components are the industry standard with
versatility of design and high reliability for
low maintenance, installation and inventory
costs. Standard FKM gaskets, seals and
boots, and a zinc die cast enclosure provide
exceptional chemical resistance to the
common coolants, cleansing agents, and
hydraulic fluids found in machine tool,
automotive, waste water treatment and other
heavy-duty industrial applications. Mounting
dimensions accommodate both U.S. and
DIN standards for easy retrofit installations.
