polyamide technopolymer plastic (PA 6-T)
Reflector: Star-shaped anodized
aluminum with central level sight dot
Packing ring: NBR synthetic rubber (Perbunan)
Elesa® original design technopolymer plastic fluid level sight glasses.
EN 541 sight glasses are practically indestructible. Even at high torque there is no danger of any breakage.
Can also be used in pressurized tanks. The maximum allowable pressure is dependent on the tank size operating conditions (i.e. temperature). Test results are available upon request.
Resistant to solvents, oils, grease and other chemical agents, but not suitable for alcohol.
The particular shape of the lenticular window increases and
improves visibility even from side positions.
A moderate torque (see table) is recommended when tightening
oil level indicator so as to guarantee optimal tightness without
any elastic deformation.
For mounting on walls of less than 4 mm thickness please use GN 543.1 Thin Hex Nuts.
BSPP thread sizes available upon request.
Maximum continuous working temperature at 3 Bar pressure:
