Specifications
Flame-free: Flame-free installation avoids the need for a hot work permit and the risk of fire on site.
No nitrogen purge: >B< MaxiPro is a mechanical joint, thus eliminating the need for nitrogen purge during the jointing process
Lower installed cost: A professional fitting which is quick and simple to install, saving time and money.
Higher productivity, improved flexibility: Work may be completed during working hours / public access, by a single employee.
Site access: Easy access to work sites, no gas bottles required.
Quality designed in: Reliable, repeatable, permanent, tamper-proof connections every time.
3-point press: Three press points, one each side of the bead, and one press compressing the O-ring. This provides a permanent and secure joint.
High quality O-ring: A high quality HNBR O-ring forms a secure leak-free joint when pressed.
Protected O-ring: Lead-in edge design aids tube insertion and helps protect the O-ring from damage or displacement.
Fitting identification: Fittings are marked >B< MaxiPro and identified with a pink mark indicating their suitability for high pressure air-conditioning and refrigeration applications.
Electrical continuity: Maintains earth continuity without the need for additional earth continuity straps.
Certification: >B< MaxiPro is UL listed, refrigerant fitting SA44668.* >B< MaxiPro is UL listed, approved use for field and factory installations.*
Field proven: Press-fit technology, field proven over 20 years and millions of installed fittings worldwide.
Guarantee: When professionally installed by a trained and certified >B< MaxiPro installer, >B< MaxiPro is covered by a five year extended guarantee.
Support: Backed by Conex Bänninger’s experienced technical support and customer services teams.
Compact tooling: Light compact tooling provides easy access to tightly spaced tube runs.
Tooling concept: We recommend using tried and tested ROTHENBERGER tools and jaws.
*Please refer to UL’s online certification database for full details of listings.
Note: When using the tool, wear ear and eye protection. Regular care and cleaning of the jaws can be completed by the user. Prior to use check the press jaws are free of damage or deformation and the inner pressing contour is free of dirt or debris.
>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.
In tests, press fittings are up to three times faster to install than brazing.
