SYSTEM #4 PIPE MARKERS™ (High Temp Markers)
These markers are designed to withstand harsh chemicals, abrasion, and weather all environments. The printed legend is laminated between two layers of polyester, creating an extremely DURABLE product.
- UV Printed legend is laminated between two layers of polyester, creating an extremely DURABLE product.
- These Markers are available in 2 ways, markers that Wrap Around pipe and markers that are laminated to Black Carrier (Strap On).
- For pipe diameters 1/2" thru 7-7/8" use Wrap Markers (Styles 4A, 4B, 4E, 4F) these markers will wrap around pipe and are secured in place by an overlapping clear adhesive strip.
- For pipe diameters 8" or larger use Strap On Markers (Styles 4G & 4H) these markers are laminated to a heat and chemical resistant carrier that is then strapped on to pipe with nylon ties or stainless steel strapping.
- Durability: 5 to 8 years outdoors
- Service Temp: -40° to 248° F
- Minimum Application Temp: None
- Spec Compliance: ANSI / ASME A13.1 2015
MARKER SIZE, LETTER HEIGHT & MAX. CHARACTERS PER MARKER CHART
The following chart shows the recommended pipe marker letter height and marker size based on the outside pipe diameter of the pipe to be identified. For pipes smaller than 3/4" and for valve identification, the use of a permanent legible tag is recommended.

|---|---|---|---|
| 1/2" to 1" | 1/2" | 4A | 22 |
| 1-1/8" to 2-3/8" | 3/4" | 4B | 18 |
| 2-1/2" to 4-3/4" | 1-1/4" | 4E | 22 |
| 5" to 7-7/8" | 1-1/4" | 4F | 22 |
| 8" to 10" | 2-1/2" | 4G | 22 |
| Over 10" | 3-1/2" | 4H | 16 |

Colors:
The secondary means of identification is the color code of the marker. The exact colors are contained in the ANSI Z535.1 Safety Color Code.
Color is the secondary means to identification but many times the most important. The color of the marker should be used to identify the characteristic hazard of the contents of the pipe. The following chart list the classifications shown by ANSI / ASME A13.1 2015 as the suggested color combinations for the pipe markers.

Installation Recommendations:
 Install pipe labels close to valves or flanges
|
 Install pipe labels near branches and whenever a pipe changes direction.
|
 Install pipe labels before and after all wall, floor and ceiling penetrations
|
 Install pipe labels at frequent intervals on straight pipe runs.
