We manufacture a vast range of Tinned Screw Sleeves to meet the material and dimensional specifications laid by different international standards. Brass line taps are made with high tensile brass as per BS 2874 - CZ112. Threads are formed by railing process giving the nut extra clamping force. Pressure pads are made from extruded bar (not cast), preventing the pads from cracking. Brass line taps are manufactured in passivated natural brass with electro tinned finish. They are also supplied in high conductivity copper.
