The Industry standard

The compression type fitting is extensively used because of its simplicity, efficiency, low cost and ease of assembly. Originated by Imperial Eastman in 1907, it has been one of the basic fittings for tubing connection work ever since for a wide variety of general service applications. Compression fittings marked with the Imperial Diamond “I” have become known as the finest of this type of fitting.

 

Easy To Assemble 

No flaring, soldering or other special preparation of the tubing is necessary before assembly. Simply slip the nut and sleeve over the tubing. (Ensure that tubing is cut square, and any burrs are removed before assembly)

Insert tubing into the fitting body until it rests against the shoulder. Move the sleeve into position and tighten the nut.

The accurate machining and liberal wall thicknesses accompany the sharp threads, all of which are clean ad true with the axis of the fitting.

 

Forged Bodies on Shapes

The elbows and tee bodies are made from brass forgings. The exceptional strength of forged fittings (over 80% stronger than brass castings) provides an extra safety factor. Extra toughness makes forged fittings stand up better under hard knocks, mechanical shock and vibration.

The extremely close grained structure of forgings assures against blowholes or other concealed defects and against seepage of hard to hold liquids and gases. Wrench flats and the greater uniformity provided by forgings facilitate quick, secure wrench grip and speed installation.

 

Applications

This fitting is widely used for connecting gasoline, grease, oil, water, vacuum and air lines and other medium and low pressure tubing connection where excessive vibration or tube movement is not involved.
