DESCRIPTION

EVIL ENERGY Metric to Hose Barb Fitting Adapter

Connecting a metric fuel-pump or oil-system port to a standard rubber hose can lead to leaks, damaged threads, or loose hose connections when the thread pitch and barb size are not matched correctly. This EVIL ENERGY metric-to-barb fitting provides a compact transition between compatible metric ports and 5/16, 3/8, 1/2, or 5/8-inch hoses. It is intended for experienced DIY builders and professional installers working on custom fuel, oil-cooler, transmission, and fluid-routing projects.

Select the adapter by matching both the metric thread and the required hose inside diameter.

Choose the Correct Thread and Hose Size

Start by identifying the metric port thread, including both diameter and pitch. Then measure the inside diameter of the hose that will be installed on the barb.

Metric Thread Available Hose Barb Sizes
M10 × 1.0 5/16 in, 3/8 in, or 1/2 in
M12 × 1.5 1/2 in
M14 × 1.5 1/2 in or 5/8 in
M18 × 1.5 3/8 in

Do not select the fitting by the outside diameter of the hose alone. The barb must match the hose inside diameter, and the hose must be compatible with the fluid, temperature, and pressure of the intended system.

Confirm the thread diameter, thread pitch, and hose barb size before ordering.

Secure Metric-Port and Hose-Barb Connections

The CNC-machined 6061-T6 aluminum body provides a precise threaded connection for compatible metric ports. The included aluminum sealing washer or spacer is positioned at the metric side according to the port design.

  • Inspect the metric port and sealing surface before installation.
  • Start the fitting by hand to reduce the risk of cross-threading.
  • Do not force a different metric pitch into the port.
  • Push the hose fully over the barb.
  • Use a correctly sized clamp on the hose side.
  • Keep the clamp behind the raised barb section.
  • Pressure-test the system and inspect the connection for leakage.

Avoid overtightening the aluminum fitting. Excessive torque may damage the fitting, sealing washer, port threads, or the component housing.

Use the supplied sealing component on the metric side and a suitable clamp on the hose side.

Compatible Custom Plumbing Applications

The adapter can be used where a compatible metric-port component must connect to flexible hose. Typical applications include:

  • External fuel-pump inlet or outlet connections
  • Fuel-pressure regulator plumbing
  • Oil-cooler inlet and outlet connections
  • Transmission-fluid routing
  • Oil-return or oil-drain lines
  • Custom automotive fluid systems

This is not a vehicle-specific direct-fit fitting. Compatibility depends on the exact component port, thread pitch, sealing surface, hose size, fluid type, pressure, temperature, and available installation clearance.

Metric to hose barb adapter applications for fuel pump regulator oil cooler and transmission lines
Verify the port, hose, fluid, and installation environment for the specific application.

Check Before Ordering

  • Confirm the metric thread diameter and pitch.
  • Confirm the hose inside diameter.
  • Check the port depth and sealing surface.
  • Verify hose and clamp compatibility.
  • Confirm fluid, pressure, and temperature requirements.
  • Check clearance for installation and future service.

This adapter is a practical choice when the metric port, hose size, and sealing method are known. Choose a different fitting when the port uses a tapered pipe thread, AN flare, ORB connection, or another sealing standard.

FAQS

Q: How do I choose the correct metric-to-hose-barb fitting?
A: Confirm both sides of the connection before ordering. Match the metric port diameter and thread pitch, then select the barb size according to the hose inside diameter.

Q: What metric thread sizes are available?
A: Available options include M10 × 1.0, M12 × 1.5, M14 × 1.5, and M18 × 1.5. The available hose-barb size depends on the selected metric thread.

Q: What hose sizes are available for this fitting?
A: Available barb sizes include 5/16 inch, 3/8 inch, 1/2 inch, and 5/8 inch. Select the barb according to the hose inside diameter, not the hose outside diameter.

Q: Will this fitting work with any M10, M12, M14, or M18 port?
A: No. The thread diameter and pitch must both match. For example, an M10 × 1.0 fitting should not be installed in an M10 port with a different thread pitch.

Q: Is this fitting compatible with NPT or AN ports?
A: No. This product uses a male metric straight thread. NPT tapered threads, AN flare fittings, and ORB connections use different thread and sealing standards.

Q: How does the metric side of the fitting seal?
A: The selected fitting includes an aluminum sealing washer or spacer for the metric connection. Confirm that the component has a compatible flat sealing surface before installation.

Q: Should thread sealant or PTFE tape be applied to the metric thread?
A: Do not automatically apply thread tape to a straight metric connection that seals with a washer. Follow the equipment manufacturer’s sealing instructions for the specific port.

Q: Is a hose clamp required on the barb side?
A: Yes. Push the compatible hose fully over the barb and secure it with a correctly sized clamp rated for the hose, fluid, pressure, and temperature of the system.

Q: Where should the hose clamp be positioned?
A: Position the clamp behind the raised barb section where it can compress the hose evenly. Do not place the clamp on the hose edge or directly over the end of the fitting.

Q: Can this adapter be used on a fuel pump inlet or outlet?
A: Yes, when the fuel-pump port uses the matching metric thread and the hose inside diameter matches the selected barb. Also confirm the pump flow direction, port depth, fuel compatibility, and available clearance.

Q: Can this fitting be used with a fuel pressure regulator?
A: It may be used with a regulator that has a matching metric port and a compatible sealing surface. Do not install it in an NPT, ORB, or AN port.

Q: Can the fitting be used for oil cooler or transmission lines?
A: Yes, when the thread, hose size, fluid compatibility, pressure, temperature, and sealing method match the intended oil or transmission-fluid system.

Q: What material is the fitting made from?
A: The fitting is CNC-machined from 6061-T6 aluminum and has a black anodized finish.

Q: How tight should the aluminum fitting be installed?
A: Use the torque specification provided by the pump, regulator, cooler, or other component manufacturer. A universal torque value is not provided. Overtightening may damage the aluminum fitting, sealing washer, or component threads.

Q: What can cause the connection to leak?
A: Common causes include the wrong thread pitch, damaged threads, a scratched sealing surface, a missing or damaged washer, an incorrect hose size, a loose clamp, or excessive system pressure.

Q: What should I check after installation?
A: Pressure-test or operate the system according to the equipment manufacturer’s procedure. Inspect the metric connection and hose-barb side for leakage, hose movement, clamp loosening, and contact with hot or moving components.

Q: What is included in the package?
A: The package includes one selected metric-to-hose-barb fitting and one aluminum sealing washer or spacer. Hose, hose clamp, pump, regulator, and additional installation hardware are not included.
