JB INDUSTRIES

The JB Industries evacuation pump oil, such as the Black Gold series, is an ISO-46 viscosity grade oil. It is supplied in a 1 qt bottle and is yellow in color. This oil is designed for lubricating and maintaining vacuum pumps during HVAC/R system evacuation, helping to remove moisture and contaminants. The ISO-46 grade indicates a kinematic viscosity of approximately 46 mm²/s at 40°C, which is suitable for many vacuum pump applications. Always refer to the pump manufacturer's specifications for the recommended oil viscosity.

JB Industries valve cores, such as the A31999-25, are constructed from brass and feature a PTFE barrel gasket seal and a neoprene cup washer. They have a length of 2-3/8 inches and a connection size of 1/4 inch. These cores are used in HVACR service ports for refrigerant charging, evacuation, or testing. The PTFE and neoprene materials provide chemical resistance and a reliable seal. The cores are compliant with environmentally preferable product criteria. They are available in packs, and the MPN is A31999-25.

JB Industries capillary tubing is available in various sizes to suit different refrigeration and HVAC applications. Common inside diameters include 0.031 in, 0.049 in, 0.05 in, 0.059 in, and 0.1 in. Outside diameters range from 0.083 in to 0.114 in. Lengths include 10 ft, 11 ft, 12 ft, and 100 ft. For example, the TC-31-12 has a 0.031 in ID, 0.083 in OD, and 12 ft length; the TC-100-10 has a 0.1 in ID, 10 ft length. The tubing is made of copper and acts as a metering device to control refrigerant flow.

JB Industries capillary tubing serves as a metering device in refrigeration and HVAC systems. It controls the flow of refrigerant from the condenser to the evaporator by providing a precise pressure drop. The small inside diameter creates resistance to flow, which helps maintain the pressure difference between the high side and low side of the system. This allows the refrigerant to expand and absorb heat in the evaporator. The tubing is made of copper, which is compatible with common refrigerants and offers good thermal conductivity. Selection depends on system capacity and refrigerant type.

JB Industries valve cores, such as the A31999-25, have a connection size of 1/4 inch. This is a standard size for many HVACR service ports. The core length is 2-3/8 inches. The connection size refers to the thread or fitting size that mates with the service port. It is important to match the connection size to the port to ensure a proper seal and function. These cores are used in charging, evacuation, and testing procedures. Always verify compatibility with your specific equipment.

JB Industries evacuation pump oil, such as the Black Gold series, meets ISO 46 viscosity grade standards. ISO 46 is a classification for industrial lubricants based on kinematic viscosity at 40°C. This oil is specifically designed for use in evacuation pumps during HVAC/R service. It helps lubricate the pump mechanism and assists in removing moisture and contaminants from the system. The oil is supplied in a 1 qt bottle. For specific pump requirements, consult the pump manufacturer's recommendations. The product is not a certification but a viscosity classification.
