PART NUMBER ANALYSIS

To properly select or replace this material

What Sets This Material Apart

The swelling action helps minimize fugitive leaks on low-rigidity flanges. Potable water compliance serves as an additional, distinct requirement.

Recommendations for Replacement Studies

Verify current certification, gasket dimensions, operating temperatures, and the water system specifications prior to substitution.

To evaluate alternative constructions: Garlock MULTI-SWELL 3760 and TEADIT NA1088. Swelling formulation and media compatibility must be verified against the exact grade data sheet.
