Sanitary Tri-Clamp® Fittings - Sizing and Introduction
Schematics are designed to eliminate sizing errors when specifying sanitary fittings. The fitting outside diameter is the same for 1/2" and 3/4" ID 'mini' styles. This is also true for the 1" ID and 1-1/2 ID sizes. Note the inside diameter (ID) to properly mate with existing equipment/gaskets.
