Calibration pliers for piston seals

The calibration pliers are designed for the installation of PTFE piston seals. By means of the calibration pliers, the previously expanded seal is calibrated again to the nominal diameter in the groove. Can be used in the diameter range from 50 mm (1.97") to 360 mm (14.17"). The stainless steel belt is adjustable according to the dimension of the seals and the HPU triangle protection prevents damage to the seal during the pressing process.
