Alwin Höfert KG products

These micro precision O-rings are designed to meet the demanding requirements of various industries, adapting to the specialized needs of sectors such as micro-electronics and micro-medical technology. With applications in medical instruments, fine mechanics, IT systems, micro switches, chronographs, and tachographs, these O-rings are crucial for high-precision equipment. They are produced in standard sizes starting as small as 0.50 x 0.30 mm, emphasizing quality and precision. The manufacturing process ensures uniform shaping, high cleanliness in deburring, and extremely fine tolerance values through advanced production methods and meticulous final inspection. Since 1963, Alwin Höfert KG has been committed to producing O-rings and specialized seals that exemplify German-made quality, promising reliability and technical perfection for precision products.

FEP-encapsulated O-rings from Alwin Höfert KG are designed for industries requiring enhanced chemical resistance and durability, such as the chemical, petrochemical, pharmaceutical, and food sectors. These O-rings comprise an elastic core made of Viton® or silicone elastomers, which is seamlessly enclosed in a thin-walled sheath of fluorinated ethylene propylene (FEP). The thickness of the FEP sheath is determined by the inner diameter and cross-sectional thickness of the sealing ring. Available in cord sizes ranging from 1.5 mm to 19.0 mm, these O-rings ensure the required elasticity through their core materials while delivering exceptional chemical resistance thanks to the FEP covering. This combination provides exceptional sealing performance even under harsh conditions, ensuring reliability in various industrial applications.
