DIN 2353 cutting rings
The cutting ring is the component driven onto the tube during assembly of a DIN 2353 bite-type connection. Select a ring matched to the tube size, series, material and supplied fitting system.
Supplied by Fluidline, Midrand, South Africa. Delivery enquiries welcome across Southern and Central Africa.
