Standard Type

Lip Style O.D. Style		S	T	V	K
Lip Style O.D. Style		General non-pressure fluid sealing applications and severe grease sealing conditions.	General non-pressure fluid sealing applications and severe grease sealing conditions with light duty exclusion of foreign materials.	Economical design for grease retention or sealing viscous fluid.	Economical design for grease retention or sealing viscous fluid with light duty exclusion of foreign materials.
A	Metal O.D. design with an inner case for greater structural rigidity
B	Metal O.D. design with fluid side rubber covered.
C	Rubber O.D. design for excellent O.D. sealing ability.
G	Corrugated rubber O.D. for large thermal expansion housing
B2	Precision ground O.D. surface with\a lead-in chamfer for ease of installation.
BC	Benefit of metal O.D and rubber O.D.
BG	Benefit of metal O.D. and corrugated rubber O.D.
BZ	Precision ground O.D. and a rubber covered top face for greater O.D. sealing ability.
CA	Rubber O.D. design with an inner case for greater structural rigidity

Non-standard Type

FYC TYPE	DESIGN CHARACTERISTICS	SEAL TYPE
3	The cavity will allow pre-lubrication of the seal to combat initial dry running or where space is limited and a secondary lip for dust exclusion is required.
P	Similar to the “3” type, but with a large cavity to pre-lubrication of the seal to combat initial dry running or where space is limited and a secondary lip for dust exclusion is required.
5	Rubber O.D. and metal O.D. with flange will allow easy installation or replacement, give additional structural rigidity and restricts the installation depth into the housing.
6	The secondary lip helps to prevent from dust.
9	The “9” type has the ability to act as a rotary shaft and an axial face seal.
K	Where dirt and dust ingestion is a problem, The "TCK" design provides superior exclusion.
VK	Designed for static applications to act as a plug or barrier
D	The “D” type seal incorporate the two lips into one design to separate two fluids from each other

Power Steering Seal

Shock Absorber Seal

Wiper seal

DESIGN CHARACTERISTICS	Automotive seals series
Hydrodynamic sealing lips are available with most designs. The helical ribs help "pump" the fluid back under the seal lip. Basic lip design is same as standard seal.

DESIGN CHARACTERISTICS	Compressor seals
Used for air conditional compressor

DESIGN CHARACTERISTICS	Pressure seals
(High Pressure) Type "TCN" is designed for high pressure applications where continuous pressure may reach 150 psi (10.6 kg/cm2). Maximum pressure limit is dependent on shaft speed.
(Medium Pressure) For applications up to 50 psi (3.5 kg/cm2), the "TCV" design is recommended. Pressure limit is dependent on shaft speed

DESIGN CHARACTERISTICS	PTFE seals
PTFE seals are designed for low friction, high-speed applications, or when the reductions of under running temperature are required. Used well for Vacuum Pumps.
