White 2" x 50' Single Jacket Hose (Alum NPSH Couplings)

Single jacket hoses are never used in the fire service.

How To Purchase Fire Hose

• Always ask where the hose is manufactured - Buy American!
• Adding color impregnation improves durability compared to untreated white hose
• 50 foot lengths are easier to handle and offer more layout flexibility vs. 100 foot lengths
• The most common hose, thread and couplings in use by fire departments today is double jacket hose with aluminum NH / NST
• Double jacket hose with any color is the most durable hose available

Applications

• Forest firefighting
• Brush firefighting
• Residential Use
• Wildland firefighting
• Light Industrial Use

Test Ratings (Water Only With Expansion Ring Couplings)

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

NPSH Threads

• 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.

Hoses with National Pipe Straight Hose Thread (NPSH or NPS) has the same threads per inch (TPI) as National Pipe Thread (NPT) but the threads do not taper. This allows a female coupling to thread onto a NPT fitting without being a permanent connection. For example, a female fire hose coupling with NPSH threads will only connect to a PVC pipe, metal pipe or couplings with NPSH or NPT threads. Fittings that are connected together by NPT by NPT require a sealing agent like pipe cement or teflon tape because the threads are making the seal and a permanent connection. When a female NPSH is threaded onto a male NPT fitting, it allows this connection to thread on and off frequently by using a gasket to seal.
