Product Description

Product Description

The AQF profiles is a advanced hydraulic seal. It utilizes a low-friction PTFE ring as the primary sealing face. This PTFE element is energized by a separate elastomeric star-ring, which provides superior sealing force compared to a standard O-ring. Two additional guide O-rings ensure stability and prevent extrusion in high-pressure applications. They can be assembled in grooves according to standard ISO 7425/1. Option of connecting the seal to 1 or 2 back-up rings.

Design Standard

The series is in conformity with ISO 7425/I, GB/T15242.1 and GB/T15242.3
