Abstract
A pipe marker imprints a double mark on a copper pipe used for heatless or torchless copper pipe connection in HVAC and refrigeration systems applications, such that the distance from any point between the double mark to the end of the pipe is sufficient to be inserted into the coupler for a strong, leak-proof connection between copper pipes. The pipe marker accommodates different diameters of the pipe and imprints the double mark at the correct location on the pipe based on the diameter.

A pipe marker comprising:
- a pipe marker assembly comprising a front, a back, a top, a pair of opposite sides;
- an elongated chamber disposed inside the pipe marker assembly, the chamber comprising an inlet disposed on the front and a wall near the back, the chamber configured to receive a pipe comprising an end and a diameter through the inlet and position the end abutting the wall;
- a spring loaded down facing double blade configured to imprint a double mark on the pipe, such that the distance between any point between the double mark and the end is no less than a critical distance corresponding to the diameter.
