Aluminum Fluid Level Sight w/ ESG Glass w/ Reflector - M20 x 1.5 Thread - J.W. Winco R23/A 743.1-14-M20X1.5-A

Ul style"margin-top0px; padding-top 5px; padding-bottom 5px;" 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). When mounting oil level sight glasses on walls of less than 4mm thickness use nut gn 543.1.
