Description
Overview:
This Husqvarna-referenced O ring (OEM No. 740 48 18 04) is a durable black rubber sealing ring used across garden and construction equipment. It provides a tight, reliable seal between mating parts in fuel, oil and air paths, pump housings and hose couplings, helping machinery run smoothly and efficiently. Sized at 29.74 mm x 3.53 mm, it matches the original specification for a straightforward like-for-like replacement during maintenance. The resilient rubber compresses evenly to maintain pressure or vacuum and resist leakage under normal operating conditions. Suitable for common Husqvarna machines such as chainsaws, brushcutters, mowers, blowers and cut-off saws, this compact spare is practical to keep in the toolbox for workshop repairs and routine servicing where an OEM-numbered seal is required.

- Precise 29.74 mm x 3.53 mm sizing for an accurate fit and dependable sealing performance

- Easy to fit; compresses evenly without special tools in most applications

Typical Applications:
Sealing connections in small engine and equipment systems, including fuel line unions, carburettor interfaces, primer and pump housings, tank caps, hose couplings, and general-purpose fittings on chainsaws, trimmers, brushcutters, lawn mowers, blowers and cut-off saws.
