KCP14775 - Curv-O-Mark Standard #6 Pipe Centering Tool

Precision Pipe Layout with the Curv-O-Mark Standard #6

The Jackson Safety Curv-O-Mark Standard Centering Head #6 (3001879) is an indispensable tool for professional pipe fitters and welders who demand accuracy in their layout work. Designed to eliminate the guesswork associated with finding centerlines and angles on cylindrical surfaces, this tool is a staple in the industrial piping industry. Its robust design and precise engineering make it the go-to choice for establishing cut lines, locating keyways, and setting points for welding supports.

Versatile Application Range

This standard model is specifically engineered to handle a wide range of common pipe sizes, accommodating diameters from 1/2 inch up to 4 inches. Whether you are working on small-bore instrument tubing or standard process piping, the #6 head provides a reliable reference point. The Y-shaped body is contoured to sit perfectly flush against the curve of the pipe, ensuring that the centering pin is always aligned with the true radius of the cylinder.

Integrated Angle Measurement

Beyond simply finding the top dead center, the Curv-O-Mark #6 features an integrated adjustable dial bubble protractor (DSL). This allows the user to not only locate the vertical center but also to measure and mark specific angles relative to the vertical axis. This feature is critical when laying out laterals, wyes, or angled supports. The dial is easy to read and adjust, providing a quick method for checking declivity and establishing precise angular relationships without the need for separate inclinometers or protractors.

Durability and Ease of Use

Constructed from high-quality materials, the body of the centering head is lightweight yet durable enough to survive the rigors of a fabrication shop or field site. The centering pin is made from hardened steel, ensuring it retains its point even after repeated use against carbon and stainless steel pipes. To use, simply place the tool on the pipe at the desired angle and strike the pin with a hammer to leave a clear, permanent mark for drilling or cutting.
