Products

An outstanding product range - Trelleborg Sealing Solutions has the largest sealing product portfolio in the industry. With this and our engineered solutions, we can solve almost any sealing challenge. 

Standard Elastomers Seals

Wide range of elastomer sealing solutions

Our range of standard elastomer seals for hygienic applications extends from O-Rings, the most commonly used seal to flange gaskets specifically for pipe couplings, while our FlexiMold™ proprietary technology allows us to produce giant seals in almost infinite diameters. 

Standard O-Rings meeting challenging industry requirements

For static and slow dynamic situations, the O-Ring is the most commonly used seal, and Trelleborg Sealing Solutions can supply virtually any size. They are available to meet all international standards such as AS568B, DIN3771, BS 1806/ BS 4518, JIS B2401, NFT47-501, SMS 1586 and ISO 3601 alongside seals produced in custom dimensions. Cost-effective, our wide range of specialized elastomers means O-Ring material can be matched to the specific needs of an application.

FEP encapsulated O-Rings for higher chemical compatibility 

FEP O-Rings are an option when a seal with a higher level of chemical compatibility is required. These consist of an elastomer inner ring encapsulated within a seamless Tetrafluoroethylene-Hexafluoropropylene (FEP) sheath. The FEP outer layer gives chemical resistance similar to PTFE, while a core of either FKM or silicone provides elasticity. Compliant with FDA 21 CFR 177.1550 and 3-A standards, they are used in static, slow switching and rotary applications.

QUAD-RING® to avoid twisting in the groove

Trelleborg Sealing Solutions is the supplier of the original QUAD-RING®. This is a four-lipped seal with a specially developed sealing profile. In contrast to the O-Ring, the QUAD-RING® avoids twisting in the groove, has improved friction characteristics and gives higher sealing efficiency in some applications.

FlexiMold™ giant seals – excellent integrity without a dedicated tool

With FlexiMold™ proprietary technology, Trelleborg Sealing Solutions manufactures giant high quality seals. Of superior quality to those fabricated as spliced seals or from extruded cord, they demonstrate the full visual and dimensional integrity of a molded product. Produced without the need of a dedicated tool, a flexible tool setup minimizes leadtimes and costs. Available in a wide range of elastomers, FlexiMold™ is recommended for O-Rings and other seal profiles over 500 mm/20 inches. They are supplied to standards ISO 3601-1, AS568 and JIS B 2401 and can be produced in almost infinite diameters.

Kantseal with high extrusion resistance

The Kantseal is a static seal with a square cross section. The Kantseal offers high extrusion resistance, minimal deformation and a good compression set.

Flange gaskets specifically designed for hygienic pipe couplings in process systems

Trelleborg Sealing Solutions has a range of standard flange gaskets specifically designed for hygienic pipe couplings in process systems. The gaskets are available in premium materials, and their excellent chemical resistance helps reduce downtime, improving production efficiency by extending seal life. They also minimize the risk of contamination and bacterial ingress, ensuring product purity.
Parts are available in both inch sizes according to ISO 2852 and metric sizes to DIN 32676.

Dynamic Linear Seals

A leader in fluid sealing
At the forefront of product design for fluid sealing situations, Trelleborg Sealing Solutions provides an unrivalled range of proprietary seals for dynamic linear applications. Our range of products is one of the broadest on the market, satisfying specific needs.
 
In addition to the three seals mentioned above, the fluid sealing range also includes the products Rimseal, L-Cup®, U-Cup, VL-Seal, Double-Delta®, AQ Seal® and Wynseal® .
 
Turcon® MF: the ideal material for hygienic applications
 
All fluid seals can be manufactured in Turcon® MF materials, which are specially engineered for aseptic applications. These compounds, with their compliance to all major approvals and almost total chemical compatibility, allow these geometries to be fully utilized in food and beverage applications.

Static Hygienic Seals

Specialized static seals for hygienic-design couplings

Filling equipment, processing and packaging machines consist of many parts that have to be connected together. Proper cleaning, usually Cleaning-in-Place (CIP) followed by Sterilization-in-Place (SIP) can only be achieved with hygienic design of the connection.

Gaskets and O-Rings in specialized materials

Trelleborg Sealing Solutions offers gaskets and O-Rings for the most common standards that apply to hygienic-design couplings, such as ISO 2852, DIN 11864 and DIN 32676. They are available in EPDM and FKM materials specifically engineered for hygienic-design coupling applications.

Proven outstanding performance in tests

The three materials recommended for hygienic-design couplings, EPDM E7502 and FKMs V8605 and V8T41, underwent various tests, including immersion in 21 commonly used CIP fluids. The materials demonstrated outstanding performance with V8T41 giving exceptional results for a fluorocarbon sealing material. In addition, the material is also suitable for hot water and steam applications up to +170°C / +338°F.

Compliant with major standards

All of these materials are compliant to and tested against FDA, 21 CFR177.2600, 3-A, USP Class VI, as well as against cytotoxicity (USP and DIN EN ISO 10993-5) and conform to regulation (EC) 1935-2004.

Dynamic Rotary Seals

Specialized high performance rotary sealing products
When it comes to successfully sealing in rotary applications, specialized products are required. Trelleborg Sealing Solutions offers a range of unique options, both standard and custom, that give exceptional performance characteristics in demanding rotary situations.

Turcon® MF: the ideal material for hygienic applications

Rotary seals can be manufactured in Turcon® MF materials, which are specially engineered for aseptic applications. These compounds, with their compliance to all major approvals and almost total chemical compatibility, allow these geometries to be fully utilized in food and beverage applications.

Engineered Seals

Engineered seals broaden application coverage
Custom designs provide the optimum solution

For some critical applications, the best solution is a custom designed component, where material knowledge and a high level of technical design are united. The Trelleborg Sealing Solutions portfolio of engineered products is almost unlimited. This allows us to meet our aim of developing the optimum solution for each application, in terms of both value and functionality.

From simple product variations to complex gaskets

The product offering includes anything from relatively simple variations on a standard seal designs to diaphragms, with or without fiber reinforcement and complex gaskets. Sealing elements can also be bonded to housing substrates such as plastics or metal. These give almost total integrity, minimizing assembly, reducing overall production costs.

Scrapers

Scraper ASW in white Polyurethane

Scraper ASW is single-acting and available machined in white Polyurethane. The 95 Shore A material, WUAW5, is fully FDA approved and compliant with European Regulations (EC) 1935/2004 and (EU) 10/2011. Mounted front flush there is no annular depression, preventing collection of pharmaceutical powder or food particles. When the rod is removed it can, if necessary, be disassembled for cleaning and reassembled easily.

Supporting customers in proving custom designs

Working with customers to prove seals in application in our global research and development centers and test facilities, numerous tests can be carried out to make sure compounds perform to specific requirements. Additionally, using tools such as Finite Element Analysis (FEA), we can prove seal behavior in application in a virtual environment. While leading-edge test facilities, mean we can validate designs in a laboratory situation before the customer performs their field tests.
