PRODUCT SPECIFICATIONS

Series: AS568-145
Inside Diameter: 2-9/16 Inch
Width: 3/32 Inch
Outside Diameter: 2-3/4 Inch
Material: 90 Viton BISPH Black

DESIGN SPECIFICATIONS

According to DIN ISO 3601
Endless, circular ring with circular cross-section
Material: EPDM, FKM, HNBR, NBR, PTFE, VMQ

FUNCTION

Sealing effect due to cross-sectional deformation after installation and axial or radial compression in the installation space
In the operating state, media pressure reinforces the sealing function

PRODUCT ADVANTAGES

Universally applicable
Reliable design with broad application spectrum for moderately demanding applications in general industry
Good price/performance ratio
Manufactured by certified external suppliers

COMMON APPLICATIONS

Dynamic sealing of reciprocal, rotating and superimposed screw movements
Static sealing of stationary machine and system parts against liquid and gaseous media (flange and cover seals, pipe fittings, cylinder head and base for hydraulic cylinders)
Sealing of pressures up to 1000 bar, use of support rings may be necessary

MEDIA RESISTANCE
NBR

Good chemical resistance to various mineral oil and greases (H, HL, HLP)
Flame-retardant hydraulic fluids HFA and HFB, HFC up to appr. +50°C
Water up to max. +60°C
Low resistance to ozone, weathering and ageing

FKM

Good chemical resistance to mineral oils and greases, synthetic oils and greases, engine, gearbox and ATF oils up to approx. +150 °C
Fuels, flame-retardant pressure fluids HFD, aliphatic, aromatic and chlorinated hydrocarbons
Water up to max. +60°C
Very good resistance to ozone, weathering and ageing

EPDM

Good resistance in superheated steam and water vapor<
Detergent, caustic soda and potassium hydroxide solutions
Silicone oils and greases
Many polar solvents and diluted acids
Good ozone resistance

HNBR

Heat, ozone and ageing resistance significantly better than NBR

VMQ

Water up to max. +100°C
Aliphatic engine and gear oils, animal and vegetable oils and greases

PTFE

Good chemical resistance to aggressive acids, bases, alcohols or oils

Very good resistance in a wide range of mediaDESIGN GUIDELINE

Dimensions of installation spaces depend on cord thickness used and respective applications
Depending on ring thickness and application, groove dimensions result in an average compression of 15 to 13%
With pulsating pressures, hardness of the o-ring should not be less than 80 Shore A

INSTALLATION GUIDELINE

Deburr sharp edges, provide with seamless chamfers and radii
Clean the installation space carefully before installation, remove dust, dirt, metal chips, etc.
Do not pull the seal over sharp edges, threaded tips or cavities (feather key grooves) during installation, cover with a mounting sleeve if necessary
Heating the seal in oil at 80°C makes the sealing material more elastic and the seal is easier to install
Grease mounting surfaces and seal
Grease the elastomer sealing element before assembly to improve the dynamic coefficient of friction and thus ensure a longer service life
Do not roll the O-ring over the mounting surfaces, do not twist it when snapping into the groove
Do not expand the seal to the expansion limit

STORAGE ADVISE

Storage temperature <25°C
No direct heat sources
No direct sunlight
No condensation in the storage room
No exposure to ozone or ionizing radiation
Recommendations based on the revision of ISO 2230 dated 16.09.1992
