Rod Seals maintain sealing contact in sliding motion between the cylinder head and the piston rod. In addition to the sealing function, Rod Seals also provide a thin lubrication film on the piston rod which lubricates Rod Seal, Piston Seal and the Wiper Seal.
ZBR
Double lip U-cup profile made of polyurethane; suitable for heavy duty applications.
PTB
Polyurethane U-cup profile with incorporated nitrile rubber X-ring, which provides good performance even at low pressure and temperature.
SIL
SIL are made of etherbased TBU and have a double lip design. They provide good resistance to hydrolysis (attack from moisture) and good low temperature resilience.
DZ
Nitrile rubber primary sealing ring, polyurethane secondary sealing ring: low friction: suitable for heavy duty applications.
S1S
Single-lip U-cup profile made of polyurethane; suitable for heavy duty applications.
STD
Polyurethane U-cup profile with incorporated nitrile rubber X-ring, which provides good performance even in low pressure and temperature.
DZR
Nitrile rubber primary sealing ring, polyurethane secondary sealing ring, integrated triangular polyamide anti-extrusion ring: improved gap extrusion resistance; suitable for heavy duty applications and extreme pressures.
