Hoses, Piping and Fittings
All hoses, piping and fittings should be supplied and installed in accordance with the manufacturer’s
instructions and should be suitable for use at the pressures and flows to be experienced by Automist with
the necessary factors of safety.
Fittings
•
1/4” BSP Female thread with swivel nut with 60° cone mating surface
•
Material: mild steel (zinc plated)
•
IMPORTANT!
Do not use stainless steel material for any fitting or hose adapter, unless all other
fittings are stainless steel too.
Hose General
Approved suppliers of hoses:
Hydroscand (several locations in the UK)
When installing flexible high-pressure hose behind plasterboard walls, Plumis recommends the hose is left
free and unconstrained. This is because mounting the hose in a conduit or narrow groove within joists
makes it more susceptible to perforation when subsequent building works are carried out. Flexible high-
pressure hoses must be mounted as close to the ground as possible and within the wall. For cases where
the hose is exposed in the room, conduit sleeves must be used. Where the hose is surface mounted more
than 1.2m from the floor in a protected room, or where the hose passes above/within the ceiling of a
protected room, a suitable thermally insulating sleeve may be required.
•
1/4” or 5/16” nominal inner diameter
•
Hose working pressure of at least: 150 bar
•
Minimum burst Pressure: 600 bar
•
60m maximum hose length if both 5/16” and 1/4” hoses are used, made up with a maximum of
20m 1/4” hose and a maximum of 40m 5/16” hose
•
50m maximum hose length if only 5/16” hose is used
•
Any hoses crimped by the installer or on-site must be pressure tested to at least 160 bar and
checked for leaks, before connection to the Automist pump
a)
Hose with 1/4" Inner Diameter

Plumis supplied hose lengths of 4m:
o
Minimum curvature working radius: 40mm
o
Plastic exterior to withstand some abrasion during installation and maintenance works
o
Hose is pressure tested in factory assembly to 2X working pressure (300bar, so no site
testing is necessary)
Hydroscand supplied 1/4” hose with customized length:
