Description
Overview:
This Genuine Husqvarna gasket kit is a direct-fit replacement for the small two-stroke engines used in the 525BX handheld blower and 322L grass trimmer. It is designed to restore airtight and gas-tight joints across key engine interfaces so your machine starts easily, idles steadily and delivers full power. The set uses durable, fuel‐resistant gasket materials suited to the petrol/oil mix and heat cycles typical of handheld equipment. Correct sealing prevents loss of compression and stops air or exhaust leaks that can lead to poor running and premature wear. Sized to OEM specifications, the gaskets align accurately with ports and fastener holes for straightforward fitting with standard workshop tools. Ideal for scheduled servicing or repairs when old gaskets become brittle, torn or crushed.
Key Features:
- Genuine Husqvarna OEM part for assured compatibility and reliability on specified models
- Restores proper sealing at intake, crankcase, cylinder and exhaust joints to maintain compression and performance
- Materials selected for resistance to petrol, oil and engine temperatures, supporting long service life
- Manufactured to OEM dimensions for accurate alignment and a clean fit without trimming
- Helps prevent vacuum leaks that cause hard starting, erratic idle and loss of power
- Supplied as a matched set for common engine sealing points to simplify maintenance
- Suitable for professional workshops and DIY users; straightforward to install during routine overhauls
- Supports efficient running, reducing the risk of secondary damage from air or exhaust leaks
Typical Applications:
Used during engine rebuilds, carburettor servicing, muffler replacement, cylinder work, or crankcase resealing on Husqvarna handheld equipment. Common in landscaping, grounds maintenance and domestic garden care to keep blowers and trimmers running reliably through regular use.
