Baldwin BT8903 Hydraulic Spin-On Filter
This Baldwin BT8903 is a new hydraulic spin-on filter designed for industrial fluid systems. It threads directly onto a 1-12 port and includes an integral G381-A gasket for a reliable seal. Maintenance crews and equipment operators use it to keep hydraulic circuits clean.
18-micron rating with 8 25/32-inch height
The element captures particles down to 18 microns, providing solid contamination control for typical hydraulic reservoirs. Flow capacity suits standard industrial circuits, though very high-volume loops may need a larger housing or parallel filters.
Compact 3 11/16-inch diameter for tight mounts
The spin-on canister measures 3 11/16 inches across, allowing installation where space is limited. Normal operation adds minimal pressure drop and runs quietly because fluid passes through the media without moving parts. No external power is required.

Questions about this item
Will the 1-12 thread on this BT8903 filter match the port on my older hydraulic power unit?
The filter uses a 1-12 thread size; verify that your power unit's mounting port uses the same 1-12 specification before installing.
How can I confirm the 18 micron rating is actually filtering my hydraulic fluid after installation?
Monitor system pressure drop across the filter; a stable differential within the manufacturer's normal range indicates the 18 micron media is flowing and capturing contaminants as designed.
Does the BT8903 come with the G381-A integral gasket installed, or do I need to buy a separate seal kit?
The G381-A integral gasket is included with the filter; no separate seal kit is required for installation.
