Preassembly eliminates kits, saves on site labor2. Controlled assembly and pretesting eliminatesadjustments. Guarantees Mechanical design resists affects of stress andresulting insulation failure4.

2 Serviceability and maintenance greatly simplifiedDesigned to the highest possiblestandards including the following:Thicker dielectric sleeves (1/8") machined toprecise, close tolerance dimensions, bothlength and bolt holes line reamed to provideperfect alignment and close tolerancefit to the dielectric studs machined from Alloy Steel andheat treated to ASTM DesignationA-193-52T Grade B-7, resulting in superiorstrength and greater resistance to stressinduced nuts machined from Alloy Steel and heattreated to ASTM Designation A-194 Class machined steel washers, flat parallel, andcounterbored allowing for square alignment and clear-ance for the dielectric sleeves. The clearance preventsstress on the sleeves after torquing flange gasket precision cut for ideal fit withsmall projection into the stream to preventcontamination or bridging of the joint insidethe assembly with accurate torquingcarried out in stages followed by retorquingafter 24 for minimum resistance of 2,000,000ohms prior to packing in special gap sealed with epoxy resin toprevent contamination during postassembly handling.
