Carrier 38AK500410 2-1/8″ ODF x 2-1/8″ ODF Sweat Accumulator 390 Psig

Description

Carrier 38AK500410 Refrigerant Accumulator Overview

The Carrier 38AK500410 is a heavy-duty refrigerant accumulator engineered to protect compressors from liquid slugging in commercial and residential HVAC and refrigeration systems. Featuring 2-1/8″ ODF sweat connections on both the inlet and outlet, this accumulator integrates seamlessly into existing copper line sets and is rated for a maximum working pressure of 390 Psig — making it suitable for a wide range of operating conditions.

Multi-Refrigerant Compatibility

This accumulator is designed to work with multiple refrigerant types, offering broad application flexibility across new installations and retrofit projects:

• R12
• R22
• R134a
• R404a
• R407c
• R502
• R507

Application & Benefits

Accumulators are a critical line-of-defense component in any refrigeration or air conditioning system. By temporarily holding excess liquid refrigerant before it reaches the compressor suction port, the Carrier 38AK500410 helps prevent costly compressor damage caused by liquid slugging — a common issue during system startup, defrost cycles, or rapid load changes. The large 2-1/8″ ODF sweat connections make this unit ideal for high-capacity commercial systems where refrigerant flow rates are elevated. Its compatibility with both legacy refrigerants (R12, R22, R502) and modern alternatives (R134a, R404a, R407c, R507) means it can serve both existing equipment and new system builds.
