Hoses with wire braid reinforcement
Type 1SN MAN 330-2
Dimensions in mm
All pressure specifications are positive!
This standard differs from DIN EN 853 in relation to the additional requirements for the short-time
maximum temperature (MAN 330-1, Section 1), the inner and outer layers of the hose (Section 4.1), the
tests (Section 4.3) and identification (Section 5).

1 Scope and purpose
This standard contains dimensions and requirements as well as specifications for the ordering and
identification of hoses with one wire braid reinforcement inlay Type 1SN, which, except for external
diameter d 2 and wall thickness s3, conform to hose type 1ST in accordance with MAN 330-1. These
hoses with thinner outer layer can be reinforced without the outer layer or part thereof being removed.
2 Release conditions
All parts of the standard series MAN 239 apply to release of hoses in accordance with this standard. In
these standards the release conditions and procedures as well as the general terms of delivery for
purchased parts are laid down.
The MAN department EPTA at the Nuremberg works is responsible for the material inspection, material
release and for providing information.
3 Dimensions, designation, pressures
The dimensions for d 1 , d 3 and r as well as the pressures correspond to those of the 1ST hose in
MAN 330-1.
The other dimensions are listed in Table 1 below.

5 Identification
5.1 Identification labelling
The hoses must be marked permanently and continuously at intervals of max. 500 mm as follows. Marking in
accordance with MAN 312-1.
Example marking: MAN 330 - 1SN - DN - ∆ - xxx - xQxx
Standard number
Hose type
Nominal diameter of hose
Manufacturer's trademark
Type identification designation of the manufacturer
Quarter and year of manufacture
If the hose cannot be marked with the MAN company standard number, the manufacturer's trademark and type
ID designation as well as the general standard number must be stated.
5.2 Material identification
The hoses are to be coded, when economically feasible, with the material codes for the inner and outer layer in
accordance with VDA 260. Content, carrying out marking and use of mandatory identification for MAN
components in accordance with MAN 312-1 or MAN 312-2.
