CarcoTex SP/SG

The CARCOTEX / SP / SG piston seal kit is a canopy textile-rubber seal for very heavy duty applications where a full rubber sealing element is used instead of a pressure ring. Due to this design, the sealing kit is mounted in the axial clearance housing, is not adjusted by compression and has excellent tightness. Due to the extremely robust construction, this seal can also withstand large radial shocks and high pressure peaks. Typical use is as a piston rod seal on heavily loaded hydraulic cylinders in machines such as forging or extrusion presses.

The set always consists of:

● One all-rubber sealing ring, which has optimum mechanical properties and provides excellent tightness over the entire pressure range.
● One or more solid textile-rubber sleeves of "V" cross-section.
● A retaining ring reinforced with Kevlar fabric, with extreme resistance to extrusion.


The CARCOTEX / SP / SG seal is designed into a fixed housing in which it has axial clearance. The preload required for the proper operation of the CARCOTEX / SP / SG seal kit is provided by the all-rubber sealing ring located first in the kit. This is followed by a solid textile-rubber cuff and a Kevlar reinforced retaining ring. As the pressure increases, the sealing set is further activated, ensuring its trouble-free operation.
The kit contains multiple sealing blades, ensuring a quality seal. For this reason, CARCOTEX / SP / SG kits are usually supplied split (SPLIT), which greatly facilitates and speeds up seal replacement, reduces machine downtime and thus significantly reduces repair costs.
