Trans Cooler Fitting Brass 1/4in Male npt-5/1

The Trans Cooler Fitting Brass 1/4in Male NPT-5/16 from BE-COOL RADIATORS is an essential adapter for transmission fluid cooling systems in modern performance and heavy-duty vehicles. This brass compression fitting bridges transmission cooler lines to radiator mounting points, managing heat dissipation in automatics that generate excessive fluid temperatures under load, towing, or sustained acceleration. Whether you're upgrading a stock cooling setup or fabricating a custom transmission cooling circuit, this male NPT fitting provides the secure, leak-free connection point your system demands.

Machined from durable brass, this fitting resists corrosion and thermal cycling far better than zinc-plated steel alternatives, critical when fluid temperatures routinely exceed 180°F. The 1/4-inch male NPT (National Pipe Thread) connection ensures compatibility with standard transmission cooler line diameters and radiator tank ports, while the 5/16-inch outlet allows proper flow rates without restricting cooling efficiency. Brass naturally maintains thread integrity under repeated assembly and disassembly, a real-world advantage during system troubleshooting or cooler maintenance without risk of stripped ports that plague lesser materials.

Mechanics and restoration shops installing auxiliary transmission coolers, upgrading factory systems on lifted trucks, or converting carbureted classics to modern automatics will find this fitting indispensable. It's equally suited for replacing corroded fittings in aging cooling circuits or integrating aftermarket coolers into custom engine bays where stock mounting won't accommodate modern performance requirements. Installation requires only standard wrenches and Teflon tape on male threads; the compact 1.5-inch length minimizes installation footprint in tight engine compartments while the lightweight design adds negligible weight to your cooling system assembly.
