DESIGN
SEALEXCEL has designed the Bite
Ring very carefully with proper
consideration having twin Biting
edges to have firm and safe gripping
on tubing to provide leak free
connection of tube and components
in fluid systems.
FUNCTION
As the Bite-Lok® Tube Fittings Nut
tightened, the Bite Ring moves
towards the surface of the tube and
the front Biting edge 'A' of the Bite
Ring starts Biting tube

TUBING SELECTION
We recommend stainless steel cold
drawn fully annealed seamless
tubing to DIN 17458 or equivalent
and provide tolerances to DIN 2391

E : After assembly, a visible collar fills space in front of first biting edge.
DESIGN :
SEALEXCEL has designed the Bite Ring very carefully with proper consideration having twin Biting edges to have firm and safe gripping on tubing to provide leak free connection of tube and components in fluid systems.

The important  function of the Bite Ring is to have controlled progressive bite of the ring into the tube due to a unique internal geometry of the Bite Ring.
FUNCTION
As the Bite-Lok® Tube Fittings Nut tightened, the Bite Ring moves towards the surface of the tube and the front Biting edge 'A' of the Bite Ring starts Biting tube, at the point where second Biting edge 'B' of the Bite Ring comes in contact with the surface of the tube a sharp increase in torque will occur,  as soon as the both Biting edges have Bite the tube to the designed depth, the third stop edge 'C' of the Bite Ring comes in contact with the surface of the tube, a considerable increase in tightening torque which is already perceptible, at the same time, the Bite Ring is gripped firmly on tube providing perfect sealing.

Due to the design of twin biting and stop edges of the Bite Ring,  the arising force are properly distributed. This distribution with inner edge 'D' of the Bite Ring increase the safety with regard to flexure stresses. Thus the vibration is eliminated form the biting area.


This ensures
·  High degree of sealing efficiency
·  Reliable for high pressure applications
·  Vibration resistance
·  High Fatigue strength
·  Operational safety.
