Piston Seals

Profile
Description
ETS

ETS

Double-effect Seals for piston, energised by an O-ring for dynamic applications. It features: low friction, no stick-slip and high wear resistance. Small size. Available in different coupled materials depending on the conditions of use.

ETG

ETG

Single-effect seal for piston, energized by an O-ring for dynamic applications. It features: low friction, no stick-slip and high wear resistance. Small size. Available in different coupled materials depending on the conditions of use.

ETU

ETU

Double-effect Seals for piston in critical applications (separation fluid/gas or low density fluids). The seal consists of a PTFE compound sliding block with a Q-Ring built-in on the sealing surface linked to an energising elastomer O-ring. It minimizes the phenomenon of stick-slip, ensures low friction and high wear resistance combined with a perfect degree of tightness. It can be used in applications compliant with ISO7425 standard.

ET/AP

ET/AP

Double-effect Seals for piston. Bi-compound sealing made of a sliding block linked to an energising elastomer O-ring. It features: low friction, no stick-slip, high wear resistance. Its small footprint is particularly suitable for low pressure operation. Available in different coupled materials depending on the conditions of use.

DHD

DHD

Double-effect Seals for piston with integrated anti-extrusion rings. Designed to provide excellent resistance in severe applications while minimizing the housing spaces. Thanks to the integrated anti-extrusion rings it allows large diametrical games. Particularly suitable for heavy hydraulic applications. Normally made ​​of compounds of PTFE with energizing rubber and anti-extrusion ring of polyacetal, it can be made ​​of different combinations of materials depending on the application.

ETO

ETO

Double-effect Seals for piston made ​​of hydrogenated polyurethane, energized by an O-ring for dynamic applications. It features: low friction, no stick-slip and excellent sealing effect even at low pressures, high seal effect and resistance to tearing and abrasion. Particularly suitable in pneumatic applications, it can be installed in applications compliant with ISO7425 standard.

OKS

OKS

Double-effect Seals for piston with energising elastomer element. Similar to ETS but particularly suitable for heavy-duty applications. Available in different coupled materials depending on the conditions of use.

OKES

OKES

Single-effect Seals for piston with energizing elastomer element. Similar to ETG but particularly suitable for heavy-duty applications. Available in different coupled materials depending on the conditions of use.

VSV

VSV

Seals supplied with profile for installation on piston or rod with mono-directional sealing effect. The seal is composed of a PTFE body containing an energizing metal spring. Available in different coupled materials of PTFE and spring materials according to the application. Also available in a special version with the spring covered with silicon compounds suitable and approved for use in the food and pharmaceutical industries.

VSO

VSO

Seals supplied with profile for installation on piston or rod with mono-directional sealing effect. The seal is composed of a PTFE body containing an energizing metal helical spring. Available in different coupled materials of PTFE and spring materials according to the application.
