An isolation tool (10) for isolating small bore pipe (P) has a spigot (12) having a proximal section (14) with diameter (D1) and a distal section (16) with smaller diameter (D2). A seal (18) is provided on the tool (10) around the smaller diameter section (16). In some embodiments, the isolation tool (10) is located through a hole (H1) in the wall of the pipe (P) and through a second hole (H2) in the opposite wall of the pipe (P), the tool (10) arranged so that when the tool is located through the second hole (H2) the seal (18) fills the bore (B) of the pipe (P) and isolates a section of the pipe (P). In other embodiments, the tool (10) may be located between severed pipe sections. |
