Compression Fittings

Compression fitting is the general term for a pipe used to indirectly help connect one part to another. Compression fittings also have names such as joints and connectors. They are used to connect pipes and hoses. There are types that enable single-action attachment of the fitting end. They are known by names such as quick couplings. Black screw-in fittings are often used in standard pipes. Stainless steel fittings are highly corrosion-resistant, suitable for outdoor use. Fittings with inserts improve part strength and durability. Besides stainless steel, compression fittings are made of materials such as brass and alloys (65% copper and 35% zinc). The right compression fitting for the application should be selected by considering factors such as material, shape and type.
