This product is for use to test the braking oil duct for possible damage,leak or block;to test braking oil pump for possible damage,leak or block to prevent brake failure.It is applicable to various type and design of vehicles.
Measuring range:0-20 Mpa(0-3000psi)
Operational principle and structure
YZJ-70 Type Oil Pressure Gauge consists of pressure gauge, hose of connector and two connectors. The pressure gauge consists of connector, Bourdon tube, metric (British measurement) double scale dial plate and indicator. When it is used, engine oil flows into the Bourdon tube through hose and connector, which brings displacement of free end of the Bourdon tube, and as a result, the indicating needle rotates by means of gear drive to indicate pressure value on the dial plate.
This pressure gauge is provided with Z3/8〞NPTF thread, Z1/4〞NPTF thread, two connectors and hose coupler(1000mm long), thus it can be flexibly used to test oil pressure of engines different in positions and sizes.
Product Specification / Models
First take down the low oil pressure switch and install oil pressure gauge by means of proper adapter that suits the engine, then start the engine and read out the pressure value indicated on the pressure gauge; after that, stop the engine, take down the oil pressure gauge, and finally install the low oil pressure switch.
