Copper Metric Bonded Seal Dowty Washer 78pcs BUSY-CORNER High Pressure

Description

Product Overview

The 78‑piece Copper Metric Bonded Seal Dowty Washer set from BUSY‑CORNER is engineered to meet the demanding requirements of modern automotive and industrial systems. Each washer integrates a solid copper core with a resilient rubber sealing element, creating a self‑centred, high‑pressure seal that resists oil, coolant, and temperature fluctuations. The assortment covers ten metric sizes ranging from M6 to M24, providing comprehensive coverage for threaded pipe fittings, plug sealing, and a variety of BSP and British standard connections. The copper‑rubber construction delivers superior durability, maintaining seal integrity even after repeated installation cycles. All 78 pieces are organized in a transparent, impact‑resistant plastic case, allowing technicians to locate the exact size quickly, reducing downtime and minimizing the risk of using an incorrect component.

Usage

These bonded seals are ideal for high‑pressure oil lines in automotive engines, transmission systems, and hydraulic circuits. They also excel in industrial applications such as pneumatic tools, compressors, and fluid control valves where reliable sealing is critical. The self‑centred design ensures that the washer aligns perfectly with the mating surface, eliminating the need for additional alignment tools. Whether you are assembling a new engine, performing routine maintenance, or retrofitting an older system, the 78‑piece set provides the flexibility to address a broad spectrum of sealing challenges. The metric sizing aligns with ISO standards, making the set compatible with most modern equipment, while the inclusion of British Standard Pipe (BSP) and British System dimensions expands its utility across legacy installations.
