PART NUMBER ANALYSIS

To properly select or replace this material

What Sets This Material Apart

The perforated stainless steel insert reinforces the mechanical strength of the PTFE sheet. This material is not simply GYLON 3500 with a different pressure rating.

Recommendations for Replacement Analysis

For high-pressure service, evaluate the flange class, bolt loads, and mechanical design. Garlock recommends a technical consultation for certain higher-class assemblies.

To compare constructions: Garlock GYLON 3500 and Garlock GYLON HP 3561. These sheets use a silica-based filler, but their structure, creep resistance limits, and installation procedures may differ.
