DPF Clamp Types

Veefit Clamps

Yongyong supplies Veefit clamps for selected DPF and diesel exhaust applications. Product matching is based on the OE reference, connection configuration, dimensions, and corresponding DPF application.

Collar Clamps

Collar clamps are available for selected DPF and exhaust connections. The correct product depends on the OE reference, component interface, dimensions, and installation configuration.

Application-Specific Clamps

Some DPF clamp requirements are specific to the vehicle, DPF, or exhaust system configuration. For non-listed applications, Yongyong can evaluate available OE numbers, dimensions, samples, drawings, or product photos.

Why Proper DPF Clamp Matching Matters

A DPF clamp connects and secures components within a high-temperature diesel exhaust system. The clamp must match the connection structure and maintain the required fit during heat cycles, vibration, and normal vehicle operation.

An incorrect clamp may result in poor fit, exhaust leakage, installation difficulties, or premature loosening.

For this reason, clamp selection should consider the OE reference, clamp dimensions, connection type, DPF configuration, and vehicle application, rather than relying only on appearance.

DPF Clamps for Fleet and Aftermarket Applications

DPF clamps are commonly required during DPF replacement, exhaust system maintenance, and aftertreatment component servicing.

Yongyong supports several customer groups:

Fleet Maintenance

Fleet operators can source replacement clamps according to established OE references and recurring vehicle applications.

Aftermarket Distributors

Distributors can source multiple clamp references across different truck brands and applications.

Repair Businesses

Repair businesses can match replacement clamps to the DPF or exhaust component being serviced.

Wholesale Customers

Customers purchasing multiple references can provide OE numbers and quantities for consolidated sourcing.

DPF Replacement Components

A DPF replacement may require additional components depending on the exhaust configuration and condition of the existing system.

Yongyong provides selected related products for DPF and diesel aftertreatment applications.

Product	Function
DPF	Main diesel particulate filtration component
DPF-Klammer	Secures DPF and exhaust connections
DPF-Dichtung	Seals connected exhaust components
DPF-Bausatz	Combines selected replacement components
Auspuffschelle	Supports other exhaust system connections
Aftertreatment Sensors	Monitors applicable exhaust system conditions

Customers replacing a DPF can therefore source the required clamp and other selected components according to the application.

Bulk and Application-Based DPF Clamp Supply

Yongyong supports both established product references and application-based sourcing.

For standard products, customers can provide the OE number and required quantity for quotation.

For non-listed applications, available information may include:

• OE number
• DPF OE number
• Truck or engine information
• Clamp dimensions
• Connection type
• Product sample
• Technical drawing
• Product photos
• Required quantity

This information allows the application to be reviewed before product matching or manufacturing.

OE-Based DPF Clamp Development

When a required clamp is not included in the current product range, Yongyong can evaluate the application based on available technical information.

The evaluation may cover:

OE Reference: Confirm the original product reference and application.

Dimensional Information: Check diameter, connection dimensions, and relevant structural measurements.

Product Configuration: Review the clamp structure and connection method.

Application Information: Verify the corresponding DPF, vehicle, engine, or exhaust system.

Sample or Drawing: Use an existing component or technical drawing when available.

This approach supports aftermarket replacement requirements beyond the standard online product range.

Can’t find the required DPF clamp in the current product range?

Send us the OE number, DPF reference, vehicle information, product photos, dimensions, or required quantity.

Yongyong can review the application and advise on the appropriate aftermarket clamp or a potential product development solution.

Häufig gestellte Fragen

What is the difference between a Veefit clamp and a collar clamp?

They use different connection structures and are designed for different DPF or exhaust configurations. The correct type should be determined by the original clamp, OE reference, connection dimensions, and corresponding DPF application rather than by truck brand alone.

Should I replace the DPF clamp when replacing the DPF?

If the existing clamp is damaged, deformed, corroded, or no longer provides a secure connection, replacement is recommended. A new DPF should be installed with a clamp that matches the connection structure and required dimensions.

Can I use the same DPF clamp for different DPF models?

Not necessarily. Clamp compatibility depends on the connection design, diameter, flange or collar structure, and OE application. Two DPFs used on the same truck brand may still require different clamps.

How can I confirm the correct clamp if I only have the DPF OE number?

The DPF OE number can be used as a starting reference, but it may not provide enough information by itself. Providing the original clamp number, product photos, dimensions, or vehicle and engine details helps confirm the correct connection.

What dimensions are important when selecting a DPF clamp?

Important measurements may include the clamp diameter, connection diameter, flange or collar dimensions, and overall connection structure. Photos of both the clamp and the DPF connection are also useful for comparison.

Can you supply DPF clamps for discontinued or older truck applications?

Selected older and discontinued applications can be evaluated based on the original OE number, sample, dimensions, drawings, or photos. Availability depends on the specific application and required product configuration.

Can you develop a DPF clamp from a sample?

A sample can be used for application evaluation and product development when sufficient technical information is available. OE references, dimensions, drawings, and application details can further support the assessment.

Can I order DPF clamps in multiple OE references?

Yes. Distributors, repair businesses, and fleet customers can provide multiple OE references and quantities for consolidated sourcing and quotation.

Are DPF clamps available as part of a complete replacement package?

Selected clamps can be supplied together with DPFs, gaskets, kits, and other related exhaust components according to the application. This allows commonly required replacement parts to be sourced together.

What information should I provide for a DPF clamp quotation?

Provide the OE number whenever available, together with the required quantity. If the OE number is unavailable, send the DPF reference, vehicle or engine information, clamp dimensions, and clear product photos for evaluation.
