Brass Fluid Level Sight w/ ESG Glass w/ Reflector - 3/8" NPT Thread - J.W. Winco 6PSMA

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 743.1 can be used on pressurized oil tanks. Viton seal: maximum heat resistance: 180° C (356° F). ...

No thread is required for installing the GN 537 fluid level sight glasses.The fluid level sight glass is inserted into the bore d2, tolerance H11. By simply tightening the ring nut using the pin key, the seal is pressed against the contact surface which, at the same time, holds the sight glass in position. For removal, reverse the procedure. Application is limited to non-pressurized or slightly pressurized tanks. Maximum heat resistance: 80° C (175° F).

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 ...

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 European guidelines for explosion protection introduced on 7/1/03 (ATEX) also cover explosion protection in the mechanical sector. Fluid level sight glasses GN 743.6 are suitable for use in an explosion risk environment, and comply with guidelines 94/9/EG. Detailed documentation accompanies this part when ordered. Features: 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. Seal is housed in a groove and therefore cannot be lost. Meanwhile, this ...
