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
