The 108mm Collar set consisting of zb321 stage 1 adaptor, zb322 stage 2 adaptor and 108mm collar complete with case
The design of the jaws, collars and adapters means they can only be used with the matching pressing units. The reliability of the mapress pressfitting connections has been tested and certified with mapress pressing jaws and collars (including adapters) to DVGW Code of Practice W 534, DVGW Test Guidelines VP 614, ÖVGW G1-TR-GAS (Austria) and SVGW-W/TPW 132 (Switzerland). We have not tested other makes of pressing jaws for compatibility with the mapress pressfitting system.
The pressing profiles of the jaws and collars must be free from dirt and deposits. Clean with an agent such as methylated spirit. Follow the manufacturer’s operating instructions and service the pressing tools regularly. To avoid invalidating the warranty and ensure a reliable pressfitting connection, the pressing tools have to be regularly checked and maintained. This is described in detail in the operating instructions for the tools under Safety, Maintenance and Repairs. The customer receives a service record to certify that this work has been carried out, and an annual service sticker with the next service date is affixed to the pressing tools.
