Mastercool High Pressure Hoses

The Mastercool 90262-60 is a 60″ (≈152 cm) Grade 5 hose set with manual shut-off valves for quick, controlled charging and recovery. Built for Aussie tradies who want durability, speed and clean disconnects—fair dinkum value on every call-out.

Key Features & Trade Benefits

• Manual shut-off valve fittings — stop refrigerant flow with a quarter turn; fewer spills and cleaner gauge changes.
• Grade 5 hose construction — proven for service duty; resists kinks and daily rough-and-tumble, cutting down on call-backs.
• 600 PSI working / 3000 PSI burst (standard hose) — confidence for high-demand jobs. Nylon-barrier variants are typically 800/4000 PSI.
• 1/4″ × 1/4″ SAE — fits most manifolds and service ports; easy drop-in to existing kits.
• Knurled brass nuts + 8-segment crimps — quick finger-tightening and a secure, leak-tight seal — bloody good in harsh site conditions.
• Meets EPA/SAE/UL requirements — built to recognised containment standards for refrigerants.
• Colour-coded 3-hose set — blue/yellow/red for tidy, fast ID on the gauges.

Why This Product Matters

Real-world: on a sweaty Brisbane rooftop, a tech cracked the 90262-60 valves shut before disconnecting from a busy manifold. No puff, no mess — just a clean break and back to pressure checks. When job pace matters, shut-off hoses save minutes and mistakes — she’ll be right. If you’re building out a kit, browse our Refrigerant Hoses category.

Pro Tip

Close the valve before cracking a fitting to minimise refrigerant loss and protect gaskets. Working on R410A/R32 gear with 5/16″ ports? Pack an adapter or a 5/16″ hose set to avoid a second trip. Too easy.

FAQs

Are these ball-valve style shut-offs?
Yes — Mastercool’s straight manual shut-off valves use a ball-valve design for quick control and one-hand operation.

Do these meet industry standards?
The range is built to meet EPA, SAE and UL requirements for refrigerant containment.

What if I need higher pressure ratings?
Consider nylon-barrier variants in the Mastercool range (typically 800 PSI WP / 4000 PSI burst).
