All of our EMB® couplings are supplied with the DS cutting ring as standard, we can supply the DSW cutting ring that has additional soft seal functionality if required.
Features of the DS cutting ring:
- The DS ring has two cutting edges; these however do not cut into the tube simultaneously, but one after the other, through which an improved cutting and sealing effect is achieved.
- The first cutting edge provides a secure joint and seal between the tube and coupling body whilst the second improves further the fitting integrity under the most arduous of conditions and provides a “physical stop” to prevent over assembly.
- In addition to the two cutting edges that support the tube during assembly the central body of the ring also provides this function and ensures that assembly force is distributed throughout it’s length.
- This design ensures that an increased assembly force is imparted over the total length of the ring from the cone of the tube nut culminating within the body of the fitting. The highly finished surface of the ring provides minimal opportunities for friction to reduce the sealing effect.
- Besides increased stability the design of the DS ring reduces stress on the nut, ensuring greater effectiveness and the reduction of the cross section optimises radial stability and increases tube security.
- The Stop area prevents over tightening of the assembly by producing a perceptible increase in force required.
