“Special, while supplies last” 6″ X 50′ Coupled Storz Supply Hose

Premium quality, light weight industrial fire hose, resistant to abrasion, chemicals and will operate in a broad range of temperatures. Ideally suited for fire fighting and other demanding industrial applications requiring layflat and flexible fire hose. This hose offers extended service life even after prolonged storage.

Pressure Ratings:

225# Service Test Pressure
450# Proof Test Pressure
675# Burst Pressure


Ozone resistant, nitrile black rubber tube and cover, with 100% synthetic yarn reinforcement. The “through-the-weave” extrusion process results in a one piece construction. This feature allows the hose to expand under pressure which decreases friction loss and increases water flow.

Temperature Range:

-30 degrees F to 122 degrees F

-34 degrees C to 50 degrees C

Special Characteristics:

Manufactured to meet or exceed NFPA specifications. All hose markings are per NFPA requirements. Stamped “Made in China”.


Today, virtually every fire department uses rubber lay-flat supply hose to move water efficiently. LDH

Hose is flexible hose designed for the purpose of moving water ( or flame

retardant ) between a pressurized water source and a pump that is supplying

attack lines. It may also be used to relay water from one pumper to another over

a long distance. Fire hose is generally considered to be LDH Hose when its

interior diameter exceeds 3½ inches; fire and departments in the United States

typically use LDH with diameters of 4, 5 or 6 inches.

LDH Hose is big-flow, low-pressure hose, which is both its defining feature and

the reason for its popularity. Because friction loss in fire hose is entirely

dependent upon flow, not pressure, the more capacity (GPM) a hose can carry,

the less force (PSI) is needed for the delivery.

This accounts for the ability of rubber lay-flat supply hose to deliver greater water volume, over greater

distances, with less friction loss than smaller diameter hose. With this capability

on their engines, firefighters are able to deliver big water to the fire scene with

• LDH Hose is generally longer than smaller diameter hose. Standard

lengths are typically 100 feet. Short lengths or pony lengths are used for

hydrant hook-ups to charge pumper units.

• LDH Hose is rugged, but not indestructible. Manufacturing techniques

include the extrusion of nitrile rubber in a Thru-The-Weave process or it

may be manufactured by laminating the nitrile rubber cover and liner. In

either case the entire length of the hose is seamless.

• LDH Hose is heavier than smaller diameter hose.

• LDH Hose plus water is very heavy. It is an accepted fire service

understanding that 5-inch LDH will hold 1 gallon of water per foot of hose.

With water weighing 8.33 pounds per gallon, a 100-foot section of 5-inch

LDH filled with water will weigh approximately 944 pounds.

Storz connections are hard-coated / anodized aluminum.
