2.6 High Pressure Hoses,
Connections & Fittings
The ultra-high pressure hoses used in the SH8000
Waterblasting system are tough but not invincible.
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 high pressure “two way” Y connector at the
front of the chassis. The connector splits the high
pressure water supply to a high pressure hose
for each blasting head. The hoses are 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
