Refrigerant Hoses | 1/4, 5/16 & 3/8 HVAC Hoses

Refrigerant Hoses for Charging, Service & Evacuation

Shop refrigerant hoses for day-to-day HVAC/R service, charging and evacuation work across Australia. This collection suits technicians, apprentices, maintenance teams and informed buyers who need the right hose size, fitting and pressure capability for the job without guessing in a generic tool aisle.

You’ll find standard hoses and couplings, high-pressure options for modern split systems, and wide-bore evacuation hoses for faster pull-downs. If you also need matching test gear, browse our refrigerant gauges and recovery & evacuation tools.

How to choose the right refrigerant hose

• Start with the port size: 1/4" SAE is common for many legacy and general service setups, 5/16" SAE is common on modern R410A and R32 split systems, and 3/8" hoses are typically chosen for higher-flow evacuation work.
• Match the application: charging hoses, service hoses and evacuation hoses are not all doing the same job. Use a dedicated evacuation hose where speed and vacuum performance matter.
• Check the hose ends: some sets are 1/4" x 1/4", while others mix 1/4" and 5/16" ends to suit manifolds, adapters and mini-split service ports.
• Look at control features: ball valves and low-loss fittings help reduce refrigerant loss and make disconnects tidier on site.
• Confirm the rating on the product page: high-pressure refrigerants and modern systems need hose sets rated for the work you’re doing.

Quick size guide

• 1/4" SAE hoses: a common everyday size for charging and service work on many HVAC/R and automotive-style setups.
• 5/16" SAE hoses: a common choice for R410A and R32 mini-split service ports and related high-pressure workflows.
• 3/8" evacuation hoses: better suited to deep vacuum work where you want less restriction and a faster pull-down.

What you’ll find in this collection

• Standard 3-hose charging sets in common service lengths
• 5/16" hose sets for modern split-system ports
• Wide-bore evacuation hoses for vacuum work
• Colour-coded red, blue and yellow sets for easier field use
• Options from trusted brands including Mastercool, Imperial and Robinair

Top picks from this range

• Mastercool 90cm Hose Set of 3 49336-JT – a strong match for technicians working on modern R410A and R32 split systems with 5/16" service ports.
• Imperial 90cm 500 Series Evacuation Hose 3/8" – a better option when the job is evacuation rather than routine charging and you want a wider hose path.
• Robinair 180cm Hose Set of 3 1/4" 30072 – a longer-reach standard service set for general charging and diagnostic work.

Compatibility and safety notes

Always match the hose, fitting and pressure rating to the refrigerant, the system service port and the specific task. For evacuation, dedicated large-diameter vacuum-rated hoses are the better option than relying on standard service manifolds and narrow charging hoses.

Work involving scheduled refrigerants in Australia must be carried out in line with current refrigerant handling obligations and manufacturer instructions. See the ARCtick Refrigerant Handling Code of Practice and manufacturer guidance such as Mastercool R410A hoses for compatibility and pressure-rating checks.

FAQs

What size refrigerant hose do I need?

That depends on the system port and the job. Many everyday service setups use 1/4" SAE, many R410A and R32 split systems use 5/16" SAE, and evacuation work often benefits from a 3/8" hose.

Are these hoses suitable for R32 and R410A?

Some are, but not every hose in every setup should be assumed suitable. Check the product page for the actual hose ends, rating and intended refrigerant/application before ordering.

Can I use a charging hose for evacuation?

For short, simple jobs you may see people do it, but it is not the preferred setup. Dedicated evacuation hoses are a better choice when you want faster pull-downs and fewer restrictions.

Do I need 5/16" fittings for mini-splits?

Often yes for modern R410A and R32 systems, but always confirm the service-port size on the unit or in the manufacturer documentation.

Should I choose ball-valve hoses or standard hose ends?

Ball-valve hoses can make disconnects cleaner and help reduce losses. Standard hose ends can still be fine where your workflow already uses separate low-loss fittings or couplers.

What else should I buy with refrigerant hoses?

Many buyers also need couplings, refrigerant gauges, or gear from the recovery & evacuation range.
