Pi Tape RT2 | Precision Inside Diameter O-Ring Tape | 12–24 in I.D., 1095 Spring Steel
The Pi Tape RT2 reads O-ring inside diameters across 12–24 in with a stated tolerance of ±0.003 in; it is made in 1095 spring steel and reads in inches. It is intended for checking the inside diameter of O-rings directly, so ring size within the 12–24 in range can be confirmed consistently.
