Since 1901, Jefferson Union Company has been a leading manufacturer of malleable iron unions, specializing in elbows, tees and all-iron unions and continues to be a reliable source for Supply Houses nationwide. The vast majority of our standard products, and all of our special order products, are made in the U.S.A. This means we can get you these high quality unions, and meet your specialized requirements, in a timely manner.
Principally, our products fall into two major categories: Brass-to-Iron unions and Iron-to-Iron Unions (or All-Iron Unions as they are sometimes called). We offer these in a variety of sizes, and 150#, 250# or 300# PSI applications.
Jefferson can furnish any and all Unions and Convenience Unions in their complete line with either Brass Seat or Iron Seat. In the manufacturing process you cannot rely on the softness of brass to overcome inequalities in the machining, as is done by many makers of brass seat unions. All of our Malleable Iron unions are carefully machined by skilled workmen, the two end parts are ground together in pairs and assembled that way to assure a perfectly tight, leak-proof joint.
Under other conditions, Iron-to-Iron Seat Unions are highly recommended as giving superior satisfaction. They should always be used where the material being carried is injurious to brass.
Since chemical solutions are apt to contain impurities, blanket recommendations should only be used as a guide; but, subject to individual conditions, Iron-to-Iron Seat Unions are particularly suggested for the following:
- • Air
- • Alkalies
- • Mercuric Substances
- • Caustic Solutions
- • Copper Solutions
- • Asphalt
- • All Forms of Ammonnia
- • Sulfate Liquors
- • Chlorines (Wet)
