This Mastercool full-flow 3/8″ SAE charging hose (150 cm, black) is built from Grade 5 hose for tough, daily HVAC work. Knurled brass nuts and an 8-segment crimp deliver a tight, repeatable seal, so you can crack on with charging or recovery—no worries. A longer 180 cm variant is available if you want extra reach.

Key Features & Trade Benefits

• Grade 5 construction (Standard or Nylon Barrier) — engineered for high-pressure use and long life; fewer weeping swivels and call-backs.
• Full-flow 3/8″ bore — reduces restriction vs 1/4″ lines, helping faster movement of refrigerant when the task allows.
• Knurled brass nuts — quick finger-tightening, even with gloves; faster bottle swaps and connections.
• 8-segment crimp ferrules — secure, leak-tight joint for rough site handling; bloody good reliability.
• EPA/SAE/UL containment focus — peace of mind your hose is built to meet recognised industry standards.
• Two lengths — 150 cm for compact jobs; optional 180 cm (Model 94172) for extra reach.

Why This Product Matters

Real-world: on a humid Brisbane arvo, the crew swapped a tired 1/4″ line for a full-flow 3/8″ hose on a recovery job. With less restriction, the process ticked along smoother and the joints stayed bone-dry thanks to those knurled nuts—she’ll be right when your hose isn’t the bottleneck. If you’re comparing options, see the Refrigerant Hoses category.

Pro Tip

Match hose size to the task. Use 3/8″ full-flow for higher-volume work where permitted; keep a shorter hose to minimise pressure drop. And always replace perished gaskets when you see micro-bubbles on a leak test—cheap insurance for a ripper seal.

Compatibility & System Info

Local Job Note

Whether you’re working windy rooftops in Sydney or muggy plant rooms in Brisbane, the 150 cm line gives tidy routing without dragging the manifold—too easy.

FAQs

Will a 3/8″ hose help with faster work?
A larger bore can reduce restriction vs 1/4″ hoses, which helps on certain charging/recovery tasks. Keep hoses as short as practical to minimise pressure drop.

Is there a longer option?
Yes — the 180 cm Mastercool 94172 offers extra reach for trickier layouts.

Does this fit my manifold?
Check your port size: this hose is 3/8″ SAE. If your manifold uses 1/4″ or 5/16″ ports, use the appropriate adapter or hose set from our Refrigerant Hoses range.
