Straight Hose Barb Fitti ng 1/4 NPT F x 3/8 Barb

The DERALE Straight Hose Barb Fitting 1/4 NPT F x 3/8 Barb (Part No. 98104) is a precision brass adapter engineered for fluid transfer systems where reliable, leak-free connections are essential. This straight-entry design transitions from 1/4-inch NPT female threads to 3/8-inch hose barb configuration, making it ideal for coolant lines, fuel systems, and hydraulic applications where space and seal integrity are critical considerations.

Constructed from natural brass, this adapter provides superior corrosion resistance and dimensional stability across temperature cycles common in automotive and marine cooling systems. The 1/4-inch NPT female inlet accepts standard threaded connections with PTFE tape or pipe dope sealant, while the 3/8-inch barb outlet accommodates fuel and coolant hose securely without additional clamps in low-pressure applications. The straight profile eliminates flow turbulence and allows direct mounting in confined engine compartments and chassis locations where angled fittings would create packaging conflicts.

This adapter is widely used in custom cooling system builds, overflow tank plumbing, heater circuit modifications, and auxiliary fluid distribution on street rods, off-road vehicles, and marine engines. Technicians and builders select DERALE fittings for applications requiring precise sizing and repeatable thread-to-barb transitions without dead-end cavities that trap sediment or promote corrosion. At 0.08 lbs, the compact profile suits tight installations where weight and space savings matter.
