System #1 Pipe Markers™ Wrap Around & Strap On Markers
These markers are manufactured with rigid vinyl, their surface is printed with UV ink and then coiled. Coiled or wrap around a pipe markers are styles AA through E (pipes diameters from 3/8" through 6"). These markers are simply uncoiled by hand, and automatically recoiled around the pipe. Marker sizes C, D, E are supplied with a 1/2" wide strip of 3M™ 467 adhesive which only needs to be released when there is a constant pipe temperature of 100° or more.
Marker styles F through H (pipes over 6") are not coiled because of their size, they are installed using nylon ties. Style F is supplied with two 34" long ties, styles G and H are supplied with two 48" long ties. For pipes larger than 14" in diameter order additional nylon ties.
- These Markers are available in 2 styles, Coiled (Wrap Around) and flat with holes (Strap On)
- For pipe diameters 3/8" through 6" use Wrap Around Markers (Styles AA, A, B, C, D, E) these markers are simply uncoiled by hand and automatically recoil around the pipe.
- For pipe diameters 6" or larger use Strap On Markers (Styles F, G, H) these markers are installed using nylon ties or S.S. Strapping, Brimar supplies a pair of nylon ties with each of these markers.

Marker Size, Letter Height and Maximum Characters per Marker
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.

| 3/8" to 1/2" | 1/4" | AA | 20 |
| 3/4" - 1" | 1/2" | A | 22 |
| 1 1/2" - 2 | 3/4" | B | 18 |
| 2 1/2" - 7-7/8" | 1-1/4" | C, D, E | 22 |
| 8" - 10" | 2-1/2" | F, G | 22 |
| Over 10" | 3-1/2" | H | 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.
