CUSTOMER BENEFITS

Chevron GST 2190 EP delivers value through:

• Long lubricant life because of selected base stocks and additives.
• Extreme pressure characteristics help provide high film strength to protect gears and bearings engaged in heavy-duty service.
• MIL-PRF-17331L and MIL-PRF-17331K(SH) approved — Meets stringent military specifications for Navy vessels and submarines.
• High viscosity index — Minimal viscosity change in broad operating temperature range enhances lubricant film strength.

FEATURES

Chevron GST 2190 EP was developed primarily as a circulating system oil for marine gear turbine sets.

Chevron GST 2190 EP provides mild extreme pressure protection as well as resistance to rust, oxidation, corrosion, and foaming.

Chevron GST 2190 EP has outstanding thermal and oxidation stability which allows it to withstand the high temperatures found in turbine bearing and gear lubrication.

The foam inhibition helps prevent the buildup of foam in the sump tank with possible vent pipe overflow.

Its excellent stability, high viscosity index, and rust and corrosion inhibition help assure high film strength lubrication for gears and bearings, as well as rust and corrosion protection. Together, these qualities promote both long lubricant and equipment life.

It does not contain any silicone additives.

APPLICATIONS

Chevron GST 2190 EP is recommended for use in marine turbine reduction gears, where heavy tooth loading and shock loads are encountered.

The extreme pressure properties enable Chevron GST 2190 EP to meet the requirements of MIL-PRF-17331L and MIL-PRF-17331K(SH).

Do not filter through Fuller’s Earth-type filtration systems since this would deplete the additive package.

Do not use in high pressure systems in the vicinity of flames, sparks and hot surfaces. Use only in well ventilated areas. Keep container closed.
