Bosch 87101031530

Product Overview

The Bosch 87101031530 is a high‑performance seal (dichtung) designed specifically for use in gas heating systems. It serves as an essential component that ensures the integrity and safety of gas boilers, heat exchangers, and related equipment. The seal’s precise engineering allows it to withstand the demanding operating conditions typical of residential and commercial heating installations.

Key Functionalities

Sealing Integrity: The 87101031530 is engineered to create a reliable barrier against gas leaks, maintaining pressure within the system and preventing hazardous emissions. Its robust construction ensures long‑term performance even under fluctuating temperatures and pressures.

Compatibility: This seal fits seamlessly with a range of Bosch heating units, including models such as KBR/KSBR, ZB/ZBR, ZBS, and ZSB/ZW. It is also suitable for use in other brands’ systems where the same dimensional specifications apply.

Ease of Installation: Designed with user convenience in mind, the seal can be installed or replaced without extensive disassembly. Its standardized dimensions allow technicians to perform maintenance quickly and accurately.

Material Composition

The 87101031530 is manufactured from a premium rubber compound that offers excellent resistance to thermal expansion, chemical corrosion, and mechanical wear. This material selection guarantees durability across the typical temperature range of gas heating units (from -10 °C to +120 °C) while maintaining flexibility for proper sealing.

Applications in Heating Systems

Gas Boilers: The seal is commonly used on the front cover of gas boiler bodies, ensuring a tight fit that prevents leakage during operation. It also protects the internal components from external contaminants.

Heat Exchangers: In systems where heat exchangers are integrated with gas boilers, the 87101031530 provides a critical seal between the exchanger housing and the boiler shell.

Maintenance Covers: For routine inspections or cleaning procedures, this seal can be fitted to maintenance covers (e.g., WB5-II+), allowing safe access while preserving system integrity.

Installation Guidelines

1. Preparation: Clean the sealing surface thoroughly to remove dust, grease, and old gasket material. Ensure the area is dry before proceeding.
2. Alignment: Position the seal so that its groove aligns perfectly with the mating component’s edge. Misalignment can lead to uneven pressure distribution and potential leaks.
3. Compression: Apply uniform pressure along the entire circumference of the seal using a calibrated tool or hand tightening, depending on the system specifications.
4. Verification: After installation, perform a pressure test or visual inspection to confirm that no gaps exist. The seal should maintain its shape without deformation under operating conditions.

Maintenance and Longevity

Regular inspections are recommended to detect early signs of wear such as cracks, hardening, or loss of elasticity. When a seal shows any degradation, it should be replaced promptly to avoid compromising system safety. Proper storage—away from direct sunlight and extreme temperatures—extends the life expectancy of the 87101031530.
