Aluminum Fluid Level Sight Glass w/ Prismatic Reflector - M27 x 1.5 Thread - J.W. Winco R52

Protective glass objective cover for EMZ zoom stereo bodies (Except EMZ-12 Series).

Genuine glass of high stability and scratch proof. Sealing 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 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 softer elastomer which guarantees better and easier sealing. Fluid level sight glasses GN 743 can be used on pressurized oil tanks. NBR seal: maximum heat resistance: 100° C (212° F). When ...

Genuine natural glass of high stability and scratch proof. Sealing 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. Outside diameter is chosen to match mounting holes for tube fittings according to DIN 3865. Seal is housed in a groove and therefore cannot be lost. Meanwhile, this groove prevents the seal from being extruded when the sight glass is tightened. The location of this seal also allows the use of a softer Elastomer, which guarantees better and easier sealing. Fluid level sight glasses GN 743.2 can ...

The conical thread of GN 743.7 fluid level sight glasses makes a metallic seal possible. When the male thread is tightened, it wedges itself within the appropriate female thread. At the reference level "a," the male thread has the same thread diameter as the female thread, so that it can be fastened in by hand. The secure tightening by means of a tool increases the length of engagement and seals the screw connection. Additionally a sealant (fibrous or teflon band) is usually used. The thread is "roughened," so that the sealant does not shift during fastening. Fluid level sight glasses GN ...
