Lennox 17W38 Service Valve
Proper refrigerant management starts with reliable hardware, and the Lennox 17W38 service valve is the industry standard for 3/8-inch liquid line applications. This OEM Lennox replacement part features a specialized 45-degree angled body, providing critical clearance in compact condenser cabinets where a straight valve would impede manifold gauge connection. Built from high-grade brass with a 1/4-inch flare fitting for service port access, the 17W38 is designed for precision front-seating and back-seating operations during system evacuation, charging, or isolation. Its 3/8-inch OD tubing connection ensures seamless brazing into the liquid line of Lennox residential heat pumps and air conditioners. Technicians rely on this valve to maintain system integrity and prevent refrigerant loss during routine maintenance. Whether you are performing a full system retrofit or a targeted HVAC valve repair, this component ensures leak-tight performance and long-term reliability in high-pressure environments. Stocking this 3/8-inch 45-degree service valve is essential for contractors who prioritize fast serviceability and factory-spec flow regulation.
Key Benefits
- Optimal Accessibility: The 45-degree offset simplifies connection in tight spaces, allowing for easier hose attachment without kinking.
- Secure Sealing: Features a high-integrity packing gland and stem cap to ensure a leak-tight refrigerant seal under extreme pressures.
- Universal Liquid Line Fit: Designed with standard 3/8-inch OD copper connections for broad compatibility across Lennox model lines.
- Precision Control: Integrated 1/4-inch flare service port allows for accurate pressure monitoring and efficient refrigerant recovery.
- Durable Brass Construction: Heavy-duty forged brass body resists corrosion and withstands the high temperatures of field brazing.
Common Questions
Is this a back-seating or front-seating valve?
The 17W38 is a dual-function valve that supports both front-seating (to isolate the outdoor unit) and back-seating (to open the service port) using a standard refrigeration service wrench.
Does this valve come with the service port cap?
Yes, this Lennox 17W38 includes the necessary caps to protect the valve stem and the 1/4-inch flare service port from debris and secondary leaks.
Is this part compatible with R-410A systems?
This valve is specifically engineered to handle the high-pressure requirements of modern R-410A refrigerant systems, as well as legacy R-22 configurations.
