Lap Joint Stub End
MSS (Manufacturers Standardization Society) and ASA (American Standards Association) are two different standards organizations that have developed standards for pipe fittings. MSS and ASA stub ends differ in their dimensions and tolerances. MSS stub ends have thicker walls and larger flanges than ASA stub ends, which makes them better suited for high-pressure applications. ASA stub ends are typically used for low-pressure applications.
