This method of cleaning is not suitable for use with pressure gauges which are fitted
with coiled bourdon tubes, nor any gauges which are to be used on oxygen, as
complete removal of oil is not assured. Please contact DH-Budenberg/WIKA.
Equipment
This consists of a syringe and a special needle with the point bent through 90°.
Instructions
1. Fill syringe with solvent (suitable cold degreasing liquid).
2. With gauge connection pointing upwards put needle into connection and insert by
feel the point into the hole leading to the tube.
3. Inject the solvent. Ideally the tube should be half full.
4. Shake gauge in various attitudes to agitate solvent.
5. Suck solvent back into syringe, holding gauge at an angle.
6. Check that solvent removed is clean. To be sure that all oil has been removed,
repeat cleaning process until solvent removed from gauge is as clean as that put in.
