GENERAL GUIDELINES
RULE NO. 1: NEVER MIX different manufacturers hose and fittings or other
            accessories. FAA (TSO) approvals are "as tested".

RULE NO. 2: There are FIVE (5) parts to every hose assembly; hose,
            two (2) end fittings, proper assembly processing or
            procedure(s), and proper tooling.

RULE NO. 3: Most hose assembly failures are a result of improper
            installation/handling, abuse, or old age.

                            HOSE FITTINGS

WHEN SELECTING A HOSE ASSEMBLY, BE
CERTAIN IT MEETS:
• Size requirements
• Pressure requirements, both operating and profile or application
• Temperature range
• Fluid compatibility
                                       2
TYPE APPROVAL
Each aerospace hose assembly has a specific type of approval that allows it to
be installed in an aircraft. Positive verification is required for proper inspection.

• Type Certificate (TC)
• Supplemental Type Certificate (STC)
• Technical Standard Order (TSO)
• Part Manufacturing Authority (PMA)
• Industry Standard (AN-AS-MS-NAS)
• Direct Ship Authority (DSA)
• Repaired Assembly (8130-3)



INSTALLATION AND CARE OF HOSE AND
HOSE ASSEMBLIES
General:
All hose assemblies whether rubber or PTFE, should always be handled with
care to prevent excessive bending, twisting, and kinking. Dragging hose on
ground surfaces, using them as climbing handles and severe bending to fit
cramped storage areas must be avoided. Kinking of hose occurs more easily in
larger sizes and in very short assemblies. Care should be exercised in handling
and installing both rubber and PTFE hose assemblies.

NEVER STEP ON, STAND ON, OR PULL HOSE.


Proper Storage:
Prior to installation, hose assemblies should be capped with appropriate dust
caps or plugs, properly identified (tagged) by part number, and stored in an
area free from dust or other contamination. Do not use cramped or otherwise
confined storage areas. If long lengths of PTFE hose are coiled for storage, a
liberal coil diameter must be provided to ensure against kinking. Never coil hose
so that the minimum bend radius(ii) can be exceeded. See AS1933 for more
information.


Inspection:
1. Inspect internally for evidence of tube restriction due to collapse, kinking,
   or other damage.
2. Inspect externally for wire damage. Assemblies with excessive wire
   damage should be replaced.
3. Proof pressure test all aerospace hose assemblies to required
   pressures. See applicable Drawing/Standard and Information
   Bulletin 1107.
                                                                     Continued on page 4

HOSE ASSEMBLIES     Continued from page 3


Chafe Protection:
Chafe guards of PTFE, vinyl, polyester, or other suitable material should be
used anytime there is a possibility of chafing. Chafing should be avoided by
routing of the hose assembly or by clamping.

Tips for Proper Installation:
1. Attach the hose to the most inaccessible end of its routing first. Finger
   tighten only, so the hose is free to turn during initial installation. Hose
   should not be twisted on final installation.
2. Attach the other end of the hose in the same manner.
3. Properly orient the hose along its routing and install the required line
   support clamps.
4. Use proper torque and remember to always lubricate! Use established
   installation torque values or consult ARP908 for limits. Also, the Flats
   From Finger Tight (F.F.F.T) method is simple to use and more
   consistent than measuring input force. Dissimilar materials or metals
   require different values (e.g. aluminum to stainless steel).

INSTALLATION AND CARE OF HOSE AND
HOSE ASSEMBLIES     Continued from page 4


When securing the line support clamps, exercise care in distributing hose slack
between the hose connections and the clamps. Do not bend or force the hose
to a sharp angle at any location. Be sure to use gradual curves for all routing.
Installation of clamps must never restrict travel or cause the hose line to be
subjected to tension, torsion, compression, or shear stress during flexing
cycles. Avoid installation of undersize hose support clamps. See AIR1569.

