50Pcs 1/2″ BSP Bonded Sealing Washers 21.54 x 28.58 x 2.5mm for Hydraulic System Industrial Sealing

Description

Product Overview

The LT Easiyl 1/2″ BSP Bonded Sealing Washers are engineered to meet the demanding requirements of modern hydraulic and industrial applications. Each washer measures 21.54 mm inner diameter, 28.58 mm outer diameter, and 2.5 mm thickness, providing a precise fit for standard 1/2″ BSP connections. The outer layer is constructed from galvanized carbon steel, delivering exceptional durability and resistance to corrosion in harsh environments. Inside, a nitrile rubber layer offers superior oil resistance, elasticity, and temperature stability, ensuring a tight, leak‑free seal even under fluctuating pressure conditions. The self‑centering design automatically aligns the washer during installation, reducing the risk of misalignment and uneven wear. Packaged in a convenient box of 50 units, these washers are ideal for bulk purchases, maintenance inventories, and large‑scale projects where consistency and reliability are paramount.

Usage

These sealing washers are suited for a wide range of hydraulic systems, including mobile equipment, stationary machinery, and high‑performance industrial tools. They excel in applications such as hydraulic cylinders, pumps, valves, and actuators where a secure, oil‑tight seal is critical to prevent fluid loss and maintain system efficiency. Construction machinery, agricultural equipment, and manufacturing lines also benefit from the washer’s robust construction, as the galvanized steel resists rust caused by exposure to moisture and chemicals, while the nitrile rubber tolerates hydraulic oil, synthetic fluids, and temperature variations from -30 °C to +120 °C. Maintenance technicians, engineers, and procurement specialists will find the 50‑piece pack convenient for routine servicing, emergency repairs, and stock‑keeping, ensuring that replacement parts are always on hand when downtime must be minimized.

FAQ

What makes the self‑centering feature important for hydraulic applications?

The self‑centering feature automatically aligns the washer with the mating surface during installation, eliminating the need for manual alignment tools. This reduces installation time, minimizes the risk of uneven pressure distribution, and helps prevent premature wear or leakage caused by misalignment. In high‑pressure hydraulic systems, consistent sealing pressure is essential for maintaining system efficiency and safety.

Can these washers be used with fluids other than hydraulic oil?

Yes. The nitrile rubber inner layer is compatible with a variety of fluids, including synthetic hydraulic fluids, coolant mixtures, and certain chemical solvents. However, it is recommended to verify chemical compatibility for highly aggressive substances. The galvanized steel outer ring is resistant to most corrosive agents, but prolonged exposure to strong acids or bases may affect its performance.

How do I verify that the washers are the correct size for my equipment?

Each washer is sized to a 1/2″ BSP (British Standard Pipe) thread, with an inner diameter of 21.54 mm and an outer diameter of 28.58 mm. To confirm fit, measure the bore of the component where the washer will be placed and compare it to these dimensions. The 2.5 mm thickness is standard for most BSP sealing applications, ensuring adequate compression without over‑tightening.

What warranty or guarantee does LT Easiyl provide?

LT Easiyl offers a limited one‑year warranty covering material defects and manufacturing inconsistencies. If a washer fails due to a defect within the warranty period, we will replace the affected units at no additional cost. Our technical support team is available to assist with any installation or performance concerns, ensuring you receive the full benefit of our quality commitment.
