The pressing profiles of the jaws and collars exactly match the pressfitting geometry. The pressing tools consist of a pressing unit and matching jaws or collars including adapters. There are different types of pressing unit to meet the requirements of each particular application.

The different designs are categorised in terms of the method of actuation:

Electromechanical Pressing Units
Models: EFP 2 and ECO 1 (ODs from 12 to 54mm) ECO 3 (ODs from 12 to 108mm)

Cordless Electromechanical Pressing Units
Models: ACO 1 and ACO 3 (ODs from 12 to 54mm)

Electrohydraulic Pressing Unit
Model: HCPS (Super Size) (ODs from 76.1 to 108mm)

Manual Pressing Unit
Model: MPF 2 (ODs from 12 to 54mm)

Pneumatic Pressing Unit
Model: PFP 2 – Ex (ODs from 12 to 54mm)

Pressing Jaws and Collars
Each pressing unit has matching quickchange jaws and collars for the different pipe ODs.

- Jaws - ODs from 12 to 35mm

- Jaws (lemon-shaped pressing profile for special industrial applications) - OD = 28mm

- Collars with adapter (lemon-shaped pressing profile for special industrial applications) - OD = 35mm

- Collars with adapters - ODs from 42 to 108mm

- Collars with adapters - ODs from 42 to 108mm

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.

Compatibility of Pressing Units
In the interests of the trade, and at the suggestion of the ZVSHK (German Heating, Plumbing and Air Conditioning Federation), the models supplied by some leading pressing system manufacturers have been designed to ensure interchangeability.

The compatibility declaration lists the following mapress pressing units: MFP2, EFP2, ECO1 and ACO1
The design of the pressing units EFP3, ECO3, AFP3 and ACO3 means they may only be used for the mapress pressfitting system. To ensure the reliability of the mapress pressfitting system and avoid installation defects, we recommend staying within the system and only using its components.

Maintenance and Servicing of pressing tools
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.
