This B&Q Car Aircon Regas Kit is designed for competent DIY users with vehicles using the R1234yf refrigerant system (common in some cars from 2013 onwards). It offers a fast and inexpensive way to recharge your AC, stop minor leaks, and restore peak performance, making warm vehicles ice cold. A key caveat is that it will not repair large mechanical leaks and requires careful identification of your vehicle's AC system type (R1234yf vs. R134a) and the low-side filling port before purchase. The kit includes a hydrocarbon-based refrigerant equivalent, a leak sealer, and a professional manifold hose with a gauge.

Check the label under your vehicle's bonnet or consult your owner's manual. R1234yf is common in many vehicles manufactured from 2013 onwards.
No, this kit is specifically designed for R1234yf systems only. Attempting to use it on an R134a system could cause damage.
This kit includes a leak sealer that can repair minor leaks caused by shrunken seals. It is not designed to fix large mechanical breaches or significant damage to the AC system.
The kit includes a professional hose and gauge. It is designed for competent DIY users. In the UK, it is ozone-friendly and does not require an F Gas license for use.
The refill can contains 226g, equivalent to 456g of R1234yf. The leak sealer can contains 113g, equivalent to 228g of R1234yf.
No, once a can is attached to the hose, it must remain attached until completely empty. It will not self-seal if detached prematurely and may still contain residual pressure.
The gauge measures the pressure within the AC system. Note that the needle does not zero after use and readings are only valid while the system is under pressure. Ensure the engine and AC compressor are running when taking readings.
Ensure the engine and AC compressor were running during the recharge process. Check the gauge readings to confirm the correct pressure level was reached. If the system still doesn't cool, there might be a more significant mechanical issue beyond seal leaks.
The leak sealer is designed for minor leaks from shrunken seals. If the pressure does not hold, you likely have a larger mechanical leak that requires professional repair.
Verify that you are attempting to connect to the correct R1234yf low-side filling port. Ensure you are not trying to connect to an R134a fitting, as this hose is specifically designed for R1234yf.
Ensure the engine and AC compressor are running. Readings are only valid while the system is under pressure. Note that the gauge needle does not automatically re-zero after use.
Ensure the can is securely attached to the hose and the hose is properly connected to the AC port. Follow the instructions for deploying the contents.
Compatibility Check: Before purchase, confirm your vehicle uses the R1234yf refrigerant. Check under the bonnet for labels or consult your vehicle manual. You must also be able to identify the low-side filling port. This kit is not compatible with R134a systems.
Safety Precautions: Always wear safety goggles and gloves when working on AC systems. Never wear loose clothing around a running engine.
Setup: Ensure the vehicle's engine and AC compressor are running and switched on.
Care: The professional hose and gauge are reusable. Store them in a clean, dry place. Cans have a 1/2 inch coarse right-hand ACME thread and work with the supplied hose.
Important Note: Do not vacuum the AC system before use. Do not try to force the hose onto an R134a fitting.
