Special transparent polyamide technopolymer plastic (PA 6-T)
Seal: NBR rubber (Perbunan)
Elesa® original design technopolymer plastic dome-shaped fluid level
Mainly used as oil circulation indicators.
Practically indestructible; even if high torque is applied there is no danger of breakage.
Resistant to aging, not alcohol resistant.
Because of the high strength of the material (considerably stronger than, for example, Plexiglass), these site glasses can be produced with much thinner walls, resulting in clearer visibility. The ratio between bore diameter and the viewing window is much improved.
A moderate torque (not exceeding 3-12 Nm) is recommended when tightening
oil sight glass so as to guarantee optimal tightness without
any elastic deformation. Full details regarding torque available upon request.

Note: When mounting oil level sight glasses on walls
of less than 4mm thickness, use nut GN
