BPV21/BPV31 Bullet Piercing Valves are compact bullet piercing valves made for quick access to refrigeration lines when you need it most. They’re handy for travellers running portable fridges, small refrigeration setups, and “just-in-case” kits where fast line access matters.

They clamp on securely, don’t need an adapter valve, and come with a hex key so you can install with simple, controlled torque.

Best for: HVAC techs, service and maintenance teams, and practical campers/4WD tourers who want compact line access gear for portable fridges and small systems.

Compatible with: Small refrigeration systems and portable fridge setups where a clamp-on access valve is suitable. If you’re working on a different line material or tube size, check the model specs and your line OD before install.

Using Your Bullet Piercing Valve: Step-by-Step

1. Isolate power to the fridge/system and let pressures stabilise.
2. Confirm you’ve got the right model (BPV21 or BPV31) for your line size.
3. Choose a suitable spot on a clean, straight section of line (avoid damaged or corroded areas).
4. Fit the valve over the line and align it as per the valve body design.
5. Tighten evenly with the included hex key until firmly clamped.
6. Follow the valve’s piercing procedure and connect your service gear as required.
7. Leak check after install, refit caps, and re-check after the system has run.

Limitations & Safety Notes

• Refrigerant handling should be done by a licensed technician where required (do not vent refrigerant).
• Only install on suitable line material and the correct tube size for the model.
• These are for service access/diagnostics—if you need a permanent solution, install a proper service port/valve.
• Do not work on live electrical components—always isolate and test first.
• Always leak test after fitting and keep caps fitted to reduce the chance of slow leaks.
• If you’re unsure, stop and confirm the correct setup before proceeding.

Bullet Piercing Valves FAQs

What’s the difference between BPV21 and BPV31?

They suit different tube sizes or setups. Check your line outside diameter (OD) and match it to the correct model before ordering.

Are bullet piercing valves a permanent fix?

They’re often used for access and diagnostics. For long-term reliability, a proper brazed-in service port/valve is usually the better option.

Do I need an adapter valve?

No—these models are designed so no adapter valve is required, which helps speed up installs in the field.

How much pressure can they handle?

These valves are rated up to 500 PSI. Always confirm suitability for your specific application and refrigerant setup.

What should I check before installing?

Confirm tube size (OD), confirm the line material is suitable, choose a clean straight section of line, and plan for a leak test after fitting.

Do they come with tools?

Yes—each valve includes a hex key wrench for quick installation.
