WHY BRASS FITTINGS
 
Brass is one of the most common materials used for making pipe fittings. Brass as a construction material is an alloy (primarily) of copper and zinc. Brass pipe fittings are in high demand because of some inherent properties which make them superior than other materials. Brass fittings are for carrying water, flammable gases, slurries, chemicals, fire sprinkler systems, etc. Pipe Fittings made of brass are available in a wide variety of shapes and thread sizes to connect, control or adapt any air or liquid flow in a pipe or tube.
 
Brass fittings are used in industrial and residential applications because they are strong and durable. The advantages of brass for fittings include its good corrosive resistance, and also its plating, joining, polishing and finishing characteristics. Brass as a material is easily machined and so can be given any shapes of the various types of fittings available.
 
Brass Offers Good Corrosion Resistance From Water and Heat and Resists Attack From Salt Water and Acids, Minerals and Peaty Soils Contained in Water.
   
Relative Softness of Metal Provides for a Tight Seal and Ease of Installation.
   
Brass provides a more solid platform (vs. plastics) to facilitate the flow of liquids and gas both in reduction and direction.
   
Brass fittings have excellent high temperature ductility and a reasonable cold ductility.
