R-1234yf**, R-1234ze**, R-125, R-134a, R-290**, R-32**, R-404A, R-407A, R-407C, R-407F, R-407H, R-410A, R-417A, R-421A, R-422B, R-422D, R-427A, R-438A, R-444A**, R-447A**, R-447B**, R-448A, R-449A, R-450A, R-452A, R-452B**, R-452C, R-454A**, R-454B**, R-454C**, R-457A**, R-459A**, R-507A, R-513A, R-513B, R-600A**, R-718 and HYCOOL 20. |
*Please refer to >B< MaxiPro - Tube Compatibility Tables, see section 12.10. |
** When using refrigerants classified A2L (lower flammability), A2 (flammable) and A3 (higher flammability) additional/specific standards, local rules and regulations, codes of practice and by-laws may be applicable. Note: >B< MaxiPro fittings are NOT suitable for R-717, R-723, R-764, R-744 refrigerants. |
3 - Point Press:
>B< MaxiPro benefits from a 3-point press; one each side of the bead, and one press 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 3 times faster to install than brazing.
