Non-Woven Oil Filter Gasket

BiaoDian supplies Non-woven Oil Filter Gasket for oil filter structures used in passenger vehicles and commercial vehicles.

This PET nonwoven piece is usually installed near the end cap or edge sealing area inside the filter assembly.

Its main job is to help keep the filter structure stable while maintaining sealing performance during engine operation.

Inside the filter, the material stays in contact with hot engine oil and repeated pressure changes.

Because of this, customers usually pay attention not only to thickness, but also to whether the material remains stable after long-term use.

For many factories, the gasket also needs to process smoothly during cutting, bonding, and assembly.

Specifications

Technical Parameters

Why do some oil filter structures use nonwoven gaskets?

In actual filter operation, the sealing area inside the filter continuously experiences:

• hot oil exposure

• oil pressure fluctuation

• vibration during engine operation

If the gasket structure becomes unstable, sealing performance may gradually change over time.

This is why many oil filter designs still use PET nonwoven gasket structures for support and sealing positions.

How does the gasket work inside the filter?

This material mainly works as a sealing and support layer.

After installation inside the filter structure:

• it helps hold the filter media in position

• supports the end-cap sealing area

• reduces movement caused by pressure changes

The PET structure also keeps relatively stable after long-term oil exposure.

It is not a filtration layer itself, but it helps maintain overall filter structure stability during operation.

Where is this gasket commonly used?

BiaoDian Non-woven Oil Filter Gasket is commonly supplied for:

• engine oil filter elements

• passenger vehicle oil filters

• commercial vehicle filter assemblies

• end-cap gasket structures

• edge sealing positions

• center tube support areas

These positions usually stay in contact with engine oil during operation.

What do customers usually focus on during sourcing?

For this type of gasket material, customers usually care more about production stability than complicated specifications.

Common concerns include:

• whether the material stays flat after cutting

• whether thickness remains consistent between batches

• whether bonding and assembly stay stable

• whether the structure changes after oil exposure

Once a specification works steadily in production, customers usually continue using the same material long term.

Certification & Quality Assurance

For automotive filtration materials, most customers do not only look at a specification sheet.

In actual production, they usually care more about things like:

• whether later batches stay consistent with approved samples

• whether the material behaves the same during processing

• whether the structure remains stable after long-term oil exposure

BiaoDian has completed related certifications including IATF 16949 and ISO 14001, along with third-party testing for items such as SVHC and heavy metals.

For ongoing projects, production follows the confirmed specification after sample approval.

Basic inspection is carried out before shipment to help keep later batches consistent with previously tested materials.

Packaging & Shipping

The material can be supplied in:

• rolls

• sheets

• die-cut pieces

Packaging is arranged according to transportation and processing requirements.

During shipment:

• moisture exposure is minimized

• deformation during transportation is reduced

• materials are packed for easier handling and storage

Export packaging can also be adjusted based on customer requirements.

FAQ

Q1: Is this material resistant to hot engine oil?

Yes. The PET structure remains relatively stable after long-term oil exposure.

Q2: Is this a filtration layer?

No. It mainly works as a sealing and support structure inside the filter assembly.

Q3: Can dimensions and thickness be customized?

Yes. Thickness, width, and die-cut shapes can be adjusted according to filter structure requirements.

Q4: Is sample testing available before bulk orders?

Yes. Sample rolls, sheets, and die-cut pieces can be provided for testing and evaluation.
