type Fittings – JIS

Bite type fitting consists of three parts : Body , Sleeve and Nut, and is designed to work over medium and heavy wall tubing.

When tightening nut, sleeve driven forward on the tube then bites the tube with the edge of sleeve, this is how sealing is achieved and results in internal ridge inside the tube.

Bite type Fittings-DIN

Bite type Fittings – DIN

The DK DIN bite type tube fitting is a flareless metric fitting that consists of a body, a progressive ring (sleeve) and a nut. On assembly, two cutting edges of the progressive ring bite into the outer surface of the tube ensuring the holding for high tube pressure.

Available in three series, DK DIN bite type tube fittings and accessories are manufactured in accordance with DIN2353/DIN EN ISO8434-1. The fittings and components in this catalog are intended solely for the assembly of connections for fluid applications.
