The M4 is a reel with four hydraulic lines in two twin hoses, with two independent external springs. Ten sizes offer 3.2 to 26.5 m usable length depending on diameter and part number, with a maximum flow rate of 40 l/min. This design alone does not guarantee service life or operating frequency.
M4D: right-hand; M4S: left-hand. Keep the size, diameter code and hose type XX; photograph the mounting and both assemblies to be replaced.

Specify the travel and constraints of both hose assemblies for validation. The drawing shows 4 × 3/8″ or 4 × 1/2″ and a flange with Ø 11 mm holes, 60 mm square centres and 80 mm overall size. Request the PDF/STEP drawings for the selected configuration.
The permissible pressure of the supplied assembly must respect the limits of the reel, hose and connections. Specify the fluid, its temperature, the flow rate and working pressure to validate the equipped part number; the pressure rating of the reel alone does not guarantee that of every hose combination.
TU2 catalogue reference data: pressure ratings of the hose alone, in bar. These values are not the guaranteed pressure rating of the equipped reel. The final configuration must respect the limits of all its components; the table below does not establish that every combination is available in every size.

|---|---|---|
| 1/4″ | R7 | 210 |
| 1/4″ | B1 | 310 |

To replace a reel, send the full part number and a photograph of the nameplate, mounting details, right/left-hand version, working position, fittings and usable length. Request the manual for the exact version before installation or servicing.
Compare the A4 for two twin hoses and the S4 for four separate hoses. The catalogue confirms two independent external springs on the M4, but gives no cycle-life classification to justify an automatic recommendation for intensive duty. See the DEMAC technical catalogues.



Tell us the number of lines, hose diameter, working pressure and flow rate, usable length and the machine to be equipped.
