RTM1 100mm - 300mm O-Ring Inside Diameter Metric | O-Ring Inside Diameter 1095 Spring Steel Metric | Precision O-Ring Inside Diameter Tapes
Pi Tape® brand 1095 Spring Steel O-Ring Inside Diameter measuring tapes are suitable for use with all materials and in non-corrosive environments.
Pi Tape® brand Precision O-Ring Inside Diameter tapes are specifically designed to achieve quick, accurate inside diameter measurements of O-Rings and other soft-walled parts.
Tapes with a starting point of 2” (50.8mm) are made with a 1/4" (6.35mm) wide Gage Member and a 1/2" (12.7mm) wide Vernier Section. The standard thickness for 1/4" X 1/2" (6.35mm X 12.7mm) in Spring Steel, Blue Or White Easy to Read is .005" (0.13mm) and for Stainless Steel is .006” (0.15mm). Tapes with a starting point of 12” (300mm) are made with a 3/8” (9.53mm) wide Gage Member and a 3/4" (19.05mm) wide Vernier Section. The standard thickness for 3/8” X 3/4" (9.53mm X 19.05mm) all material is .010” (0.25mm).
- Standard O-Ring tapes have an accuracy of ± .003” up to 48” (± .09mm up to 1200mm)
- Standard O-Ring tapes starting between 48” -72” (1200mm-1800mm) and extended range tapes (tapes with over 12”/300mm of usable range) have an accuracy of ± .005” up to 72” (± 14mm up to 1800mm)
Each Pi Tape® brand precision measuring tape is furnished with a Calibration Report whose measurement results are traceable through NIST to the international system of units (SI). Not all items we calibrate are included in our scope, however the calibration techniques and procedures are all in compliance with ISO/IEC 17025:2017.
