Product Description
GN743 Oil Level Sight Glass, Aluminium & Float Glass, Blank
Oil level sight glasses GN 743 have scratch proof, highly stable glass, with optional contrast screen. The sealing is achieved with an O-ring on the periphery and not on the face edge of the glass. Leak tightness is therefore not affected by axial pressures.
The outside diameter of these oil level sight glasses with recessed hexagon is designed to match mounting holes for tube connections according to DIN 3852.
The seal is housed in a groove and it can therefore not be lost. In addition, this groove prevents the seal from being extruded when the sight glass is tightened. The location of this seal allows also the use of a softer Elastomer which guarantees better and easier sealing.
We can offer this product with SW black powder coat finish. Price is available on request via our sales team +44 (0)1732 763377. Minimum quantity 500pcs.
Oil level sight glasses GN743 can be used on pressurised oil tanks. Tests regarding maximum pressure are available on request.
