*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.
