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 encapsulated 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® Seal/X-Ring to avoid twisting in the groove
The Quad-Ring® Seal/X-Ring is a four-lipped seal with a specially developed sealing profile. In contrast to the O-Ring, the Quad-Ring® Seal 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 lead times 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 square rings with high extrusion resistance
The Kantseal square ring 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, including HMF48, 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.
Parts are available in both inch sizes according to ISO 2852 and metric sizes to DIN 32676.Parts are available in both inch sizes according to ISO 2852 and metric sizes to DIN 32676.
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.
Turcon® Glyd Ring® with improved leakage control Turcon® Glyd Ring® and Turcon® Glyd Ring® T give excellent leakage control in piston and rod applications along with resistance to extrusion.
These double acting O-Ring energized seals are primarily for dynamic applications where they give high wear resistance. Their low friction characteristics give long life and prevent sticking even after extended periods of rest. Typical applications are high performance piston fillers and metering pumps for very viscous fluids.
Turcon® Stepseal® enhances performance in cylinder applications
Achieving new levels in piston and rod sealing, the Turcon® Stepseal® 2K enhances efficiency in these applications.
With excellent extrusion resistance, it gives superior leakage control. It also has uniform, low friction characteristics throughout an extended life, and sticking is prevented, even after long periods of rest. With very good abrasion resistance, this seal is a good choice for sticky fluids such as syrups and in glues.
Turcon® Variseal® for optimum aseptic sealing
Turcon® Variseal® is an extremely important product within bioprocessing, food, beverage and pharmaceutical production. Commonly installed in filling plants, where demands are high on cleanability, sterilization and hygienic design, it is field proven in such operating conditions. Designed to fit in existing O-Ring grooves, it can provide a very high level of integrity, even in aggressive system media and within cleaning regimes.
For static and dynamic applications, these seals demonstrate low-friction characteristics, leading to extended service life.
The Zurcon® Scraper ASW is single-acting and available machined in white Polyurethane. 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.
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® Roto Variseal®, with its V shaped ring, has a flanged heel which prevents the seal from rotating in the groove.
Turcon® Roto Glyd Ring® is double acting and suitable for rotating, oscillating and helically moving pistons, rods and shafts.
Turcon® Varilip® PDR rotary shaft seals are constructed from one or multiple Turcon® PTFE based sealing elements which are mechanically retained in a precision machined metal body. The Turcon® sealing element provides positive dynamic sealing on the shaft, while the metal body gives a robust static seal against the housing, performing effectively at high rotary speeds. Characterized by low friction and stick-slip-free running, the seal reduces temperature generation, permits higher peripheral speeds and lowers power consumption. This results in a long-service life, with maximized mean time between planned maintenance and greater productivity.
Custom Engineered Seals
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.
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.
