DPF Gasket Types

Yongyong’s DPF gasket range includes several exhaust sealing constructions for different DPF and exhaust connection applications. The current product range covers exhaust gaskets, exhaust ropes, and knitwire products identified by OE reference and Yongyong part number.

Exhaust Gaskets

Exhaust gaskets provide a sealing interface between connected components in diesel exhaust systems. Yongyong supplies gaskets in different shapes, dimensions, and constructions for selected DPF and exhaust applications.

Product selection should be based on the original OE reference, sealing structure, dimensions, and corresponding exhaust connection.

Exhaust Ropes

Exhaust ropes are flexible sealing components used in selected DPF and exhaust applications. Yongyong currently supplies exhaust rope products identified by OE reference and Yongyong part number, including selected applications for heavy-duty diesel exhaust systems.

The correct exhaust rope should be confirmed according to the original component, OE reference, dimensions, and application.

Knitwire Exhaust Sealing Components

Knitwire products are available for selected DPF and exhaust sealing applications. Yongyong supplies Knitwire products identified by OE reference and Yongyong part number, including OE 1927181 / YYSGSQ354.

Product selection should be confirmed according to the original component, dimensions, sealing configuration, and application.

How to Select the Right DPF Gasket

The correct gasket depends on the exhaust connection rather than the truck brand alone. Several technical details can help confirm the correct product.

OE Number

The original gasket or DPF OE reference is the preferred starting point for product identification. It can be used to check the corresponding Yongyong part number and product type.

Sealing Structure

The original component may use a flat exhaust gasket, exhaust rope, knitwire component, or another sealing construction. Matching the structure is important for proper installation.

Dimensions

Important dimensions may include inner diameter, outer diameter, thickness, sealing profile, and connection dimensions. Physical measurements are particularly useful when the original OE number is unavailable.

Exhaust Connection

The gasket must match the mating flange, pipe, DPF outlet, inlet, or other exhaust interface. Incorrect dimensions can result in poor sealing or installation problems.

Application Information

Truck brand, vehicle model, engine information, DPF reference, and exhaust configuration can help confirm the application when multiple products share similar OE references.

DPF Gaskets for Aftermarket Supply

Yongyong supplies DPF gaskets and exhaust sealing components for different aftermarket requirements.

Aftermarket Distributors

Distributors can source multiple OE references across European and North American truck applications. Products can be organized by OE number, Yongyong part number, brand, and product type for easier inventory management.

Repair Businesses

Repair and exhaust service businesses can source replacement gaskets when a DPF or exhaust connection is removed for replacement, cleaning, inspection, or repair.

Fleet Maintenance

Fleet maintenance programs may require repeated replacement of specific sealing components across multiple vehicle models. OE-based product identification helps maintain consistent sourcing.

Bulk Orders

Bulk supply is available for selected products based on the required OE references, product types, and quantities. Multiple references can be consolidated into one sourcing request when required.

DPF Gasket Materials and Construction

Different exhaust applications require different sealing constructions. Depending on the product, Yongyong gasket components may use graphite, stainless steel, composite, or other application-specific materials.

Material selection should consider the exhaust connection, operating temperature, compression requirements, and original component construction.

The appropriate material is determined by the specific product and application rather than using one material across the entire DPF gasket range.

DPF Gasket Replacement Applications

DPF gaskets are used at selected sealing points within diesel exhaust systems. Common replacement situations include:

• DPF replacement
• DPF removal and reinstallation
• Exhaust connection repair
• Exhaust component replacement
• DPF maintenance and inspection
• Exhaust leak repair
• Aftertreatment system servicing

A gasket should be replaced when the original sealing component is damaged, deformed, cracked, excessively compressed, or no longer provides a reliable seal.

Related DPF Exhaust Components

DPF gaskets are part of a larger diesel exhaust and aftertreatment system. Yongyong also supplies related components for DPF replacement and exhaust system maintenance.

Komponente	Main Function
DPF	Filters particulate matter from diesel exhaust
DPF-Klammer	Secures selected DPF and exhaust connections
DPF-Dichtung	Seals mating DPF and exhaust components
DPF-Bausatz	Combines selected DPF replacement components
Nachbehandlungs-Teile	Includes selected sensors and related components
Auspuffschelle	Secures selected exhaust system connections

For a complete replacement requirement, the gasket can be sourced together with the corresponding DPF, clamp, or other exhaust components according to the application.

Häufig gestellte Fragen

Can I identify a DPF gasket by OE number?

Yes. The OE number is the preferred reference for identifying a matching DPF gasket or exhaust sealing component. When the OE number is unavailable, product dimensions, photos, vehicle information, and the corresponding DPF reference can help confirm the application.

What is the difference between a DPF gasket and an exhaust rope?

They are different sealing constructions used for different exhaust connection designs. A conventional gasket uses a defined sealing profile, while an exhaust rope provides a flexible sealing interface. The correct option depends on the original component and connection structure.

Should the gasket be replaced when installing a new DPF?

A new gasket is generally recommended when the DPF connection is opened. The original sealing component may have been compressed, deformed, damaged, or affected by previous thermal cycles and may not provide the same sealing performance after reinstallation.

Can one gasket fit different DPF models?

Not necessarily. DPF systems can use different connection dimensions and sealing structures even within the same truck brand. OE reference, physical dimensions, and connection configuration should be checked before replacement.

What information is needed to match a DPF gasket?

The OE number is the most useful reference. If it is unavailable, provide the DPF number, vehicle or engine information, gasket dimensions, connection details, product photos, and required quantity.

Do you supply exhaust ropes as well as DPF gaskets?

Yes. The product range includes selected exhaust rope products in addition to exhaust gaskets and other sealing components. Product selection is based on the OE reference and corresponding exhaust application.

Can DPF gaskets be supplied in bulk?

Yes. Yongyong supports bulk sourcing for distributors, repair businesses, fleet maintenance programs, and aftermarket suppliers. Multiple OE references and quantities can be included in the same quotation request.

Can you match a gasket from a sample?

A physical sample can help with product identification when the original OE reference is unavailable. Dimensions, photos, application information, and other technical details can be used together with the sample to evaluate the corresponding product.

Why can the same OE number appear with different sealing products?

Some OE references may be associated with different sealing components, configurations, or replacement products. When this occurs, the product type, dimensions, and application should be checked rather than selecting a component based only on the OE number.

What should I provide for a DPF gasket quotation?

Provide the OE number and required quantity whenever possible. If the OE number is unavailable, send the DPF reference, truck or engine information, product photos, dimensions, connection details, and any available original part information.
