74R5061 A/C Accumulator – Peterbilt Mobile Air Conditioning

Description

The BTRAC 74R5061 A/C Accumulator helps protect mobile air conditioning systems by controlling refrigerant flow before it returns to the compressor. It separates liquid refrigerant from vapor and captures moisture. As a result, it helps prevent compressor damage and supports consistent A/C performance.

This accumulator uses 1-1/16″ female O-ring inlet and outlet connections, which allows direct installation into Peterbilt HVAC systems designed around O-ring fittings. Because both ports use the same connection size, installation remains straightforward while reducing potential leak points.

The cylindrical body measures 3-1/2 inches in diameter and 9-1/2 inches in overall length. Therefore, it fits well in tight chassis and engine-bay installations. In addition, the internal design supports proper oil return, which helps maintain long-term system reliability.

Based on confirmed image details and validated interchange usage, the 74R5061 accumulator is commonly used on Peterbilt® models 357, 375, 378, 379, and 385. Because these trucks often operate under long duty cycles, dependable refrigerant management remains critical for system longevity.
