OEM Oil Filter Housing Cover O-Ring 06E115446 | VW/Audi

Genuine OEM Engine Oil Filter Housing Cover O-Ring For VW/Audi 06E115446

If you wrench on VW/Audi engines, you’ve likely chased drips around the oil filter housing. To be honest, nine times out of ten it’s the O-ring. This one—made in JULU INDUSTRY AREA, XINGTAI CITY, HEBEI PROVINCE, CHINA 055250—hits the sweet spot: OEM fit, proper compound, and the right hardness so it seals without crushing. I’ve seen too many “universal” rings turn glossy, flatten, then seep. This isn’t that.

Industry trend: hotter engines, longer intervals

Turbocharged EA-series engines run hotter, oils last longer, and service intervals stretch. That means the Genuine OEM Engine Oil Filter Housing Cover O-Ring For VW/Audi 06E115446 needs oil- and heat-resistant elastomers (typically FKM) that won’t take a compression set after thousands of heat cycles. Many customers say switching back to OEM spec immediately stops that faint, annoying weep.

Technical specifications (typical)

Part No.	06E115446 (Volkswagen/Audi OE reference)
Material	FKM (fluoroelastomer), ≈75±5 Shore A; NBR available on request
Temp range	≈ -20°C to +200°C (FKM); real-world use may vary with oil temp/load
Standards fit	ISO 3601 Class A tolerances, SAE J200/ASTM D2000 material coding (FKM family)
Compatibility	VW/Audi oil filter housing covers using 06E115446 (e.g., select TFSI engines)

Process flow, materials, and testing

Materials: OEM-grade FKM compound with anti-oxidant and anti-swell package; NBR option for lower-temp fleets.
Methods: precision compression molding → cryogenic deflashing → post-cure (≈200°C) → 100% visual + dimensional check.
Testing standards: ISO 3601 dimensional; ASTM D395-B compression set; ASTM D471 oil swell (IRM 903); hardness per ASTM D2240.
Service life: around 100,000–150,000 km or 5–8 years in typical duty, assuming proper torque and oil spec.
Industries: OEM assembly, dealership aftersales, independent workshops, fleet maintenance, remanufacturing.

Selected lab data (typical)

Compression set @150°C, 22h (ASTM D395-B): 18–22% (limit ≤25%).
Volume swell in IRM903 oil @150°C, 70h (ASTM D471): ≈3.2%.
Hardness: 75±3 Shore A (ASTM D2240).
Housing pressure leak test: 0 leakage @5 bar, 120°C for 2h (bench rig).

Why technicians prefer it

Correct cross-section and squeeze for the groove; no guessing.
Resists synthetic oils and high under-hood temperatures.
Stable torque retention; less “cold-flow” compared to soft aftermarket blends.

Vendor comparison (snapshot)

Vendor/Type	Material	Temp rating	Fit tolerance	Certs	Notes
Genuine OEM 06E115446	FKM 75A	≈ -20°C to +200°C	ISO 3601 Class A	ISO 9001, IATF 16949	Best sealing stability
Aftermarket Generic A	NBR 70A	≈ -30°C to +120°C	General	ISO 9001	Budget, may harden with heat
Silicone “universal” pack	VMQ	≈ -50°C to +200°C	Loose	—	Not oil-optimized; swells

Customization options

For fleets or private-label: durometer 70–80A, FKM/NBR selection, color ID (green/brown/black), branded packaging, batch traceability, PPAP documentation on request.

Quick case study

An independent Audi specialist swapped three leaking aftermarket rings on a 2.0 TFSI with the Genuine OEM Engine Oil Filter Housing Cover O-Ring For VW/Audi 06E115446. Torque to spec, fresh oil, two weeks of daily commuting—dry as a bone. The owner’s words, not mine.

Usage notes

Lightly oil the new ring; never reuse a flattened seal.
Inspect groove for nicks; verify cap torque per OE manual.
Match part number; “close enough” sizes tend to seep over time.

Certifications and compliance

Manufacturing aligned with ISO 9001 and IATF 16949. Dimensional checks per ISO 3601. Material validation to ASTM D2000 family; oil resistance verified by ASTM D471; compression set by ASTM D395-B.
