Mastercool R410A Hoses (Model HSG5) are built for modern high-pressure refrigerants with options for standard or nylon-barrier construction, plus 5/16" and 1/4" connection variants. They’re made for tradies who want fast charging, solid connections and fewer call-backs—no dramas.

Reliable hoses built for R410A (and R32) systems

These R410A Hoses (HSG5) handle high pressures and deliver safe, efficient refrigerant flow. Perfect for techs working on split-systems and light commercial units. Variants include 90 cm and 150 cm sets, plus nylon-barrier low-permeation options.

Key features and benefits

✅ Grade 5 construction — built tough for daily service work; less hose swell and fewer leaks.
✅ Optional nylon barrier — lowers permeation on R410A/R32 so your charge stays put; fewer come-backs.
✅ Knurled brass nuts — easy finger-tightening in tight spots, no spanner needed.
✅ 8-segment crimp — solid, leak-resistant ferrule for a fair dinkum seal.
✅ Compliance-ready — aligns with EPA/SAE/UL requirements for refrigerant hoses (e.g., UL 1963, SAE J2196).
✅ Sets & sizes — choose 3-hose sets in 90 cm or 150 cm; 5/16"×5/16" and 1/4"×5/16" ends available.

Why this product matters

On a summer change-over in Parramatta, we swapped a crew from old, porous hoses to nylon-barrier sets. First pull held vacuum better, charge weights were bang-on, and the team shaved ten minutes off each commissioning. That’s real-world time back in your day—too easy. If you’re comparing options, the refrigerant hoses category gives you a quick view of hose grades and lengths.

Pro Tip

Match the service port size first: many R410A/R32 systems use 5/16" SAE ports. If your manifold or tools are 1/4", grab hoses with 1/4"×5/16" ends (or use an adaptor). Always crack the hose at the manifold to purge air before charging—she’ll be right.

Compatibility & system info

Refrigerants: R410A and R32 (as specified on variants), plus other HFCs as per hose rating.
Connections: 5/16"×5/16" or 1/4"×5/16" SAE flare options.

Standards context: For safe work with higher-pressure/HFC and A2L refrigerants, follow AIRAH’s Refrigerant Handling Codes of Practice (AS/NZS ISO 817 classifications).

Built for Aussie jobsites

Whether you’re charging a multi-split in Sydney’s coastal humidity or doing service runs through Brisbane’s dustier sites, these hoses hold up to hot roofs and rough handling—bloody good value.

FAQs

Q: Are these hoses suitable for R32 as well as R410A?
A: Yes—select the variant marked for R32/R410A (5/16" ends are common on these systems).

Q: Do I need 1/4" or 5/16" hose ends?
A: Many R410A/R32 units use 5/16" service ports. If your gauge set is 1/4", go for the 1/4"×5/16" option to bridge the mismatch—keeps the kit flexible.

Q: What else should I pair with these for charging by weight?
A: A reliable refrigerant scale makes life easier. Check our refrigerant scales for trade-ready options.

Q: Do these hoses meet recognised hose standards?
A: Yes—our hose ranges align with industry standards like UL 1963 and SAE J2196 used for refrigerant containment/permeation. For a standards overview, see AIRAH’s 2024 Refrigerant Handling Codes of Practice.
