Hydraulics sealing
There are two ways to seal the flange contact surface (Fig. 7):
1. A sealing by using an O-ring (e.g. 22.4 × 2.65 mm (0.88 × 0.1 in.),
25.07 × 2.62 mm (0.99 × 0.1 in.)) in a cylinder end cap groove.
2. A sealing by using an O-ring in the undercut.
For threaded flange (¾"-16 UNF-3A) »F« / »S«:
O-ring 16.4 × 2.2 mm (0.65 × 0.09 in.) (part no. 560 315)
For threaded flange (M18×1.5-6g) »M« / »W«:
O-ring 15.3 × 2.2 mm (0.60 × 0.09 in.) (part no. 401 133)
Fig. 7: Possibilities of sealing
• Note the fastening torque of 75 Nm.
• Seat the flange contact surface completely on the cylinder mounting
surface.
• The cylinder manufacturer determines the pressure-resistant
gasket (copper gasket, O-ring, etc.).
• The position magnet should not grind on the sensor rod.
• The piston rod drilling (≥ Ø 13 mm (≥ Ø 0.51 in.)) depends on the
pressure and piston speed.
• Adhere to the information relating to operating pressure.
• Protect the sensor rod against wear.

In the case of threaded flange M18×1.5-6g provide a screw hole based on
ISO 6149-1 (Fig. 8). See ISO 6149-1 for further information.
