Pipe marker visibility and size requirements
| Outside Diameter of Pipe or Covering | Length of Color Field | Letter Height |
|---|---|---|
| 0.7 in-1.3 in (18-33 mm) | 8 in (203 mm) | 0.5 in (13 mm) |
| 1.4 in-2.4 in (34-61 mm) | 8 in (203 mm) | 0.7 in (19 mm) |
| 2.5 in-6.7 in (62-170 mm) | 12 in (305 mm) | 1.3 in (32 mm) |
| 6.8 in-10 in (171-254 mm) | 24 in (610 mm) | 2.5 in (64 mm) |
| Over 10 in (Over 254 mm) | 32 in (813 mm) | 3.5 in (89 mm) |
What if your pipe or covering outside diameter is less than 0.7 inch or 18 mm?
In cases where it is difficult to label a pipe or covering due to size, we advise using durable and long-lasting energy source or valve tags in place of pipe labels or markers.
