Product Details

The Perma-Cool 15151 brass adapter fittings provide a reliable connection between 5/16-inch hose barb and 3/8-inch male pipe thread (MPT) components. Constructed from durable brass material, these fittings resist corrosion and provide long-lasting performance in automotive cooling systems, transmission coolers, and oil cooler installations.

Key Features:

  • Brass construction for corrosion resistance and durability
  • 5/16-inch hose barb (HB) connection on one end
  • 3/8-inch male pipe thread (MPT) on opposite end
  • Comes as a 2-piece set for complete installation needs
  • Ideal for transmission coolers, oil coolers, and fluid transfer applications
  • Compatible with standard rubber and reinforced hoses

These adapter fittings are commonly used in automotive performance applications where a hose barb connection needs to interface with standard NPT-threaded ports. The brass material ensures compatibility with a wide range of fluids including transmission fluid, engine oil, and coolant.

Autoplicity simply had the best prices available and everything was in stock to be shipped.

So far so good

Autoplicity leads the way ! Others take a lesson !! Great prices and excellent service !!!

No problems ordering a leak down tester from Autoplicity which had the lowest price and reasonable shipping charges. The item was well packaged and I would buy from them again.
