- Nitrile Rubber Covered Hose Black LDH
- 4", 6", and 8"
|Temperature:||-5°F to 300°F|
Hose shall be made from 100 percent high tenacity synthetic yarn, circularly
woven and completely protected and locked-in by tough highly resistant synthetic
nitrile rubber, forming a single homogeneous construction without the use of
glues or adhesives of any type.
Ultimate Tensile Strength: Tensile strength of the lining and cover shall not be less than 1750 PSI.
500 percent minimum.
Accelerated Aging Test:
The tensile strength and ultimate elongation of the vulcanized rubber
compound which has been subjected to the action of oxygen at a pressure of 300
PSI (±10 PSI) and a temperature of 158°(±18°F) for a period of 96 hours
shall retain 60 percent of its originally stated properties.

Hose shall withstand 30,000 cycles on the Taber Abrasion
Machine (H-22 Wheel: 1 kg). Key Fire Hose Corporation on
request will supply written warranties that SUPER-FLOW
hose meets a minimum 30,000 cycles. Other abrasion test
results (UL, DIN, etc.) can be supplied on request of purchaser.
Hose shall have a capability of use down to -5°F. Hose shall
have no apparent damage to cover, reinforcement or lining
when subjected to the following cold bending test: a 50 ft.
length of dry hose is to be firmly coiled and placed in a cold box
at -5°F for a duration of 24 hours. Immediately after removal of
the hose from the box, hose should be uncoiled and laid out by
one operator. Following this procedure, the hose shall not leak
nor show any damage to the reinforcement when subjected to
the hydrostatic acceptance test stated above.
Hose shall show no visible signs of cracking to the lining
or cover when tested in accordance to ASTM D518
Procedure B, 100pphm/118°F/70 hours.
Exposure to sea water and contamination by most chemical
substances, hydrocarbons, oils, alkalis, acids and
greases must have no effect on the short or long term performance
of the hose. A chemical resistance chart is available
and Key Fire Hose will supply specific chemical resistance
data on request of purchaser for unique applications.
The hose, when subjected to a static pressure of 100 PSI,
shall be capable of withstanding a surface temperature of
300°F for a minimum of two minutes without rupture or
damage to the synthetic reinforcement.
Hose Weight and Coil Diameters
The hose shall conform to the following average weights and diameters
The color shall be black.
