Description
Mastercool R410A Nylon-Barrier Hose Set (5/16″ SAE) is built for modern digital manifolds and high-pressure refrigerants like R410A/R32. Grade-5 construction, low-permeation barrier, and knurled brass nuts make installs quick and clean — no dramas on site.
Key Features & Trade Benefits
- 5/16″ SAE ends for R410A service ports — plug straight into most split-system ports used on R410A/R32. Benefit: instant compatibility with digital manifolds.
- Grade-5, nylon-barrier hose — low permeation and high pressure capability. Benefit: less refrigerant loss and tighter jobs.
- 8-segment crimp ferrules — secure, long-life joints. Benefit: durability when hoses get tossed in the ute.
- Knurled brass nuts — easy finger-tightening. Benefit: quicker set-up in tight spaces.
- 56 bar working / 280 bar burst (nylon barrier) — ready for high-pressure work. Benefit: confidence on scorching roof decks.
- Meets typical EPA/SAE/UL requirements — built for trade compliance (e.g., UL 1963, SAE J2196). Benefit: helps your paperwork stack up.
Why This Product Matters
R410A/R32 jobs can be fiddly when your manifold set isn’t matching the 5/16″ ports. These Mastercool hoses bridge the gap so you’re testing and charging in minutes. A tech in Melbourne told us swapping to nylon-barrier 5/16″ hoses cut their nuisance leaks — bloody ripper when you’re chasing a vacuum in summer.

Pro Tip
Many digital manifolds use 1/4″ ports while the system service ports are 5/16″. If you’re mixing gear, add a 1/4″F → 5/16″M adapter at the manifold end — too easy.
Compatibility & System Info
- Variants include 5/16″×5/16″ and 1/4″×5/16″ SAE flare ends; lengths typically 90 cm and 150 cm (sets of 3).
- Suitable for high-pressure refrigerants incl. R410A & R32.
- Complement with 5/16″ Kwik-Couplers for faster, low-loss connections.
Local Jobsite Context (AU)
From tight ceiling spaces in Sydney to mid-day roof work in Perth, low-permeation barrier hoses mean fewer top-ups and tidier results — fair dinkum value for busy crews.

FAQs
Will these hoses make my manifold “R410A-ready”?
Yes — the 5/16″ ends match common R410A/R32 service ports, and nylon-barrier construction suits higher pressures. Check your manifold ports; use a 1/4″F→5/16″M adapter if needed.
Are they suitable for A2L refrigerants like R32?
Yes — Mastercool specifies these for high-pressure refrigerants including R32 (A2L). Always follow site safety and your SWMS.
What length should I choose?
90 cm for tight indoor work; 150 cm for rooftop or awkward access where extra reach helps keep the manifold safe.
