larger image
Brass internally expanded permanent couplings are recommended for discharge and suction service. Commonly used in the transfer of fuel 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 1 1/2" and larger sizes has lugs for tightening. The stem is expanded to nominal ID of hose for a rigid, uniform, full-flow area.
Features:
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.
Note:
The fittings on this page are intended for fuel delivery service.
Safety Alert: Do not interchange with other manufacturer's fittings.
