2.7 High Pressure Hoses,
Connections & Fittings
The ultra-high pressure hoses used in the SK2000
water blasting system are tough but not invin-
cible. They require proper care and handling to
achieve maximum life expectancy. Only use high
pressure hoses with an operating pressure rating
of 40,000 psi (2758 Bar) and a listed burst rating
of 60,000 psi (4,137 Bar). The primary ultra-high
pressure hose transfers the water from the UHP
pump to the blasting head. The hose is secured to
the blasting head thru-shaft with the swivel nut.
A swivel seal and brass backup ring are installed
in the fitting at the swivel nut connection creat -
ing a Ultra-High Pressure seal while allowing the
thru-shaft to rotate freely. The swivel seal has a
life expectancy of approximately 12 to 16 hours
depending on the quality of water.
All high pressure hoses, fittings and connections
have weep holes. Water leaking from a weep
hole while the system is pressurized indicates
that there is a worn or defective seal, loose con-
nection or a damaged part. It is critical that the
operator and/or maintenance personnel inspect
the ultra-high pressure hoses, hose connections
and fittings prior to the start of each shift, periodi -
cally throughout the shift and anytime there is a
loss in pressure. Any hose, fitting or component
that shows signs of deterioration, wear or leakage
should be replaced immediately and before oper-
ating any high pressure water blasting equipment.
A more thorough inspection of all high pressure
pumps and components should be conducted at
each routine service interval.
