BellowsTech Products Company Overview

BellowsTechHHP Associates, Inc., a division of ESI, is the Florida representative for BellowsTech. BellowsTech is a proud member of the MW Industries family of companies, the largest and most diversified specialty spring, fastener and metal components manufacturer in the world.

BellowsTech is an edge welded metal bellows manufacturer. Metal bellows provide an all-metal pressure barrier and seal that flexes in one or more directions. Edge welded metal bellows provide the most flex in the smallest amount of space of any bellows technology on the market. With various materials and configurations, BellowsTech can achieve the pressure, temperature, and leak rate requirements that customers demand.

For more than fifty years, BellowsTech® has been receiving exceptional quality ratings consistently from its OEM manufacturing customers worldwide. BellowsTech® products are used in mission critical applications in aerospace, defense, medical, and oil and gas.
