6. Technical Data
The gas hose assembles are intended to operate at 4 bar (though they meet the
specification to operate up to 56 bar @ 23°C) and are capable of delivering a flow
of 40+ LPM (highest range Oxylitre Flowmeter gauge reading is 15 LPM).
Vacuum: ≤ 60kPa
Spare parts will depend on the particular hose assembly variant (again please
contact our sales office).
Fittings are permanently crimped on.
Ensure that all connections are tightened and free of leaks prior to use. Use only
an Oxygen-safe leak detector when testing for leaks.
Note: Phthalates are used in the manufacture of the flexible hose and packaging
is labelled up as such to conform to BS EN 15986:2011 requirements (REACH
details are available on request).

AH Hose Assemblies
Operating & Safety Instructions
4. Servicing & Preventative Maintenance
The Oxylitre AH Series of Hose Assemblies have been designed specifically for most
types of Medical Gas supply services and comply with BS EN 5359:2014 and
European Directive 93/42/EEC.
Hose assemblies should be regularly inspected, cleaned and stored. It is important to
inspect the condition of the hose tubing itself for any damage, as well as for any
damage to probes, ferrules, outlets and terminal units. A regular inspection is
recommended as part of a maintenance programme. However, if the hose assembly is
attached to a mobile device such as a ventilator, where it could be dragged around,
then it is recommended it be checked prior to use.
All hoses are colour coded according to British Standard and have gas specific fittings
crimped to each end. Where the fitting are probes, NIST, DISS or terminals, the
products comply with BS 5682:2015, BS EN 15908:2010, CGA V-5:2008 and BS EN
ISO 9170-1: 2008 respectively.
It is recommended that the hose assembly should be inspected and pressure tested by
a Service Engineer on an annual basis as part of a maintenance programme.
Fully qualified technicians/engineers only should carry out servicing. For service
enquiries and information, please contact our sales office. NEVER USE FAULTY
EQUIPMENT. If in doubt do not use assembly, and obtain a replacement.
Preventative maintenance ensures the safely of the patient and user .
Each assembly carries a 5 year manufacturers’ warranty.
†Longitudinal coloured stripes.
It is recommended that the full hose section of an assembly be replaced after 5 years
service (in line with MDA/2003/007); this has the potential to extend operating life of
the full assembly up to 10 years with regular servicing.
Hose assemblies are marked with manufacturing details of actual hose and carry
details of date of assembly, serial number and additional product information.
*Assemblies also have white sleeving (other sleeves match hose colour).
2. Safety Warning: Safety precaution for prevention of fire & explosion
Ensure that hoses are not allowed near any heat or ignition source, this is especially
important where the product supplies Oxygen.
Hose assemblies MUST NOT come into contact with any oil or grease for the same
When not in use, hose assemblies should be stored in a clean and dry environment
within a temperature range of -10 to 40°C.
The hose assemblies require cleaning on external surfaces only by using a solution of
luke-warm water and a mild detergent/disinfectant (read manufacturers instructions)
and cleaning cloth. DO NOT autoclave.
Dry immediately with a dry cloth.
It is recommended that the assemblies are cleaned on a regular basis as part of a PPM
Avoid cleaning fluid from entering into any assembly orifices i.e. probes, outlets etc.
DO NOT use any oil based cleaning fluids (note: soaps can be oil based).
3. Instructions for use
On removal from packaging ensure that there is no damage to the assembly. Connect
the hose fitting to the appropriate device or gas outlet/inlet. As indicated the fittings
are gas specific and should only be connected to the correct source. It is the
responsibility of the end user to ensure that the correct assembly is used for the
purpose intended. Only persons with adequate training should use the hose
assemblies, noting the large number of possible variants of hose and fittings available.
