What Is Part Number 1J0955998C?
Part number 1J0955998C is a genuine Volkswagen group EPDM rubber grommet that functions as a protective boot for the windshield washer hose and an associated wiring cable, sealing both lines together as they pass through a single sheet metal opening near the hood or trunk area. Its asymmetric dual-port design separates the fluid hose from the cable, allowing each line to be routed through its own appropriately sized channel rather than sharing one opening. This part is molded specifically to Volkswagen Group specifications, ensuring it matches the exact panel cutout and sealing geometry used on applicable models.
Key Features
Direct OE Replacement
Specifically molded to Volkswagen Group specifications under part number 1J0955998C, ensuring 100% compatibility with the original factory panel opening and mounting geometry.
Asymmetric Dual-Port Engineering
Features one thick fluid-hose routing port for the washer line and one extended slender cable port for wiring, preventing line kinking and providing excellent strain relief during dynamic trunk or hood movements.
Heavy-Duty EPDM Compound
Provides reliable seal protection against washer fluids, UV rays, ozone aging, and harsh under-hood temperatures ranging from -40°C to +120°C.
Anti-Rotation Oval Base
The specialized elliptical grooved flange snaps securely into corresponding sheet metal openings, delivering superior water-tight and dust-proof sealing performance while resisting rotation once installed.
Why the Dual-Port Design Matters
Combining a fluid hose port and a cable port into one grommet keeps both lines organized at a single body opening, rather than requiring two separate seals that could each become potential leak or dust entry points. The asymmetric port sizing, with a thicker channel for the washer hose and a slimmer channel for the cable, reduces the risk of either line being pinched, kinked, or subjected to excess flex stress as the hood or trunk moves during normal vehicle operation. This design approach also improves strain relief at the pass-through point, helping extend the service life of both the hose and the wiring harness.
Why EPDM Material
EPDM rubber is widely used for automotive washer hose boots and cable grommets because of its strong resistance to washer fluid chemicals, UV exposure, and ozone aging, all of which are relevant to components mounted in exposed hood or trunk locations. The heavy-duty EPDM compound used in this grommet also maintains flexibility and sealing integrity across a wide temperature range of -40°C to +120°C, ensuring reliable performance from cold winter starts through hot under-hood conditions. This combination of chemical, weather, and thermal resistance makes EPDM a durable choice for a component that is rarely replaced during routine maintenance.
Anti-Rotation Oval Base Explained
The grommet’s base uses a specialized elliptical grooved flange rather than a simple round profile, which snaps securely into the corresponding oval sheet metal opening and resists twisting or rotating once installed. This anti-rotation feature helps maintain consistent alignment of the dual-port channels relative to the hose and cable routing, preserving the water-tight and dust-proof seal over the life of the vehicle.
Common Applications
- Hood-to-body washer hose and wiring pass-through points.
- Trunk lid washer line and cable routing on applicable VW models.
- Rear windshield washer system hose and wiring boot.
- Body panel openings requiring combined fluid and electrical line sealing.
Why Choose Genuine OEM Grommets
Genuine Volkswagen group parts like 1J0955998C are manufactured to the exact specification used in original vehicle assembly, ensuring correct fit, sealing performance, and long-term durability compared with generic aftermarket alternatives. Because this component manages both a fluid hose and a wiring cable at a dynamic body opening, an exact OEM match is especially important, since a mismatched aftermarket boot could result in washer fluid leaks, wiring chafing, or water intrusion. Confirming the exact part number against your vehicle’s parts catalog or VIN-based lookup is recommended before ordering.
FAQ
What is the OEM 1J0955998C automotive EPDM rubber grommet used for?
It is used as a windshield washer hose protective boot and line-routing grommet for VW applications where part number 1J0955998C is required. It helps protect washer hoses and related lines from panel edge abrasion, kinking, dust and water ingress.
What is the function of the asymmetric dual-port design?
The asymmetric dual-port design separates one thick washer fluid hose path from one extended slender cable or line path. This structure helps reduce line interference, supports strain relief and improves routing stability during repeated trunk or hood opening and closing movements.
Why is EPDM used for this windshield washer hose grommet?
EPDM is used because the product requires resistance to washer fluids, UV rays, ozone aging and automotive environmental exposure. The provided temperature range is -40°C to +120°C. Final compound approval should still consider installation position, compression and required documentation.
Can the dimensions be customized?
Yes. Oval base size, groove width, panel fit, thick hose port diameter, slender cable port diameter, port length and dimensional tolerance can be customized according to OE specification, drawing or original sample. Unsupported dimensions should not be assumed.
Is this a genuine Volkswagen part?
This page describes a custom or replacement automotive EPDM rubber grommet identified by part number 1J0955998C. Volkswagen, VW and OE references are used for identification and compatibility review only. Buyers should confirm whether they require aftermarket production, replacement supply or official sourcing.
Are samples available before bulk production?
Samples are available upon request. Sample preparation depends on confirmed dimensions, EPDM compound, Shore A hardness, color, tooling status and inspection requirements. An original sample, drawing or OE specification is recommended before batch production to verify fit and function.
