Mueller Streamline a 18567u 1/4 in Flare Ball Valve

Product Description

The MUELLER STREAMLINE a 18567u is a 1/4-inch female flare x male flare ball valve designed for shutoff and flow control in refrigeration and HVAC line sets. Ball valves in this configuration provide a full quarter-turn operation that opens or closes the flow path quickly and reliably, reducing leak points in flare-connected tubing systems. This valve is a standard trade component installed by licensed HVAC and refrigeration technicians during system commissioning, service, and recovery procedures.

This ball valve is suited for use in residential and light commercial HVAC and refrigeration systems where flare fittings are the connection standard. The female flare inlet and male flare outlet allow direct in-line installation on copper line sets without the need for additional adapters. It is commonly installed on suction and liquid lines, service ports, and recovery equipment connections where a secure, leak-free shutoff is required.

Key Features

• 1/4-inch female flare x male flare configuration for direct in-line installation
• Full quarter-turn ball valve operation for fast, positive shutoff
• Flare connections eliminate the need for solder joints at this fitting
• Compact design suited for tight equipment access areas

Compatibility

Designed as an OEM-style replacement or service valve for residential and light commercial HVAC and refrigeration systems using standard 1/4-inch flare connections.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician following applicable local codes and EPA Section 608 refrigerant handling regulations. Recover all refrigerant and depressurize the system before disconnecting or replacing any line-set components. Use a flare wrench on both fittings to avoid rounding the flare nuts, and inspect flare seats for damage before making connections. Do not overtighten flare connections; verify the assembly is leak-free with an electronic leak detector or nitrogen pressure test before returning the system to service.
