Part Number: 4404

Beaded Hose Barb x NPTF Pipe Male Adapter

Product Overview

The Delphi Fittings Part 4404 is a versatile straight adapter designed to connect a low-pressure hose to a female NPTF (National Pipe Taper Fuel / Dryseal) port. This fitting features a beaded hose barb on one end, engineered to provide a secure grip for a hose secured with an external clamp. The raised bead offers a positive stop and an excellent shoulder for the clamp to tighten against, preventing hose slippage. The other end features a male NPTF thread for a reliable, tapered seal into standard pipe-threaded ports. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the 4404 adapter is a durable and cost-effective choice for a wide range of low-pressure fluid transfer applications.

Key Features & Specifications

Material	High-Grade Carbon Steel
End 1 Configuration	Beaded Hose Barb
End 2 Configuration	Male NPTF Pipe (Dryseal) (conforming to ANSI B1.20.3 / SAE J476)
Body Style	Straight Adapter with hex features for wrench tightening.
Sealing Mechanism	Hose Barb End: The hose is pushed over the barbs, and a hose clamp is tightened behind the bead for secure retention. NPTF Male End: Forms a Dryseal (metal-to-metal) with a mating female NPTF port. If mating with a standard NPT female port, thread sealant is recommended for optimal sealing.
Corrosion Protection	Standard Zinc Plating for enhanced durability.

Crucial Application Note: This fitting is intended for **low-pressure applications only**. The connection's pressure rating is limited by the hose and clamp type and is not suitable for medium or high-pressure hydraulic systems. Always confirm the pressure rating of all components in your assembly.

Applications

The Part 4404 Beaded Hose Barb adapter is ideal for a wide range of low-pressure applications, including:

Connecting low-pressure air, water, coolant, or fuel lines to NPTF or NPT ports.
Automotive systems such as engine coolant lines, vacuum hoses, and low-pressure fuel lines (with compatible hose material).
Industrial applications including pneumatic lines, general fluid transfer, and drainage lines.
General purpose plumbing and air compressor setups where a secure, clamped hose connection is needed.

Installation & Usage Guidelines

If mating with a standard NPT port, apply a compatible thread sealant to the male NPTF threads. Tighten the fitting into the female port using a wrench on the hex body.

Why Choose Delphi Fittings Part 4404?

Secure Hose Connection: The prominent bead provides a strong shoulder for the hose clamp to tighten against, offering enhanced retention compared to a standard barb and preventing hose slippage in low-pressure applications.
Versatile Adaptation: Easily adapts common low-pressure hoses to standard NPTF threaded ports found on a wide range of equipment and components.
