Due to supply chain issues brass couplings may be imported. If you require domestic couplings please call to place your order. There will be a surcharge and lead time is unknown. There is no change to the hose itself, which is woven and manufactured in the USA. We will switch back to U.S. manufactured couplings as soon as we are able.

Our 1 3/4 inch Made in the USA double jacket firefighting hose meets and exceeds all NFPA 1961 standards. Hose is stenciled and constructed to meet Mil Spec Mil-H-24606B used by the Navy, Coast Guard and other Military branches. This 24606 hose features brass couplings and orange abrasion impregnation.

This hose is constructed of an EPDM synthetic rubber tube and a double layer of 100% polyester woven jackets. The rubber lining is a single-ply extruded tube of synthetic EPDM compounded to resist ozone. Double jacket refers to the second layer polyester covering woven from staple polyester yarn added for increased abrasion resistance. NPSH / IPT threads are standard.

Mil-Spec Hoses are stenciled to include:

• MIL-H24606B
• Size and length of hose
• Service test pressure
• Month and year
• Manufacturer

Note: The most common 1 3/4 inch Mil Spec hose is coupled with 1 1/2 inch NPSH threads. Please verify thread type before ordering.

Test Ratings (Water Only With Expansion Ring Couplings)

• 300 PSI Service Pressure (A 3-minute hydrostatic test conducted by users on in-service hose to determine suitability for continued service)
• 600 PSI Proof Test Pressure (A pressure equal to a least two times the service test pressure)
• 900 PSI Burst Test Pressure

Applications

• Navy
• US Coast Guard (USCG)
• Military Branches

1 1/2" Hose Male Couplings

• Inside diameter of a male coupling: 1 1/2 inches
• Outside diameter of a male NH / NST coupling: 2 inches (1.99) - 9 Threads per inch
• Outside diameter a male NPSH or NPT coupling: 1 7/8 inches (1.87) - 11.5 Threads per inch

Note - 1 3/4 inch hoses come with 1 1/2 inch couplings

NH / NST: The most common thread type in use by fire departments today is NST or National Standard Thread. NST also goes by the initials NH or National Hose. It can even be referred to as NHT or National Hose Thread but NST or NH is more common these days. NH = NST.

• The female side of a NH / NST coupling will only connect to a male NH / NST connection
• The male side of a NH / NST coupling will only connect to a female NH / NST connection

NPSH: National Pipe Straight Hose (NPSH) or Iron Pipe Thread (IPT) has the same threads per inch (TPI) as National Pipe Tapered (NPT) but the thread does not taper. NPSH is a straight thread and seals by a gasket in the female coupling which allows for a swivel, just like NH / NST, which make both ideal for hose couplings.

• The female side of a NPSH coupling will only connect to a male NPT pipe or a male NPSH connection
• The male side of a NPSH coupling will only connect to a female NPSH connection
• It will NOT thread into a female NPT pipe. For example, a male NPSH coupling will NOT thread into a female metal or pvc pipe.

NPT: National Pipe Tapered is common in plumbing and some industrial uses. Sometimes referred to as pipe thread because PVC pipe and schedule 40 pipe are typically threaded in NPT. As its name implies this is a tapered thread so that the outside diameter of the male (ODM) gets smaller towards the end of the fitting and the inside diameter of the female narrows with depth. As the two fittings are threaded together the opposite tapers force thread friction and makes the seal without the use of a gasket.

Limited 10-Year Warranty

We will replace any fire hose with manufacturer defects in material and workmanship. All warranty claims must be returned to us for inspection before we determine a solution.

Our warranty does not cover gaskets, shipping cost, cosmetic damages, normal wear-and-tear, improper use or chemical damage.

Fire hoses purchased for use at Fire Training Facilities will have a 90-day Manufacturer Defect warranty only.

Upon receipt of the returned goods, hoses will be subject to inspection and testing.

Should it be determined that the hose is covered by warranty, it will be repaired or replaced.
