Aluminum & Glass Inline Coolant Filter with 1 1/4" Inlet / Outlet

• Inline filter traps debris before it reaches your radiator, water pump, or heater core

• Glass body lets you check coolant condition and filter status without disassembly

• Fits any 1 1/4" (32mm) hose setup — universal, not vehicle-specific

• Aluminum end caps with stainless element for a durable, serviceable design

This aluminum and glass inline coolant filter is built to trap debris circulating through the cooling system while giving you a clear view of coolant condition without cutting a hose or draining the system to check. It installs inline using a 1 1/4" (32mm) inlet and outlet, matching common radiator hose sizing on custom and performance cooling setups.

This is a universal-fit filter, not a vehicle-specific part. Fitment depends on matching your existing hose inside diameter to the 1 1/4" (32mm) inlet/outlet — not on make, model, or year. Confirm your hose size before ordering, since inline filters sized for other hose diameters will not seal correctly with this unit.

The stainless steel filter element sits inside an aluminum-and-glass housing, with hose clamps included for installation into a compatible coolant line.

Cooling System Applications
This filter is designed for custom cooling system builds, hot rods, engine swaps, and street performance vehicles running a 1 1/4" (32mm) coolant hose — it's not limited to a specific make or model, so fitment comes down to hose diameter rather than vehicle year.

Installation
Cut into an existing coolant hose section and secure the filter inline using the included clamps, positioning the glass body where it stays visible for routine inspection — commonly in the upper radiator hose. Flush and bleed the cooling system after installation to clear any air pockets introduced during the cut-in.

Is this fitting for the pressure side or return side of my power steering system?
This fitting is designed for the reservoir return (low-pressure) side of the power steering system. It is not intended for high-pressure line connections.

How do I know if my steering box uses O-ring or inverted flare sealing?
Check the port style on your steering box, rack, or pump before ordering. O-ring and inverted-flare connections use different sealing methods and are not interchangeable simply because the thread size appears similar.

What vehicles is this commonly used on?
It's commonly used in GM muscle car, truck, hot rod, and LS-swap power steering systems using the matching port configuration and -6AN hose plumbing. Always verify the actual steering component's port before ordering.
