The Role of Compression Fittings in HVAC Systems
Compression fittings come in several types tailored to specific applications: straight, elbow, tee, bulkhead, and flare fittings, among others. Each type addresses particular piping configurations and flow requirements. For instance, elbow fittings enable directional changes, while tees allow branching of lines.
Material selection is crucial. Brass compression fittings are widely used due to corrosion resistance and machinability, suitable for water, air, and gas lines. Stainless steel fittings offer superior strength and chemical resistance, ideal for aggressive environments like chemical plants and offshore platforms. Plastic compression fittings, made from materials like PVC or CPVC, serve in applications requiring lightweight, corrosion-free connectors.
Ferrules may also vary in design and material, including single-piece or double-piece options, which influence sealing performance and reusability.
Understanding the operational environment and fluid characteristics is essential when choosing compression fittings, ensuring durability and leak-free connections.
