Aurobest Refrigerant Load Hose Set is a set of air conditioning maintenance hoses designed for reliable refrigerant charging and service. Colour-coded hoses and robust brass fittings make topping up R134a systems less stressful for DIYers and technicians. Will the build and fittings stand up to frequent garage use?
⚡ At a Glance
- • Working Pressure: Rated working pressure 600 PSI with a 3000 PSI burst rating
- • Best for: DIYers and garage technicians handling R134a charging and basic aircon maintenance
- • Not ideal for: Specialist refrigerant systems that use non‑R134a fittings or non‑SAE threads
Three 1.5m hoses with brass and rubber construction, supplied in red, yellow and blue. 1/4 SAE connectors suit R134a applications for car and home air conditioners.
Secure connections - with deep‑knurled brass nuts
Solid brass nuts use a deep knurl design and a six‑sided clamp to create a robust mechanical grip on the hose end. Hand tightening is possible while the brass material resists deformation under repeated use.
Reliable seals reduce leakage risk during charging and maintenance, giving confidence when working under pressure. Faster hookups mean less fumbling in busy workshop conditions.
High‑pressure handling - with a 600 PSI working rating and 3000 PSI burst rating
Hoses are rated to 600 PSI for normal operation and tested to a 3000 PSI burst level, reflecting reinforced rubber construction. The ratings indicate suitability for the pressures encountered in typical R134a systems.
Safe use across a wide range of service scenarios without premature failure. Durable construction supports repeated top‑ups and routine maintenance tasks.
Quicker, less error‑prone charging - with a colour‑coded three‑hose setup
Three hoses come in red, blue and yellow with 1/4 SAE connectors; recommended connections are blue to low pressure, red to high pressure and yellow for refrigerant supply. Colour coding follows common workshop practice for rapid identification.
Reduced chance of swapping connections speeds up servicing and lowers the risk of incorrect hookups. Helpful for technicians working on multiple vehicles or in low‑light conditions.
✨ The 4 Key Reasons for Aurobest Refrigerant Load Hose Set
- Deep‑knurled brass nuts - Ensure firm, hand‑tightened connections for quick setup
- Six‑sided clamp design - Maintains a secure hose‑to‑fitting bond under load
- 1.5m hose length - Reaches across most engine bays and outdoor condenser units
- Colour‑coded set - Cuts connection errors and speeds up routine servicing

❓ Frequently Asked Questions
Q: Are these hoses compatible with R134a refrigerant?
A: Yes, the hoses are specified as suitable for R134a applications and are intended for refrigerant charging and air conditioning maintenance.
Q: What size fittings do the hoses use?
A: Both ends use 1/4 SAE thread connectors; the description notes that 1/4 SAE is a thread specification and not a 1/4 inch diameter.
Q: How durable are the fittings under pressure?
A: Brass nuts with a deep knurl design and a six‑sided clamp provide a reliable connection, and the hoses are rated to 600 PSI working pressure with a 3000 PSI burst rating.
🏆 Our Verdict
The Aurobest Refrigerant Load Hose Set suits DIYers and small workshops that regularly service R134a air conditioning systems. Colour coding combined with brass nuts and reinforced hoses makes charging faster and reduces connection errors. Robust construction and high pressure ratings point to strong long‑term value for routine maintenance tasks.
