EN 541 Plastic Fluid Level Sight Glasses, with or without Reflector
ELESA Original design
code: HFTX.

Product description

Information

EN 541 Elesa® original design technopolymer crystal-clear plastic fluid level 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.
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.
