>B< MaxiPro technology:

3-point press:

>B< MaxiPro benefits from a 3-point press; one each side of the bead, and one press point compressing the O-ring. This provides a permanent and secure joint.

  1. Three press points, one each side of the bead and one press point compressing the O-ring.
  2. Tube stop.
  3. HNBR O-ring.
  4. Hook.
  5. Fitting socket.
  6. Bead.

In tests, press fittings are up to three times faster to install than brazing.
