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.
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.
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.
