DELPHI FITTINGS
Part Number: 4503
Beaded Hose Barb x NPTF Pipe Male 45° Elbow
Product Overview
The Delphi Fittings Part 4503 is a versatile 45° elbow adapter designed to connect a low-pressure hose to a female NPTF (National Pipe Taper Fuel / Dryseal) port at a 45-degree angle. 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 4503 adapter is a durable and cost-effective choice for a wide range of low-pressure fluid transfer applications requiring an angled connection.
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) |
| Angle | 45 Degrees |
| Body Style | 45° Elbow 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. |

Applications
The Part 4503 Beaded Hose Barb elbow is ideal for a wide range of low-pressure applications where a 45-degree turn is needed to optimize routing, including:
- Connecting low-pressure air, water, coolant, or fuel lines to NPTF or NPT ports at a 45-degree angle.
- Automotive systems such as engine coolant lines, vacuum hoses, and low-pressure fuel lines (with compatible hose material) where space constraints require a smooth angled connection.
- Industrial applications including pneumatic lines, general fluid transfer, and drainage lines that need to navigate around obstructions.
- General purpose plumbing and air compressor setups where a secure, clamped hose connection is needed at a 45-degree angle.
Installation & Usage Guidelines
- If mating with a standard NPT port, apply a compatible thread sealant to the male NPTF threads. Thread the fitting into the port and tighten with a wrench on the hex body until the desired 45-degree orientation and a secure seal are achieved.
Why Choose Delphi Fittings Part 4503?
- Secure Angled Hose Connection: The 45-degree elbow combined with a beaded barb provides a secure, directional connection for low-pressure hoses, allowing for smoother routing than a 90-degree elbow.
- Versatile Adaptation: Easily adapts common low-pressure hoses to standard NPTF threaded ports at an angle.
