Lennox 40L64 Hose Barb
For field technicians and contractors maintaining Lennox industrial air conditioning and refrigeration equipment, the Lennox 40L64 Hose Barb is an essential OEM replacement part engineered for high-integrity fluid system connectivity. This brass hose barb is constructed from rugged cast brass, ensuring superior resistance to corrosion and mechanical stress in harsh environments. Designed with a 3/4 inch MPT (Male Pipe Thread) on one end and a 1/2 inch barb on the other, it facilitates a secure, leak-proof transition from rigid piping or pressure regulators to flexible 1/2" ID tubing. Rated for temperatures up to 200°F and pressures up to 150 PSI, this fitting is optimized for critical applications such as condensate drain lines, refrigerant pressure regulation, and pressure gauge tap-ins within indoor evaporator coils and discharge lines. The precision-spiked barb design provides a reliable grip that prevents disconnection under thermal expansion, making the Lennox 40L64 a dependable choice for maintaining system pressure and fluid control across commercial furnaces and heat pumps.
Key Benefits- Universal Compatibility: Engineered as a direct replacement for legacy part numbers including 98G50, 13H23, and 40L6401PR.
- High-Pressure Seal: Precision threads and barbed ridges ensure a leak-proof connection without the essential need for supplemental sealants in many standard applications.
- Industrial Durability: The heavy-duty brass body provides exceptional heat and vibration resistance, outperforming standard plastic fittings in high-cycle HVACR systems.
- Versatile Application: Suitable for a wide range of media including water, air, and refrigerant fluids, compatible with aluminum or copper tubing setups.
What is the nominal size for the Lennox 40L64?
This part features a 3/4 inch MPT nominal connection designed to mate with standard NPT threaded ports, transitioning to a 1/2 inch hose inner diameter.
Can this hose barb be installed in a vertical orientation?
Yes, its robust brass construction and grip design allow for secure operation in both vertical and horizontal orientations without compromising flow or seal integrity.
Is the 40L64 resistant to chemical corrosion from condensate?
Since it is manufactured from high-quality brass, it is naturally resistant to the mild acidity often found in air conditioning condensate and various industrial fluids.
