HVAC Control Spin-On Filter
The Baldwin Filters BT338 is a spin-on HVAC control filter built with a by-pass lube design for heavy-duty equipment. It fits Caterpillar, Kobelco, MDI-Yutani excavators and Mitsubishi engines that require an M18 x 1.5mm thread connection.
Integral Gasket and Post Seal
The unit includes a G324-A integral gasket and an integral post seal, removing the need for separate sealing components during installation. This combined sealing arrangement simplifies service intervals and helps maintain a consistent seal under operating pressure.
M18 x 1.5mm Thread Constraint
The M18 x 1.5mm thread size limits fitment to engines and housings machined for that specific pitch and diameter. The 9.8 micron rating defines the filtration threshold, so systems demanding finer particle capture will require a different filter specification.

Questions about this item
How often should the spin-on filter with 9.8 micron rating be replaced on a Caterpillar excavator?
Replace the BT338 spin-on filter at the engine manufacturer's recommended service interval; the 9.8 micron rating and integral post seal maintain protection until that scheduled change.
What pressure limit does the by-pass valve inside the BT338 hit first during extended operation?
The by-pass lube spin-on design opens if flow restriction exceeds the valve's calibrated setting, preventing oil starvation when the 9.8 micron media loads up.
Does the M18 x 1.5mm thread housing run hotter than the engine block during all-day use?
The aluminium canister reaches normal oil temperature quickly; the integral G324-A gasket and post seal handle continuous heat cycles without leakage.
