R32 R410A Manifold Hose Fittings Checklist Uk
Direct answer: before a UK R32 or R410A job, verify the hose kit, not just the manifold body. Many modern AC service-port setups need 5/16in connections even when the manifold block or charging hose uses 1/4in SAE fittings.
Most wasted trips here are not caused by the wrong screen. They are caused by assuming the hose ends in the box match the unit waiting on site.
Common hose-end combinations to check
| Hose or fitting | Common role | Buyer check |
|---|---|---|
| Red and blue 1/4in to 5/16in hoses | High and low side connection on many R32/R410A AC setups. | Confirm both ends and shut-off style before checkout. |
| Yellow 1/4in to 1/4in hose | Charging, recovery or service path depending on procedure. | Confirm length, rating and cylinder/tool connection. |
| 5/16in adaptors | Bridge between manifold/hose inventory and service ports. | Carry spares only if they are rated and appropriate for the task. |
| Spare gaskets | Prevent small leaks at repeated connections. | Keep a small service pack in the case. |
Evidence that the detail matters
A UK hose pack listing from UK R32/R410A hose pack listing describes red and blue hoses with 1/4in-to-5/16in ends and a yellow hose with 1/4in ends. SRW's A2L manifold listing highlights swappable 1/4in and 5/16in fittings, and the SRW manifold gauge buying guide includes hose quality, anti-blowback fittings and connection sizes as buying factors.
Checkout checklist
- Photograph the unit nameplate and service ports before ordering.
- Match each hose end to the manifold, equipment port and cylinder or recovery path.
- Confirm the pressure rating from the hose datasheet or seller listing; hose colour alone is not a safe rating check.
- Check whether ball valves or anti-blowback fittings are included or separate.
- Carry spare gaskets and caps that fit your actual hoses.
- Keep contamination discipline between refrigerants according to your company procedure.
When to pause
Pause if the listing shows only the gauge body, if the accessory photograph is generic, if it says “compatible” without a carton list, or if you are buying an automotive kit and the couplers are not explicitly confirmed. Compatibility of the instrument is not the same as completeness of the connection kit.
Conditional next step
If a two-valve digital manifold fits your workflow and the seller confirms the hose/fitting package for your R32/R410A jobs, compare a same-site option such as the DMG-2SE product page. If connection details are missing, ask for the box contents before booking the job around it.
