R & R Identification snap-on pipe markers are precoiled markers with arrows printed on them. Strap-on differ in that they are installed using ty-wrap type fastener.

R & R Identification uses only the most durable inks for indoor/outdoor use. These markers are used on all pipes especially wet, cold, oily, or rusty pipes where pressure sensitive markers won’t stick. An adhesive strip is on the marker.

R & R Identification Snap-0n and strap-on pipe markers meet ANSI A13.1 standards.

To order stock markers simply decide on the size needed, quantity needed and stock number.

To determine the correct size marker, use actual outside diameter.

To order custom markers specify legend color and background color, the pipe diameter (including insulation) and quantity needed.
