OIL CIRCULATION SIGHTS

FEATURES

Resistant to solvents, oils with additives, greases, acids and alkalis. Avoid

contact with alcohol or detergents containing alcohol.

An adequate tightening torque is recommended when screwing the

oil circulation sight, so as to guarantee optimal tightness without any

deformation of the packing ring. Suggested tightening torque is the result

of laboratory tests at ambient temperature (23°C) with sight, packing ring

and reservoir walls perfectly cleaned.

SPECIFICATIONS

Working temperature range -30°C to +100°C

Materials

Transparent polyamide based (PA-T)

technopolymer. NBR rubber flat packing ring

Oil level check

Delimited by a small red coloured externally

tampoprinted circle

OIL SIGHT GLASS

FEATURES

Oil level indicators with prismatic transparent window for high

temperatures. The window consists of a continuous series of prisms

which provide a instant, clear reading, of the level of the oil contained in

the reservoir.

The tightening torque indicated in the table guarantees an optimal

tightness, keeping the packing ring in the correct position.

An adequate tightening torque is recommended when screwing the

oil level indicator, so as to guarantee optimal tightness without any

deformation of the packing ring.

Suggested tightening torque is the result of laboratory tests at ambient

temperature (23°C) with indicator, packing ring and reservoir walls

perfectly cleaned.
