PROBLEM TO BE SOLVED: To provide a moisture-curable sealant composition for a piping which has a moderate hardness and is good in re-sealability. SOLUTION: The sealant composition for a piping comprises an organic polymer (A) containing a crosslinkable silyl group and a silane compound (B). The silane compound (B) is a dimethoxysilane having the structure represented by formula (1) and the content of the silane compound (B) is 0.5-18 parts by mass based on 100 parts by mass of the organic polymer (A) containing the crosslinkable silyl group. In the formula, R<SP>1</SP>indicates a 1-6C alkyl or vinyl group that may be branched; R<SP>2</SP>indicates a methyl group and the plural R<SP>1</SP>can be each the same or different.
