The Brass Fittings category includes the precision-machined components that HVAC technicians rely on for reliable, leak-free and corrosion-resistant connections. Brass is widely used in refrigeration, condensate, plumbing and HVAC applications because of its strength, workability and resistance to pressure and chemical wear. Whether you are building a new system, replacing worn fittings or adding accessories, this section provides a complete lineup of OEM-grade brass connectors, adapters and valves that ensure long-term durability and performance.
You’ll find flare fittings, compression fittings, barbed fittings, threaded adapters, tees, elbows, couplings, caps, plugs, unions and service valves designed for copper tubing, condensate applications, refrigerant lines and general plumbing connections. Many fittings are HVAC-specific with proper flare angles, wall thickness, thread types and sealing surfaces that match industry standards. These fittings help prevent leaks, maintain refrigerant integrity and ensure safe system operation.
When choosing brass fittings, confirm tubing size (OD/ID), flare type, thread style (NPT, SAE), pressure rating, sealing method and intended application. Refrigerant lines require proper SAE 45° flare fittings, while condensate and plumbing lines typically use compression or threaded designs. Use the Compare tools on this page to review size, configuration and compatibility details before ordering.
Pro tip: Always clean tubing ends, ensure proper flare geometry, use correct torque and lubricate threads with appropriate refrigerant-safe products. These steps minimize leaks and extend the life of brass connections in HVAC systems.
Brass fittings include flare, compression, threaded and barbed connectors used for refrigerant lines, condensate tubing, plumbing connections and HVAC system service valves. Compare OD/ID size, thread type, pressure rating and fitting configuration for accurate selection.
