Flow manufacturers a wide range of Oil windows for gearboxes, pumps and hydraulic applications.

The oil windows are available in selection of materials such as Aluminium, Steel, Brass and plastic. With various thread options from 1/8" to 2" BSP/ NPT and Metric threads.

Aluminium Oil Window/ Bulls eye:

Made of Aluminium and Glass, these are suitable for low presure applications.

Benjo Bolt Type oil level indicators:

These are specially designed to suit heavy duty applications. The banjo bolt design provides ease of installation. The length can be made to order giving flexibility to maximise visualisaton.

Seals:
Nitrile Rubber
The seal is bedded into a undercut groove which prevents it from dropping out and at the same time stops it from being extruded when tightening the cap. The seal can therefore be kept fairly soft which will improve sealing on uneven surfaces.


Custom Made:
We can manufacture Oil windows to drawings / samples to suit individual applications.
