1/2 Male x 3/8 Female Reducer Bushing

The DERALE 1/2 Male x 3/8 Female Reducer Bushing (Part No. 98452) is a straight-thread adapter fitting that bridges NPT connections of different sizes in fluid transfer systems. Constructed from brass, this reducer bushing provides reliable flow control where a 1/2-inch NPT male port must mate with a 3/8-inch NPT female connection, making it essential for cooling systems, hydraulic lines, and aftermarket fluid management installations.

Brass construction offers superior corrosion resistance compared to steel adapters, particularly in environments exposed to coolant, brake fluid, or moisture. The straight-thread design (as opposed to tapered NPT threads) ensures consistent fit when used with matching port configurations. This 1/2 x 3/8 reducer bushing maintains pressure integrity while allowing technicians to downsize from larger plumbing without requiring complete system redesign. The compact dimensions (2.75 x 1.35 inches) and minimal weight (0.08 lbs) make it suitable for tight engine bay installations and custom fabrication work.

This adapter is used in automotive cooling upgrades, transmission cooler installations, oil cooler retrofits, and general hydraulic system modifications where port size compatibility is needed. DERALE reducer bushings are commonly selected by shops performing fluid line consolidation or system repairs that require stepping down from standard 1/2-inch fittings to 3/8-inch components. Each bushing ships as a single unit, allowing buyers to purchase exactly the quantity needed without excess inventory.

The natural brass finish resists oxidation and provides visual confirmation of material quality during installation. Proper thread sealant application (PTFE tape or pipe dope) is recommended to ensure leak-free operation under system pressure.
