Carrier 1771 1-3/8″ ODF Discharge Muffler

Description

The Carrier 1771 is a 1-3/8″ ODF discharge muffler engineered to reduce noise and dampen pulsations generated by the refrigeration compressor discharge line. Designed for use in commercial and residential refrigeration and air conditioning systems, this muffler helps protect downstream components from the pressure fluctuations and vibration that can shorten system life and reduce efficiency.

Key Features

• 1-3/8″ ODF (Outside Diameter Flare) connection for easy installation into existing refrigerant lines
• Discharge-side muffler design attenuates compressor pulsation and noise at the source
• Durable construction suitable for high-pressure discharge line environments
• Compatible with common refrigerants used in commercial and residential HVAC/R applications
• Genuine Carrier OEM replacement part — SKU 1771

Application

The Carrier 1771 discharge muffler is ideal for technicians servicing or replacing mufflers in Carrier-brand refrigeration and air conditioning equipment. Installing a properly sized discharge muffler helps minimize vibration transmission to the refrigerant piping, reduces audible compressor noise, and contributes to a quieter, longer-lasting system.
