Brass internally expanded permanent coupling are recommended for discharge and suction service. Commonly used in the
transfer of fuel in industry to homes, airplanes, ships, etc. The working pressure of the 520-H fitting varies with the size of the
fitting, the size and construction of the hose and the media being conveyed. Consult the factory for recommendations. Dixon
Holedall stems and ferrules are specifically designed to be used together as a coupling system.
Both the male and female have octagonal facets for tightening with a wrench. The female in 1½" and larger sizes has special
lugs for tightening. The stem is expanded to nominal ID of hose for a rigid, uniform, full-flow area.
520-H Ferrules
• Male and female stems are machined from bar stock or
solid brass forgings; ferrules are available in brass and
stainless steel.
• Couplings are compact, light and streamlined to eliminate
catching on curbs and shrubs.
• The H520 fittings are designed for internal expansion only.
• Couplings are pre-lubricated for assembly.
• Hand and electrically operated installation equipment is
available. Consult factory for pricing and availability.

A wide range of 520-H ferrules permits a perfect assembly of a coupling to a corresponding size
of hose within commercial tolerances regardless of wall thickness. Eliminates need for large
stock of coupling bodies. Consult Dixon for other hose OD's.
1 1", 1¼" and 1½" ferrules will be replaced by API ferrules on page 14 as inventory is depleted.
