Lennox 17W04 Muffler

The Lennox 17W04 Muffler (OEM part 100304-01) is a professional-grade acoustic attenuation component designed for high-performance HVAC systems. This refrigerant line muffler features a 1.59-inch diameter and 4.38-inch length, specifically engineered to handle pressure variations while mitigating low-frequency operational noise. Built with a 1/2-inch inlet and outlet connection size, it provides a seamless fit for Lennox condensing units and residential furnaces. As a veteran technician knows, maintaining strict decibel control is critical in light commercial and residential applications to prevent sound transmission through the structure.

Constructed for industrial durability, the 17W04 utilizes a specialized sound-absorbing core that dissipates acoustic energy as heat. This design avoids the airflow restrictions often found in inferior aftermarket parts, ensuring the HVAC compressor operates within specified parameters. Whether you are performing a Lennox furnace repair or a new system installation, this OEM muffler is the industry standard for reducing vibration and line sets noise.

Key Benefits:

• Superior noise reduction through a high-density acoustic panel core.
• Optimized 1/2" connection size for broad compatibility with Lennox HVAC equipment.
• Durable construction capable of withstanding the rigors of high-pressure refrigerant environments.
• Compact 4.38" profile allows for easy integration within tight cabinet spaces or line sets.
• Authentic Lennox replacement part ensures exact fit and maintains original system engineering.

Common Questions:

Will this muffler restrict refrigerant flow?
No, the Lennox 17W04 is engineered to attenuate sound waves without creating significant pressure drops, preserving the volumetric efficiency of the system.

Does this part work for gas furnace exhaust applications?
While this specific 17W04 model is commonly used in refrigerant and gas furnace configurations for noise control, always verify your specific model's requirements against the manufacturer’s technical manual.

Can I install this on a non-Lennox system?
While it features standard 1/2" connections, it is optimized for Lennox equipment. Contractors should confirm that the dimensions and pressure ratings align with the alternative system's specifications.