Position hose assemblies so the flexible portion of the hose extends at least
one times the hose diameter before starting a bend.

Always lubricate fitting threads prior to installation. Two wrenches may be used
to tighten end connections to prevent twisting of the hose or over-torquing of
fittings. Use one wrench to hold the nipple hex, if provided, while the other
wrench is used to tighten the swivel nut. On hose assemblies that do not
provide a hex for holding, use extra care to prevent twisting of hoses.

Small Bend Radius:
Many installations require a small bend radius. There are hose (assembly) types
specially designed and tested for these applications. Also, follow routing
guidelines presented here and in Wall Chart W-1 and AIR1569.

Identifying Hose and Hose Assemblies:
Before replacing a hose assembly, be sure to correctly identify it so the right
replacement can be made. Some hoses have a lay line on the cover that gives
identifying information. Hoses with a stainless steel outer braid are identified
with a white tape. The assembly is normally tagged as well.
                                                                Continued on page 6

INSTALLATION AND CARE OF HOSE AND
HOSE ASSEMBLIES     Continued from page 5


Typical lay lines are repeated every nine to ten inches along the length of the
hose and provides the following information:

• Manufacturer's Name and Manufacturer's Code.
• MIL-SPEC or Industry Spec Number.
• Part Number
• Dash Number (or code letter) for Size.
• Manufactured/Cure Date (if Rubber).




To prevent misapplication, do not use unmarked hose assemblies until
positively identified. Metal identification bands are often used to tag hose
assemblies with the part number(s), manufacturer, size, type, date of
manufacture and proof pressure tested. A log book entry is an acceptable
substitute as identification in lieu of a metal ID band for repaired hose
assemblies.

Which Hose to Use First:
To minimize aging effects of hose in storage, use the "first-in, first-out"
principle when selecting hose assemblies and bulk hose. Do not build rubber
hose assemblies for prolonged storage. Pressure test all assemblies before
installation. Do not install hose that has exceeded the established age limits
(four to eight years for rubber hose) or that show aging signs (separation of
plies, cracks, etc.) in aircraft. See Parker Stratoflex Information Bulletins 1050
and 1107.

HOW TO MEASURE AND SPECIFY DOUBLE
ELBOW FITTINGS ON A HOSE ASSEMBLY
Measuring:
When installations require hose assemblies with elbow fittings on both ends,
hold the assembly so the nearest fitting is pointed in the 6 o'clock position.
Measure the angle between the fittings counter-clockwise. When both fittings
point to 6 o'clock, this is specified as zero degrees.




Specifying Position:
Suffix the hose assembly part number with the number of degrees in the angle.
(Example: 111511E0185D180; 180 degree Twist Angle). See applicable
Catalog/Assembly Drawing for specific (hose) example.

Flow Capacities of Parker Hose at Recommended Flow Velocities
The nomogram below is provided as an aid determining the correct hose size.

Problem:
At 16 gallons per minute (gpm), what is the proper hose size for pressure lines?

Solution:
Locate 16 gallons per minute in the left-hand column and 20 feet per second in the right-hand
column (the maximum recommended velocity range for pressure lines). Lay a straight edge across
these two points. The inside diameter required is shown in the center column at or above the straight
edge. In this case, we need a hose I.D. of 0.625 (5/8) inch or larger.


         Flow
   Gallons per Minute
                                   The nomogram is based on the following formula:


                                 D=         Q X 0.4081            Where: Q = Flow in Gallons per minute (GPM

                          TEMPERATURE CONVERSIONS
 TO USE: Find the temperature to be converted (either Celsius or Fahrenheit) in the center column.
 If known temperature is Celsius, read the Fahrenheit conversion in the left column. If known
 temperature is Fahrenheit, read the Celsius conversion in the right column.
         EXAMPLE: 50.0 10 -12.2                                        °C = 5/9 (°F-32)
         10°C = 50°F 10°F = -12.2°C
