Holyoke Fittings 48-48 Flare Male Adapter 1/4x1/2

Product Description

The HOLYOKE FITTINGS 48-48 is a flare male adapter designed to connect a 1/4-inch flare fitting to a 1/2-inch male flare connection. This type of adapter is a standard transition fitting used in refrigeration and HVAC systems where tubing sizes change between components or at service points. It provides a secure, leak-resistant flare joint suitable for refrigerant lines and similar fluid-carrying systems. HVAC technicians and refrigeration service pros use this adapter during system installation, repair, and component replacement work.

This adapter is typically installed in residential and light commercial HVAC and refrigeration systems. Common applications include connecting refrigerant lines between an indoor coil, outdoor condensing unit, or service valve where a size transition is required. The flare-style connection is well suited for field installations where a reliable mechanical joint is needed without soldering.

Key Features

• 1/4-inch to 1/2-inch flare male adapter configuration for size transition connections
• Flare-style joint provides a reliable, leak-resistant mechanical connection
• No solder required — field-serviceable connection suitable for refrigerant lines
• Compact adapter form factor for tight installation spaces

Compatibility

Designed as a standard flare male adapter for use in HVAC and refrigeration systems requiring a 1/4-inch to 1/2-inch flare transition connection.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician. Always recover refrigerant and depressurize the system before disconnecting or installing flare fittings. Use properly flared tubing ends and appropriate flare wrenches to avoid over-tightening, which can crack the flare seat. Follow all applicable local codes and EPA Section 608 requirements when working with refrigerant systems.
