Hygienic Clamp Seals
Freudenberg has developed clamp seals for simple and secure pipe connections with a wide range of applications in the food and beverage industry. They are the ideal sealing element for flange connections that have to be opened regularly. The five available approved materials, EPDM (black), EPDM (white), Fluoroprene XP (light blue), VMQ (transparent) peroxide cross-linked and VMQ (transparent) platinum cross-linked, offer good resistance to water, acids, fatty and aqueous media and prevent aroma transfer. Easy handling and high operating performance are further advantages of standardised clamp seals. On request, the clamp seals are also available without an outer lip.

Freudenberg Sealing Technologies has developed clamp seals as an innovative solution for simple and secure pipe connections, catering to a wide range of applications in the food, beverage, and pharmaceutical industries. These seals are particularly suited for flange connections that require regular opening, ensuring both reliability and ease of use. Designed to meet industry standards, clamp seals are dimensionally standardised according to DIN 32676, making them economical and readily available from stock. Their standardised design also facilitates easy installation and handling, contributing to high operational efficiency in continually operated equipment.
The clamp seals are available in five high-performance materials: EPDM (black), EPDM (white), Fluoroprene® XP (light blue), VMQ (transparent) peroxide cross-linked, and VMQ (transparent) platinum cross-linked. Each material offers excellent resistance to water, acids, fatty and aqueous media while preventing aroma transfer—a critical requirement in food and beverage applications. These materials comply with international approvals and certifications, ensuring safety and compatibility with industry standards.
Freudenberg’s clamp seals also provide flexibility in design. While the standard versions include an outer lip for enhanced sealing performance, they can be customised to exclude the outer lip upon request. This adaptability makes them suitable for diverse operational needs across different equipment setups. The seals are not only robust but also versatile enough to handle nonhazardous media applications.
In addition to their superior material properties, Freudenberg clamp seals stand out for their ease of assembly and elasticity. Their efficient design minimises downtime during maintenance or cleaning processes, which is essential for industries requiring frequent system access. Furthermore, Freudenberg offers aseptic O-rings as an alternative for hygienic pipe connections when dead space elimination is crucial. These O-rings combine easy mounting with high-performance materials tailored for hygienic design requirements.
