Oil Filler Cap
An oil filler cap is a component of an internal combustion engine, serving as the primary seal for the engine’s oil reservoir. It prevents contaminants from entering the engine while allowing access for oil addition and dipstick insertion.
Material
Oil filler caps are typically constructed from the following materials:
- Plastic: Most common for modern vehicles due to cost-effectiveness, lighter weight, and resistance to corrosion. Often polypropylene or similar polymers.
- Metal: Traditionally made from aluminum or steel. Still found in high-performance applications or older vehicles, offering greater durability and heat resistance.
- Rubber/Sealing Components: A rubber O-ring or gasket is integral to the cap's design, ensuring a leak-proof seal.
Purpose
The primary functions of an oil filler cap are:
- Seal the Oil Reservoir: Prevents dirt, debris, and moisture from contaminating the engine oil.
- Maintain Oil Pressure: Contributes to maintaining proper crankcase pressure.
- Allow Oil Addition: Provides access for adding oil to the engine as needed.
- Provide Dipstick Access: Often integrated with or located directly adjacent to the oil dipstick tube.
Function
The cap functions through a simple yet effective design:
- Threaded Connection: The cap typically features a threaded connection to the oil fill neck, allowing it to be securely tightened.
- Sealing Mechanism: The rubber O-ring or gasket compresses when the cap is tightened, creating a hermetic seal.
- Baffle/Internal Design: Some caps incorporate internal baffles or designs to reduce oil splash during operation.
- Pressure Relief (Some Models): Certain caps may include a pressure relief valve to prevent excessive crankcase pressure buildup.
Usage Scenarios
- Routine Oil Checks: Removed to check oil level using the dipstick.
- Oil Addition: Removed to add oil to the engine when levels are low.
- Engine Maintenance: Removed during oil changes and other engine maintenance procedures.
- Inspection: Regularly inspected for cracks, damage, or proper sealing.
Common Types
- Standard Oil Filler Cap: The most common type, typically a simple threaded cap with a basic seal.
- Twist-Lock Oil Filler Cap: Features a twist-lock mechanism for enhanced security.
- Push-In Oil Filler Cap: Secured with a push-in mechanism and retaining clips.
- Colored Oil Filler Caps: Often used for aesthetic purposes or to differentiate oil types.
- High-Performance Oil Filler Caps: Constructed from metal with enhanced sealing features for high-performance engines.
- Billet Aluminum Oil Filler Caps: Premium caps often used in custom or modified vehicles, offering a distinctive appearance and improved durability.
Based on the provided information, identifying the precise HS code for an "oil filler cap" requires careful consideration of its material and application. Here's a breakdown of potentially relevant HS codes:
- 7326908688: Other articles of iron or steel. This code covers a broad range of iron or steel articles. If the oil filler cap is made of iron or steel, this is a potential match. The total tax rate is 82.9%, comprised of a 2.9% basic tariff, a 25.0% additional tariff, and a 30.0% additional tariff applicable after April 2, 2025. Note that this code also applies to steel and aluminum products with a 25% additional tariff.
- 7419801500: Other articles of copper; Containers of a kind normally carried on the person, in the pocket or in the handbag. If the oil filler cap is made of copper and is small enough to be considered a container normally carried on a person, this code might apply. The total tax rate is 58.0%, consisting of a 3.0% basic tariff and a 25.0% additional tariff, increasing to 30.0% after April 2, 2025.
- 7419805050: Other articles of copper; Other. If the oil filler cap is made of copper but doesn't fall into the "containers" category, this code could be relevant. The total tax rate is 55.0%, with a 0.0% basic tariff and a 25.0% additional tariff, rising to 30.0% after April 2, 2025.
- 8481801050: Taps, cocks, valves and similar appliances, for pipes, boiler shells, tanks, vats or the like, including pressure-reducing valves and thermostatically controlled valves; parts thereof: Other appliances: Hand operated: Of copper Having a pressure rating under
850 kPa: Other. If the oil filler cap functions as a valve for a tank, and is made of copper with a pressure rating under 850 kPa, this code may be applicable. The total tax rate is 59.0%, consisting of a 4.0% basic tariff, a 25.0% additional tariff, and a 30.0% additional tariff after April 2, 2025.
According to the provided reference material, the HS code options related to 'oil filler cap' are limited, with only the following 4 found.
It is important to determine the precise material composition (iron/steel, copper, or other) and function of the oil filler cap to select the correct HS code.
