Norlake 157591 Capillary Tube for NLBB59 69 7

Product Description

The NORLAKE 157591 is a replacement capillary tube designed for use in NORLAKE commercial refrigeration equipment. A capillary tube is a fixed-bore metering device that controls refrigerant flow from the high-pressure side to the low-pressure side of the refrigeration circuit, replacing the function of an expansion valve in smaller sealed systems. This component is a direct OEM-style replacement part, intended for installation by qualified refrigeration technicians servicing NORLAKE commercial appliances.

This capillary tube is specified for use with NORLAKE NLBB59 69 7 series commercial refrigeration units. These units are typically found in commercial foodservice and cold storage environments. Proper refrigerant metering is critical to maintaining correct evaporator temperature, system efficiency, and food safety compliance in these applications.

Key Features

• OEM-style replacement capillary tube for NORLAKE commercial refrigeration systems
• Fixed-bore design meters refrigerant flow without moving parts
• Designed for direct fitment in NLBB59 69 7 series units
• Maintains proper refrigerant circuit balance for consistent cooling performance

Compatibility

Specified for NORLAKE NLBB59 69 7 series commercial refrigeration equipment.

Installation Notes

Capillary tube replacement should be performed by an EPA 608-certified refrigeration technician. The system must be properly recovered of refrigerant before any refrigeration circuit work begins, in compliance with EPA regulations. Brazing equipment and appropriate flux are typically required for capillary tube replacement. After installation, the system must be leak-tested, evacuated, and recharged to manufacturer specifications before returning the unit to service.
