The packing Style 2261 SAN offers excellent performance, especially in segments of equipment for drinking water, pulp and paper, food, chemical, pharmaceutical and sugar and alcohol.
Construction
Style 2261 SAN is a firm, pliable interlock braided packing manufactured from the purest ePTFE filaments. Style 2261 SAN is manufactured by an advanced method of braiding and construction from the purest ePTFE filaments.
Packing Style 2261 SAN also has proprietary food grade lubricant that provide faster break-in and reduced shaft wear. Style 2261 complies with the F.D.A. and U.S.D.A. requirements under Title 21 Food and Drugs:
- - Part 177.1550 - Perfluorocarbon Resins
- Part 177.2600 – Compliance for yarn
- Part 178.3570 - Lubricants with incidental food contact
Due to the technological edge of its filament that contains special additive encapsulated by pure PTFE, and his constructive feature offers excellent heat dissipation, which is usually generated by the sealing system. The result is its excellent sealability, particularly when compared with PTFE packings found in international markets.
