3. Specifications
Liquids used
A hydraulic mineral oil viscosity 20 ... 37 cSt at 40 °C viscosity grade VG20 to VG37
to ISO 3448 (BS 4231) is used for the CPB3800 base unit. Most users will be able to
obtain locally suitable oil (see below) as used in hydraulic machinery. However, for the
convenience of users we can supply a 500 ml bottle of oil, viscosity grade VG22.
Oils suitable for pressure balances
The following oils are the commercially available oils suitable for use in the pressure
balance.

Other liquids
The pressure balance model CPB3800 is manufactured for use on mineral oil only. If
an end user wishes to use it on another fluid, it is the end user responsibility to ensure
that the fluid is compatible with high tensile brass, stainless steel, mild steel, and nitrile
rubber, which are the materials that will come into contact with the fluid.
Fluids, which attack ABS, should be used with caution. Continual
immersion of the cover in such fluids will cause deterioration. Spillages
should be wiped off immediately.
Wear safety goggles!
Protect eyes from flying particles and liquid splashes.
