🔍 Key Concepts

• Safe gasket cutting practices when working on flanges • How to avoid damaging the flange face during gasket fitting • Why a gasket must match the flange surface for a proper seal

💭 Think About

• Which methods risk scratching, denting, or deforming the flange face and how would that affect sealing? • Which option produces a gasket that fits the flange accurately without striking or cutting the metal flange itself? • Think about standard shop practice: what tool or method is normally used to remove extra soft material (like gasket sheet) neatly and under control?

✅ Before You Answer

• Eliminate any choice that involves striking or cutting the metal flange face itself. • Ask whether the method allows you to clearly see and control how much gasket material is removed. • Consider which option aligns with good maintenance practice: preserve the flange, shape only the gasket.
