Introduction
SD's flareless bite type fittings has a unique three-piece design having a body, a special case hardened ferrule and a nut. Unlike ordinary compression joints, when the nut is screwed on to the body, the ferrule grips the pipe in position and perceptibly bites in the pipe surface to provide a positive seal. When tightened fully the case hardened ferrule is bowed slightly in the middle and acts as a spring. This spring action of the ferrule maintains a continuous tension between the body and nut and prevents the nut from loosening under vibration and strain.

This unique function of ferrule is a result of careful selection of right materials, precision machining, and casehardening to give it a hard exterior and a soft core. The ferrule thus not only bites into the pipe readily and superficially without causing surface cracks, but also maintains its spring action for repeated use without loss of strength and sealing qualities.

SD flareless bite type fittings are manufactured to DIN 2353 standards making the fitting standard globally with the dimensions, materials and shapes the same making it acceptable all over the globe. These tube fittings also confirm to BS 4368.
