Supco sf8404 Line Service Valve 1/4 Inch Od Tube

Product Description

The SUPCO sf8404 is an economy line service valve designed for use with 1/4 inch OD copper tubing. The valve includes a plain cap and measures 2 inches in length. It is used by HVAC technicians to isolate refrigerant lines, perform system service, or take pressure readings on residential and light commercial refrigeration and air conditioning equipment. The compact design suits tight line-set installations where a low-profile valve is needed. Licensed refrigeration and HVAC technicians are the primary installers of this component.

This service valve is suited for refrigerant line applications using 1/4 inch OD copper tubing. It is commonly installed on suction or liquid lines in split-system air conditioners, refrigeration units, and similar equipment where field service access points are required. The included plain cap protects the valve port when not in use, helping to maintain a clean and leak-resistant connection between service intervals.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician holding the appropriate EPA Section 608 certification. Recover all refrigerant and depressurize the system before cutting or brazing any refrigerant line. Use proper brazing technique and flow nitrogen through the line during brazing to prevent oxidation scale inside the copper tubing. Pressure-test and leak-check the joint before recharging the system.
