ACME Fitting Hoses - 1/2" ACME x 14mm
ACME Fitting Hoses - 1/2" ACME x 14mm
Specialist charging hoses with 1/2" ACME x 14mm fittings designed for direct connection to disposable refrigerant cylinders and recovery equipment. Eliminates the need for adapters when connecting to ACME-threaded cylinders, providing faster, more efficient refrigerant charging and recovery operations.
Key Features
- 1/2" ACME fittings — Direct connection to disposable refrigerant cylinders
- 14mm opposite end — Standard connection to manifold gauges or equipment
- No adapters required — Eliminates connection points and potential leak sources
- Colour-coded options — Red, blue, and yellow for easy identification
- Multiple lengths — 300cm to 750cm for various applications and access requirements
- Professional construction — Durable materials built for repeated cylinder connections
What is ACME Thread?
ACME thread is a trapezoidal screw thread commonly used on disposable refrigerant cylinders. The 1/2" ACME fitting provides:
- Quick connection — Fast, tool-free attachment to cylinders
- Secure seal — Reliable, leak-resistant connection
- Industry standard — Used on most disposable refrigerant cylinders
- Robust design — Withstands repeated connection/disconnection cycles
Why Choose ACME Fitting Hoses?
Faster Service
Direct cylinder connection eliminates the need for adapters, reducing setup time and potential leak points. Simply thread the ACME fitting onto the cylinder and you're ready to charge or recover.
Fewer Leak Points
Every connection point is a potential leak source. ACME fitting hoses eliminate the adapter connection, reducing leak risk and refrigerant loss during service operations.
More Efficient Workflow
Particularly valuable for mobile service technicians who frequently connect and disconnect from refrigerant cylinders. ACME hoses streamline the workflow and reduce service time.
Applications
- Disposable cylinder charging — Direct connection to 1/2" ACME threaded cylinders
- Mobile service work — Faster cylinder connections for field technicians
- Recovery operations — Connect recovery machines to ACME-threaded equipment
- High-volume charging — Larger diameter improves flow rates
- Commercial refrigeration — Bulk refrigerant handling and system charging
Compatible Refrigerants
ACME fitting hoses are suitable for use with:
- R134a (most common on disposable cylinders)
- R404a
- R407C
- R22 (where still permitted)
- Other common refrigerants available in ACME-threaded cylinders
Available Configurations
- Red hoses — High-pressure side connections
- Blue hoses — Low-pressure side connections
- Yellow hoses — Centre port / cylinder connections
- 300cm (10ft) — Standard length for most applications
- 500cm (16ft) — Extended reach for difficult access
- 600cm (20ft) — Long-reach applications
- 750cm (25ft) — Maximum reach for large commercial systems
ACME vs Standard Hoses
| Feature | Standard 1/4" SAE | ACME 1/2" x 14mm |
|---|---|---|
| Cylinder connection | Requires adapter | Direct ACME thread |
| Connection speed | Slower (adapter needed) | Faster (direct) |
| Leak points | More (adapter adds connection) | Fewer (no adapter) |
| Flow rate | Standard | Higher (larger diameter) |
| Best for | Manifold gauge work | Cylinder charging/recovery |
Professional Tips
- Check thread condition: Inspect ACME threads on cylinders before connection
- Hand-tighten only: ACME fittings should be hand-tight — no tools required
- Keep threads clean: Debris in threads can cause leaks
- Store properly: Protect ACME fittings when not in use to prevent thread damage
