Oil level sight glass | SM 1920

made of plastic Material: crystal-clear Polyamid (PA-T)- ageing resistant,- high mechanical strength,- solvent resistant, but not suitable for alcohol,- temperature resistant up to 100° C.rubber seal: Rubber NBR (Perbunan®)contrast screen: aluminium, natural colour, anodized Form A: with contrast screenForm B: without contrast screen Almost unbreakable, no risk of breakage even with high tightening torques. Significantly higher material strength than Plexiglas, for example, therefore the oil sight glasses are relatively thin-walled and have a large inspection opening. Can also be used for pressurized containers. The recommended tightening torque must be observed to prevent deformation of the oil sight glass.For fastening nuts with wall thicknesses of less than 4 mm, see SM 1921. RoHS-compliant: yes
