Product catalog summary
Overview
The UPOR covered precision O-Ring is designed for the chemical industry, offering high chemical resistance and pressure durability. It features an elastomer core for sealing pretension and a seamless FEP cover for resistance against aggressive substances.

Materials and Application Range
The O-Ring is suitable for use in chemical and food industries where aggressive media are present. It is not expandable and requires protection against mechanical damage.

Design and Surface Finish
Design hints include maintaining surface quality with specific roughness parameters (Ra ≤ 0.8 µm, Rt ≤ 3.6 µm) and groove dimensions (groove depth and width) for optimal sealing.

Installation and Usage
Installation is similar to standard O-Rings but requires careful handling to avoid damage to the FEP cover. It is used in environments with synthetic fluids, water-oil mixtures, and hydraulic oils.

Technical Specifications
Standard pressure and temperature ranges are up to 54 bar and -30°C to +200°C, respectively. The document provides detailed nominal and installation dimensions for various inner diameters and cord sizes.

Order Example
An example order for a standard version includes specifying the inner diameter and cord size, such as UPOR 50 x 3 for a 50 mm diameter and 3 mm cord size.

UPOR-1

Präzisions-O-Ring, ummantelt Precision O-Ring, covered Präzisions-O-Ring, ummantelt Precision O-Ring, covered Der ummantelte Präzisions-O-Ring UPOR wurde für die speziellen Anforderungen der chemischen Industrie konzipiert. The covered precision O-Ring type UPOR was developed to meet specific requirements of the chemical industry. Selbstverständlich findet er durch seine höchstmögliche chemische Beständigkeit und höchste Druckfestigkeit auch in anderen Industriebereichen Anwendung. Due to its high resistance to chemicals and pressure, it can also be applied to many other industrial fields. Er besteht aus einem Elastomerkern für die Vorspannung an der Dichtstelle und der vollständig nahtlosen Ummantelung aus FEP, welche die Abdichtung und Beständigkeit gegenüber aggressiven Substanzen sicherstellt. It consists of an elastomer core for the pretension of the joint to be sealed, and a seamless cover of FEP which provides resistance to aggressive substances.
