The Groove & Tongue faces of this flange should match each other. Out of them one of the flange face will have a raised ring (Tongue) which is machined onto the flange face while the other one is mating flange which has a matching depression (Groove) machined into it's face. Tongue-and-groove facings Flanges are available in both large as well as small types. They only differ in male-and-female types that is the inside diameters of the tongue-and-groove do not extend into the flange base, therefore retaining the gasket on its inner as well as outer diameters. These Groove & Tongue Flanges are mostly used on Valve Bonnets and pump covers. Tongue-and-groove joints have many advantage that they are self-align as well as act as  reservoir for the adhesive. General flange faces like the F&M, T&G and RTJ which can never be bolted together. The reason is that is those contact surfaces do not match each other and there are no gaskets that has one type on one side and another type on the other side.
