What Is It?

This is a double male hose adapter used to connect two female-threaded hose or fittings. It allows seamless conversion between different hose sizes while maintaining thread compatibility.

How Is It Used?

Thread each end of the adapter into female hose couplings to join hose or equipment. Commonly used in fire departments, industrial facilities, and emergency response setups to adapt hose configurations quickly.

Who Uses It?

Firefighters, industrial maintenance teams, municipal water crews, and emergency responders rely on these adapters for fast and secure hose connections in high-pressure environments.

Maintenance Information

Inspect periodically for wear, thread damage, or corrosion. Clean with water and mild detergent. Avoid cross-threading during installation. Store in a dry environment to preserve the hardcoat anodized finish.

What Is It Used With?

Compatible with fire hose, hydrants, water pumps, and industrial hose systems using NH/NST threads. Can be used with aluminum or brass fittings.

Material

Hard-coated extruded 6061-T6 aircraft-grade aluminum alloy

Installation Instructions

Identify Thread Type and Size

• Before installation, confirm the thread type (NH/NST, NPSH/SIPT, or NPT) and size of both hose ends. The AA+136 adapter supports National Standard Thread (NST/NH) by default. NPT is considered a special thread and must be specified when ordering.

Inspect the Adapter

• Check the adapter for any visible damage, debris, or wear. Ensure the threads are clean and free of corrosion or burrs.

Align and Thread

• Align the male ends of the adapter with the female hose couplings.
• Carefully thread the adapter into each hose end by hand. Avoid cross-threading by ensuring proper alignment before tightening.

Tighten Securely

• Use the rocker lugs to hand-tighten the adapter. These lugs provide grip and leverage for a secure fit. Do not use tools that may damage the lugs or threads unless absolutely necessary.

Pressure Test (Optional but Recommended)

• If used in high-pressure applications (e.g., firefighting), perform a pressure test to ensure leak-free performance. The adapter is made from hard-coated 6061-T6 aluminum and is designed for durability under pressure.

Final Inspection

• Once installed, inspect the connection for gaps, leaks, or misalignment. Ensure the adapter is seated properly and securely.

Troubleshooting Tips

1. Cross-Threading Issues

• Symptom: Difficulty threading or misalignment.
• Solution: Ensure both hose ends and adapter threads are clean and properly aligned before installation. Always hand-thread first to avoid cross-threading. If resistance is felt early, back off and realign.

2. Leaks at Connection Points

• Symptom: Water leakage during use.
• Solution: Check for worn or damaged threads. Inspect female hose ends for cracks or deformities. Ensure the adapter is fully seated and tightened using the rocker lugs. If leaks persist, consider using thread sealant or replacing damaged components.

3. Adapter Won’t Fit

• Symptom: Adapter does not thread into hose or equipment.
• Solution: Verify thread type and size. The AA+136 supports NH/NST threads by default. If using NPT or NPSH threads, ensure the correct version was ordered. NPT is considered a special thread and must be specified when ordering1.

4. Rocker Lug Damage

• Symptom: Difficulty gripping or tightening the adapter.
• Solution: Inspect rocker lugs for wear or deformation. Avoid using tools that may damage the lugs. Replace the adapter if lugs are compromised.

5. Corrosion or Surface Wear

• Symptom: Visible wear or corrosion on the adapter.
• Solution: The adapter is made from hard-coated 6061-T6 aluminum, which resists corrosion. If corrosion appears, clean with mild detergent and water. Avoid abrasive cleaners. Store in a dry environment to preserve the finish.

6. Adapter Stuck in Hose

• Symptom: Adapter cannot be removed easily.
• Solution: Apply penetrating lubricant to the threads and gently work the adapter loose using hand pressure. Avoid excessive force or tools that may damage the threads.
