Information
This oil sight glass GN 537 does not require a thread.
The oil sight glass is inserted into the bore d2 to H11. By simply tightening the ring nut using the pin key the seal is pressed against the contact surface which, at the same time, will hold the sight glass in position. For removal reverse the procedure.
Their application is limited to non-pressurised or only slightly pressurised tanks.
