Elring 031.046 Seal Ring

The Elring 031.046 Seal Ring is a precision‑engineered component designed to provide reliable sealing for oil drain plugs and sump fittings in automotive and commercial vehicle applications. Crafted from high‑performance copper alloy, this ring delivers exceptional resistance to heat, pressure, and chemical exposure, ensuring long‑term integrity of the engine’s lubrication system.

Key Features

• Material Excellence: Made from a proprietary copper alloy blend that offers superior thermal conductivity and corrosion resistance.
• Exact Dimensions: Standard size of 26 mm diameter, 34 mm length, and 2 mm thickness—matching the specifications required for most OEM oil drain plugs.
• High‑Temperature Tolerance: Capable of operating safely at temperatures up to 200 °C without deformation or loss of sealing capability.
• Pressure Resistance: Maintains a tight seal under internal pressures typical of engine oil systems, preventing leaks during both normal operation and high‑load conditions.
• Chemical Compatibility: Resistant to common automotive oils, additives, and coolant mixtures, ensuring durability across diverse operating environments.

Applications

The Elring 031.046 Seal Ring is widely used in a variety of vehicle platforms, including but not limited to:

• MERCEDES‑BENZ models such as the T2/L and LN1 series.
• TOYOTA Land Cruiser and other heavy‑duty vehicles.
• MITSUBISHI, BOVA, DAF, and DRÖGMÖLLER commercial trucks.
Porsche, Renault Trucks, and MAN engines that require a reliable oil drain plug seal.

Installation Guide

Installing the Elring 031.046 Seal Ring is straightforward when following these steps:

1. Preparation: Clean the oil drain plug threads and the surrounding area with a solvent to remove old gasket material, dirt, and debris.
2. Positioning: Slide the seal ring onto the plug head, ensuring it sits flush against the threaded portion. The copper alloy side should face outward toward the engine block.
3. Tightening: Insert the plug into the drain opening and tighten to the manufacturer’s specified torque using a calibrated wrench or torque screwdriver.
4. Verification: After installation, check for any signs of oil leakage around the plug. A properly seated seal ring will prevent fluid escape under normal operating conditions.

Maintenance Tips

• Inspect the seal ring during routine maintenance or when changing engine oil to ensure it remains intact and free from cracks.
• Avoid using abrasive cleaners on the copper surface, as they can compromise the integrity of the material.
• If a leak is detected, replace the seal ring immediately—continuing operation with a damaged ring may lead to engine damage or reduced oil pressure.
