For manifolds with custom length hoses change first hose (inlet) or second hose (outlet) to desired length. Contact your Ralston Instruments dealer or the
factory for pricing on custom length hoses. For accessories, repair kits and hoses see page 17. For a complete list of accessories and parts see product manual or
detailed specification sheet. For a list of the most commonly used gauge and process connections see page 18. For a complete list refer to Ralston Instruments
Pressure Connection catalog. Contact your Ralston Instruments dealer or the factory for information on reference gauges and pressure calibration kits.
