What Does CORTECO 12016274 FPM B1BASLRSX7 Mean?

CORTECO - Manufacturer

CORTECO is a brand within the Freudenberg Group, specialising in sealing solutions and technical components for automotive, agricultural and industrial applications.

The manufacturer part number 12016274 identifies a specific rotary shaft oil seal measuring 114x135x13 mm and featuring the B1BASLRSX7 construction profile.

114x135x13 mm - Installation Dimensions

The dimensional designation identifies three essential measurements:

• 114 mm - nominal diameter of the shaft sealing surface.

• 135 mm - nominal diameter of the housing bore.

• 13 mm - nominal axial width of the oil seal.

All three dimensions must be checked together with the sealing profile and manufacturer part number.

FPM/FKM - Fluoroelastomer

FPM and FKM are alternative designations for the same general family of fluorocarbon elastomers.

Fluoroelastomers are commonly used in sealing applications requiring resistance to many oils, lubricating greases, fuels and elevated temperatures.

Actual resistance depends on the specific elastomer compound, operating medium and service conditions.

B1BASLRSX7 - Special CORTECO Seal Profile

B1BASLRSX7 identifies a specific CORTECO rotary shaft seal construction.

It should not automatically be considered equivalent to conventional BA, BASL, B1 or standard double lip oil seal profiles.

Individual elements of the designation may refer to construction characteristics, but their precise interpretation for this product requires confirmation from the manufacturer's catalogue.

When selecting a replacement, the complete profile designation and equipment requirements must be considered.

Construction of CORTECO B1BASLRSX7

Radial Shaft Sealing

The oil seal operates where a rotating shaft passes through a mechanical housing.

Its sealing element works in contact with the shaft surface, restricting the escape of oil or another compatible lubricant.

The sealing performance depends on the complete operating arrangement, including shaft condition, lubrication, temperature and installation quality.

Special Sealing Profile

B1BASLRSX7 is a specific radial shaft seal profile.

Compared with conventional oil seals, special profiles may differ in:

• Sealing lip geometry.

• Additional sealing elements.

• Outer case construction.

• Contact position on the shaft.

• Installation requirements.

• Operating characteristics.

For this reason, an oil seal with identical dimensions but a different profile may not provide equivalent performance.

Shaft Contact Surface

The nominal shaft sealing diameter is 114 mm.

The condition of the shaft surface directly affects sealing performance and service life.

Important factors include:

• Appropriate surface roughness.

• Absence of mechanical damage.

• Protection against corrosion.

• Correct shaft geometry.

• Suitable lubrication.

• Controlled radial shaft runout.

Housing Installation

The outer section of the seal is designed to fit into a housing bore with a nominal diameter of 135 mm.

Correct fit and installation are essential for stable positioning and effective sealing at the housing interface.

FPM/FKM Material Properties

Resistance to Mineral Oils

FPM/FKM generally provides good resistance to many mineral-based lubricating oils.

This is an important characteristic in mechanical transmissions and industrial lubrication systems.

Resistance to Industrial Greases

Fluoroelastomers can be suitable for contact with many industrial lubricating greases, provided chemical compatibility is confirmed.

Elevated Temperature Resistance

FPM/FKM generally offers better resistance to elevated temperatures than standard NBR rubber.

However, a specific operating temperature range should not be assigned to CORTECO 12016274 without verified manufacturer data.

Chemical Resistance

Many FPM/FKM compounds provide favourable resistance to selected hydrocarbons, oils and fuels.

This does not mean that the material is compatible with every chemical substance.

Is FPM the Same as Viton?

Not necessarily.

FPM/FKM is a general designation for fluoroelastomers, while Viton is a registered trademark for specific fluoroelastomer materials.

The FPM designation alone does not confirm that this CORTECO seal contains genuine Viton-branded material.

Why Is the B1BASLRSX7 Profile Important?

Oil seals with identical dimensions can have significantly different internal constructions.

Potential differences include:

• Primary sealing lip geometry.

• Additional sealing elements.

• Shaft contact arrangement.

• Outer case construction.

• Installation orientation.

• Elastomer material.

• Operating characteristics.

Therefore, a standard 114x135x13 mm rotary shaft oil seal is not automatically a suitable replacement for CORTECO 12016274.

Can a Standard TC Oil Seal Replace B1BASLRSX7?

Not automatically.

A standard TC profile generally identifies a double lip rotary shaft oil seal, but this does not establish equivalence with the specific CORTECO B1BASLRSX7 construction.

Even if dimensions and material match, the sealing geometry and application requirements may differ.

FPM vs NBR - Material Comparison

An FPM seal should not automatically be replaced with an NBR version, even when the dimensions are identical.

The operating fluid, temperature and complete seal construction must be considered.
