DIX Male Coupling 1 1/4" Brass

FEATURES:

• Male has octagonal facets for tightening with a wrench.
• The stem is expanded to nominal ID of hose for a rigid, uniform, full-flow area.
• Couplings are pre-lubricated for assembly.
• 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.

SAFETY NOTES:

• Do not interchange with other manufacturer's fittings.
• Designed for internal expansion only.
• Dixon Holedall stems and ferrules are specifically designed to be used together as a coupling system.
• Do not use a wrench or vice on ferrule
• Holedall couplings, regardless of coupling style, are never to be used for steam service at any pressure.
• Holedall fittings are not to be used with cable reinforced high-pressure hose, 4 or 6 braid wire hydraulic hose or any other service not listed in the recommendations.
• Strict adherence to ferrule OD range (Internally Expanded) for each hose end to be assembled is essential for satisfactory performance.
• Hose service working pressure (including surges and spikes) is never to exceed the maximum recommended working pressure for the fitting. The assembly's (hose + coupling) maximum working pressure is the lesser of the hose rated working pressure or the coupling rated working pressure.
• Media being transported through the hose should be compatible with the stem material. Compatibility of ferrule material with the environment in which it will be used is recommended.
