Industrial sealing applications are becoming increasingly complex. Higher temperatures, aggressive media, compact designs, and stricter reliability requirements are pushing sealing systems beyond standard solutions.
To address these challenges, our product portfolio covers a wide range of sealing geometries, from standard o-rings to highly customized sealing elements, supporting applications where geometry, material, and function must be precisely engineered.
This article presents an overview of our complete sealing portfolio, highlighting how we go beyond catalog products to support real industrial needs.
O-rings remain one of the most widely used sealing solutions due to their simplicity, efficiency, and versatility.
We manufacture o-rings from Øi 1 mm up to Øi 1750 mm, covering:
This wide dimensional range enables the use of o-rings not only in standard components, but also in large housings, flanges, and custom-designed equipment.
Beyond classic o-rings, the portfolio includes several modified and alternative ring profiles, designed to address specific functional requirements
Legenda sub-categorie PART
.D-RINGS
D-shaped rings, with internal or external flat profiles, typically used to improve stability in the groove or prevent rolling.
X-RINGS
Quad-lobe geometry designed to reduce friction and improve sealing efficiency in dynamic applications.
R-RINGS (KANTSEAL-type)
Internationally known sealing profile, used where higher stability and controlled deformation are required.
TR-RINGS (Trapezoidal Rings)
Trapezoidal cross-section rings, often used in demanding static applications where extrusion resistance and positioning are critical.
HEX-RINGS
Hexagonal cross-section rings (six-sided), niche geometries used in specific automotive or industrial designs.
OV-RINGS
O-rings with an oval cord cross-section (not an oval internal diameter), designed to optimize contact area and sealing behavior.
The portfolio also includes functional sealing components that go beyond ring-shaped seals
Legenda sub-categorie PART
.FRAME Seals
Complex-shaped seals typically used in housings and covers, often produced from custom drawings.
GROMMETS (Passacavi)
Sealing elements designed to protect and seal cables, tubes, or passages through panels.
B-RINGS (Back-up Rings / Stützringe)
Anti-extrusion rings used in combination with elastomeric seals to support high-pressure applications.
In addition to active sealing elements, we manufacture components designed for closure and protection
Legenda sub-categorie PART
.CAPS (“Tappi”)
Used to close ports, protect interfaces, or provide secondary sealing.
DISCS
Flat sealing or closing elements, often used where axial compression sealing is required.
A defining part of the portfolio is CUSTOM sealing solutions.
Any sealing element that does not fall into standard geometries—ring profiles, frames, or discs—is developed as a custom component, based on:
This approach enables the design and production of seals optimized for:
Rather than offering a simple catalog, the portfolio is structured to support:
From standard o-rings to large-diameter seals and fully custom profiles, the goal is to provide sealing solutions aligned with real operating conditions.
An updated product portfolio is not defined by the number of items it contains, but by its ability to solve real problems.
By combining:
our portfolio supports sealing reliability in applications where geometry, material, and performance must work together.
