Catalog 4400 US
Numerals
1. For air or gaseous applications above 250 PSI (1,7 MPa), the
cover should be pin pricked. The service life for air or gaseous
applications can be unpredictable, especially at higher pressures.
Contact Technical Service Department for more information.
2. Legal and insurance regulations must be considered. Contact
Technical Service Department for more information.
3. Push-Lok hoses 801 and 836 are approved for diesel fuel
applications only when coupled with HY series fttings.
4. Use 285, 235 or 244 hoses. The compatibility of the systems
refrigeration oil with these hoses needs to be evaluated on
a case by case basis. Contact HPD Technical Service
Department for more information. Do not use mineral oil or Alkyl
Benzene refrigeration oils with 244 hose. Chemical compatibility
does not imply low permeation.
5. 150°F (65°C) maximum.
6. Satisfactory at some concentrations and temperatures,
unsatisfactory at others.
7. For phosphate ester fuids use 304, 424, 774, F42 or 804 hoses.
8. Acceptable for fushing hose assemblies.
9. 221FR hose recommended.
10. For dry air applications, hoses with inner tubes from columns IV,
and V are preferred. See hose specifcations for maximum
recommended temperatures with air.
11. Use SS23CG or SS25UL
12. Use SS23CG

Caution:
The fuid manufacturer’s recommended maximum operating temperature
for any specifc name-brand fuid should be closely observed by the user.
Specifc name brand fuids can vary greatly between manufacturers
even though they are considered to be from the same family or type of
fuids. Using fuids above the manufacturers maximum recommended
temperature can cause the fuid to break down, creating by-products
that can be harmful to elastomers or other materials used in the
system. When selecting a hose type, both the fuid manufacturer and
hose manufacturers maximum temperature limit must be taken into
consideration, with the lower of the two taking precedence.

Warning
:
This chemical compatibility guide must not be used in
conjunction with any other compatibility guides from previous or future
catalog editions, bulletins or publications. Incorrect use of these charts
could result in death, personal injury or property damage.
Hose Selection by Medium and Hose Type
This hose compatibility chart is a ready reference of Parker hose
compatibility with various fuid media. It is intended as a guide to
chemical compatibility with inner tube materials and assembly lubricant
applied internally. The specifc recommendations are based upon feld
experience, the advice of various polymer or fuid suppliers, and specifc
laboratory experiments.
It must be stressed, however, that this
information is offered only as a guide.
Final hose selection depends
also upon pressure, fuid temperature, ambient temperature, and
special requirements or variations, which may not be known by Parker
Hannifn. Legal and other regulations must be followed with particular
care. Where an external compatibility problem may occur, or for fuids
not listed, we encourage you to frst contact the fuid manufacturer
for a recommendation prior to contacting your Parker Hannifn Field
Representative or the Technical Service Department, Hose Products
Division, Wickliffe, Ohio.
Use the Chart as Follows:
1. Locate medium to be carried using the Chemical Resistance
Table on the following pages.
2. Select suitability of hose and ftting material from the table based
on the letter rating in the table. See resistance rating key below
for explanation of compatibility ratings. See list of numerals
below for an explanation when a numeral, or a numeral and a
letter rating are present in the table.
3. The Column headings on the Chemical Resistance Table, I, II, III,
IV, V, refer to specifc groups of hoses.
4. Locate hose part number under Column l, ll, III, IV, V from the list
below.
5. For ftting material availability refer to appropriate ftting section
of catalog.
6. Check hose specifcations in this catalog. Contact Hose Division
Technical Service Department on any items not cataloged.
Resistance Rating Key
A = Preferred, good to excellent with little or no change in physical
properties.
F = Fair, marginal or conditional with noticeable affects on physical
properties.
X = Unsuitable, severe affects on physical properties.
~ = No rating, insuffcient information.
Note: All data based on 70
°
F unless otherwise noted.
