Laminova A43-180A Oil Cooler — 180mm Core, Thread-On AN Water Fittings

The Laminova A43-180 is a mid-size 180mm-core oil-to-water heat exchanger built around Laminova’s laminar-flow extruded aluminum core — the same cylindrical, solder-free construction used across the full Laminova line. Coolant and oil are separated by an almost infinite series of interlocking laminar fins (0.2mm thick, 0.3mm oil flow gap), which keeps oil flow laminar instead of turbulent for high heat transfer with very low pressure drop. In application, a 180mm Laminova core performs similarly to a typical 16–19 row air-to-air cooler, in a fraction of the space and without consuming front-end air flow.

This A43-180A configuration ships assembled with thread-on AN water fittings and your choice of AN oil connection — select your water fitting size and oil fitting size above. Standard water connections are -16AN, -20AN, or -24AN thread-on; standard oil connections are -6AN, -8AN, -10AN, or -12AN thread-on. Need a different combination, a push-on water fitting, or a banjo oil connection?

• 180mm core length, ~10.20" overall body length, ~2.7" housing diameter
• Extruded aluminum construction (EN-AW-1050A, 99.5% aluminum)
• O-ring sealed, solder-free modular housing — disassembles for cleaning/service
• Robust, vibration- and pulsation-resistant construction well suited to racing, off-road, and industrial duty
• Sold as a complete assembled unit: core, housing, seals/gaskets, hardware, and your selected fittings

Ideal for engine oil, transmission, or power steering cooling in road racing and other motorsport applications, and equally well suited to robotics, drone, experimental/light aircraft, marine, and light industrial fluid-cooling systems where a high-efficiency cooler is needed.
