6 Standard Radial Shaft Seal Lip Designs

	Description	Recommended For
S	Single Lip With Garter Spring	Generally used for sealing lower pressure oil separating applications. Not Recommended for use in applications where the environment contains dirt or contaminants.
T	Dual Lip (Dust Lip) With Garter Spring	Generally used for sealing lower pressure oil separating applications. The additional dust lip provides increased protection for the main lip. The space between the two lips can also be filled with grease to limit shaft corrosion and allow brief operation without media lubrication.
D	Double Lip With Garter Spring	Designed to separate two media.
V	Single Lip Without Garter Spring	Generally used for sealing a non-pressure medium, especially for sealing grease or viscous fluids. These seals are also used for dust or dirt exclusion.
K	Dual Lip (Dust Lip) Without Garter Spring	Generally used for sealing a non-pressure medium, especially for sealing grease or viscous fluids. These seals are also used for dust or dirt exclusion.
U	Triple Lip Without Garter Spring	Generally used for sealing a non-pressure medium, especially for sealing grease or viscous fluids. These seals are also used for heavy dust or dirt exclusion.

7 Standard Radial Shaft Seal Can Designs

	Description	Recommended For
B	Outer Metal "L" Case	Most common and economical. Suitable for steel or cast iron housing. This case design gives a firm and accurate seat, but static sealing on the O.D. is limited.
C	Rubber Covered O.D.	Improved O.D. sealing in bores with minor imperfections and in soft alloy housings.
F	Rubber Covered O.D.	Similar to C but designed with an additional rubber covering fully protecting the internal steel case. Good option for applications prone to corrosion.
A	Outer Metal Case With Reinforcing Plate	Designed with an additional inner case providing increased structural rigidity when a more robust design is required. Good for larger diameters or when the seal is fitted from behind.
M	Outer Metal Case With Rubber Lining	Similar to B but designed with an additional covering to protect the internal face of the steel case from internal corrosion.
P	Outer Metal "P" Case	Designed for ease-of-removal and flange positioning.
D	"Heel" Case	Designed for reduced spring back and ease of installation. Combines sealability of rubber O.D. and bore retention of metal O.D.

OUB2/V17

Radial Shaft Seals OUB2 and V17 radial shaft seals are known for their durability and reliability, making them a popular choice for many applications. They are an important component to prevent lubricant leakage and contamination from outside substances.

View OUB2/V17 Details

TC9/LCO

The design features a separate lip and sleeve that work together to provide enhanced sealing capabilities and improved durability. The lip of the seal is responsible for preventing lubricant leakage, while the sleeve serves as a protective barrier against dirt, debris, and other contaminants that could damage the seal and assembly.

Pinion Seal

Engineered Seal Products' NEW high deflection pinon seal prevents leaks for the life of your frac pump power end. Our specific engineering focus on frac pump consumables stems from the pain of of the oil and gas completions market. Unplanned repairs and downtime cost unnecessary loss of performance and productivity.

MAD Seal

MAD Seals are a direct replacement for Pivot Joint O-rings using a 45° chamfer configuration. The primary lip offers a superior barrier of contamination with an Engineered Secondary Lip that controls primary lip sealing pressure

Mechanical Seals

Mechanical seals are precision-engineered devices designed to prevent leakage between two surfaces in relative motion, typically in rotating equipment such as pumps, compressors, and mixers.
