DELPHI FITTINGS
Part Number: 4501
Beaded Hose Barb x NPTF Pipe Male 90° Elbow
Product Overview
The Delphi Fittings Part 4501 is a versatile 90° elbow adapter designed to connect a low-pressure hose to a female NPTF (National Pipe Taper Fuel / Dryseal) port at a right 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 4501 adapter is a durable and cost-effective choice for a wide range of low-pressure fluid transfer applications requiring a directional change.
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 | 90 Degrees |
| Body Style | 90° 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 4501 Beaded Hose Barb elbow is ideal for a wide range of low-pressure applications where a 90-degree turn is needed, including:
- Connecting low-pressure air, water, coolant, or fuel lines to NPTF or NPT ports at a right angle to optimize routing.
- Automotive systems such as engine coolant lines, vacuum hoses, and low-pressure fuel lines (with compatible hose material) where space constraints require an elbow.
- Industrial applications including pneumatic lines, general fluid transfer, and drainage lines that need to navigate corners.
- General purpose plumbing and air compressor setups where a secure, clamped hose connection is needed at an angle.
Installation & Usage Guidelines
- Ensure the hose inner diameter (ID) matches the specified barb size for a proper fit.
- Cut the hose end cleanly and squarely using a sharp hose cutter.
- Slide a suitable hose clamp (e.g., worm gear clamp) over the end of the hose before fitting it onto the barb.
- Push the hose completely onto the barb until the hose end makes contact with the back of the bead.
- Position the hose clamp on the hose in the area between the bead and the main body of the fitting. Do not place the clamp directly on top of the bead.
- Tighten the clamp securely according to the clamp manufacturer's specifications to ensure a firm grip without damaging the hose.
- 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 orientation and a secure seal are achieved.
