Advantages of standard compression fittings
Though the simplest of pp compression fittings , the standard fitting does its job perfectly well. When all that is required is the joining of tow lengths of pipe, a standard pp compression fitting is totally suitable. There is no advantage in making the connection more complicated than it needs to be.
The biggest advantage standard couplings have over flared compressions is thanks to their simplicity and the requirement of one ring and one nut, fitting is straightforward and can be installed with the minimal of tools and fuss to achieve a satisfactory result. Most standard compression fittings can be completed with standard tools, such as a wrench to tighten the nut. They do not require soldering and can be completed by non-professionals. This also means that a standard fitting is much faster to complete than a flared fitting.
