OCP Oil Prime 12000-46 — Rotary Screw Compressor Oil | ISO VG 46, 12,000 h

In stock

OCP Oil Prime 12000-46 (formerly OCP Oil Ultra 12000-46) is our top-of-the-line PAG (polyalkylene glycol) lubricant for oil-injected rotary screw air compressors, engineered for extended service intervals of up to 12,000 operating hours under normal conditions.

Exceptional oxidation and thermal stability keep coolers and airends clean over the full drain interval, with a viscosity index of 166 and a pour point of −54 °C for reliable operation across demanding conditions.

A direct, transparently priced alternative to PAG-based OEM lubricants such as Ingersoll Rand SSR Ultra Coolant and Shell Corena S5 R.

Key Performance Benefits

Next-generation oil-soluble PAG technology engineered for extreme service life and clean compressor operation

Up to 12,000-Hour Drain Interval

Designed for extended drain intervals of up to 12,000 operating hours, significantly reducing oil change frequency, maintenance costs, and compressor downtime under demanding industrial conditions.

Varnish-Free & Self-Cleaning Operation

Advanced oil-soluble PAG chemistry prevents varnish formation and actively dissolves existing varnish, keeping screws, coolers, and internals clean even at high temperatures.

Seamless Changeover Compatibility

Fully miscible with mineral oil, PAO, and ester-based lubricants, allowing easy upgrades to PAG technology without flushing or cleaning, even if changeover procedures are not perfect.

Outstanding Lubricity & Wear Protection

Exceptional lubricating performance ensures long compressor lifetime, reduced wear, and stable operation across the entire service interval.

Superior Thermal & Oxidation Stability

High thermal conductivity and excellent thermo-oxidative resistance result in cooler running compressors, stable viscosity, and reliable performance in both low and high temperature environments.

Hydrolytically Stable & Environment-Aware

100% hydrolytically stable, extremely low oil carry-over, and formulated with readily biodegradable base stocks, making it ideal for harsh environments and poor air quality conditions.

Why Choose OCP Oil Prime 12000-46?

A next-generation PAG solution that outperforms traditional PAO oils in service life, cleanliness, and reliability — without the complexity of conventional PAG changeovers

What warranty and performance guarantee do you offer?

OCP Oil Prime 12000-46 is backed by our performance commitment: we guarantee the advertised 12,000-hour drain interval when the product is used in rotary screw air compressors under normal operating conditions, according to the manufacturer specifications. Performance is validated through rigorous testing against international standards, including ASTM D4052 (density), ASTM D445 (viscosity), ASTM D892 (foam tendency 0/0; 0/0; 0/0) and ASTM D130 & D665 (corrosion protection, 1a rating and pass).

Our varnish-free operation guarantee: if varnish deposits form under normal operating conditions - including moisture exposure and temperatures within specification - we will work with you to resolve the issue.
