- Leak Prevention at Critical Joints — A correctly seated seal washer prevents fluid or pressure loss at fastened connections, protecting surrounding components from contamination and wear.
- Verified OEM Part Number — Ordering by Husqvarna part number 740380801 confirms you receive the exact component specified for your machine, eliminating guesswork during service.
A seal washer functions as a combined fastener and sealing element, using a deformable sealing layer bonded to or integrated with the washer face to create a pressure- or fluid-tight barrier at a bolted joint. When tightened, the sealing material compresses against the mating surface, blocking the passage of fluid, air, or contaminants around the fastener. Over time or after repeated assembly cycles, the sealing layer can harden, crack, or deform unevenly, allowing leaks to develop at the joint. Replacing a worn seal washer with the correct OEM component restores that barrier and prevents progressive damage to the assembly.
