Blue 2-1/2" Double Jacket Discharge Hose (NPSH) Aluminum

Applications For Blue 2-1/2" Double Jacket Discharge Hose NPSH Aluminum Fittings

The double jacket polyester discharge hose has a working pressure of 250 PSI making it tough enough for most users.  It's constructed from the same material as fire hose and has a wide variety of industrial & residential applications.  Users most often choose standard discharge hoses over fire hoses for the cost savings since most users will not be using hoses for fire fighting purposes.  Discharge hoses aren't certified for firefighting.  Use it for all other applications:

• Heavy Industrial Projects (Irrigation • Construction • Chemical • Oil • Manufacturing • Washdown)
• Residential & Commercial (Fire Hydrants • Water Pumps • Drainage • Standpipes • Testing)
• Special Industry (Marine • Shipping • Mining • Military • Drilling • Decontamination)
• Government (Military • Infrastructure • National Parks)

Specifications

Compatibility Overview

NPSH stands for National Pipe Straight Hose.  NPSH is a straight pipe thread which will fit onto most pipe standard pipe threads.  It's a very common fitting in USA industry.  When dealing with NPSH, you should remember a few simple rules:

• NPSH female will fit onto any male pipe threads including: NPSH • NPT • PVC • IPT
• NPSH male will fit onto straight female pipe threads including: NPSH • PVC • IPT
• NPSH male will not fit onto tapered female pipe threads including:  NPT

Polyester Material Advantages

• Polyester discharge hoses never need drying and can be stored wet.  They are 100% immune to mildew and rot and can be stored for extended periods of time.
• Treated polyester material handles abrasion extremely well.  Hoses are suited to be deployed and rolled up daily without needing constant replacements.
• Polyester hoses have no toxic chemical exposure as opposed to PVC plastic hoses which contain high amounts of water contaminants.  Keep your communities free of unnecessary chemicals.
• Lightweight, flexible, strong, and kink resistant are the best attributes of using polyester hoses.
• Aluminum hose couplings are lighter than brass and 3x stronger and highly anti-corrosive.

Differences Between Single & Double Layered Discharge Hoses

The difference between single and double jacket hoses is the layers.  Simply put, double the layers means double the strength and double the lifespan.  Single jacket hoses contain a single layered polyester jacket with a rubber liner, and a double jacket hose has an extra layer of polyester pulled over it making it double the thickness.  Both have their advantages. 

• Single jacket discharge hoses are suitable when you need a lighter weight and more economical hose that can still handle tough jobs.  The working pressure is 150 PSI which can handle regular street pressures.
• Double jacket discharge hoses are built for long term heavy abrasion.  They have double the life of a single jacket hose and have a great working pressure of 250 PSI. 

Spray Nozzle Compatibility

The 2-1/2" hose size is compatible with 2-1/2" spray nozzles or 1-1/2" nozzles when adapted down.  Whether you're doing industrial wash down or special purposes this hose is compatible with all types of nozzles.  Typical spray nozzles are made with 1-1/2" NPSH (straight pipe) or NH (NST) threads, and will fit directly onto the male end of the discharge hose.  Refer to the chart below for a list of commonly manufactured nozzles.
