PART NUMBER ANALYSIS

To properly select or replace this material

What Sets This Material Apart

The EPDM binder must be evaluated for compatibility with chemicals and oils. Garlock specifies precise bolt load requirements for steam applications.

Recommendations for Replacement Analysis

Prioritize the operating service and actual media before considering gasket dimensions. Do not select 3700 for hydrocarbon service solely based on published temperature limits.

To differentiate binders and formulations: Garlock High-Temp 5507 and TEADIT NA1085. The binder systems and fibres are not identical. This comparison is intended to highlight technical distinctions, not to establish direct equivalence.
