The Mastercool 40396 hose set is a 244 cm (96″) Grade 5, 1/4″ SAE blue/yellow/red trio built for everyday HVAC/R charging and recovery. Knurled brass nuts and 8-segment crimps keep things tight so you can crack on with the job—no worries.

Key Features & Trade Benefits

• Grade 5 construction (Standard & Nylon Barrier options) — engineered for durability and higher duty cycles; fewer weeping swivels and call-backs.
• 1/4″ × 1/4″ SAE fittings — fits most legacy manifolds and service ports; easy drop-in for existing kits.
• Knurled brass nuts — quick finger-tightening even with gloves; faster bottle swaps.
• 8-segment crimp ferrules — secure, repeatable seal for long service life; bloody good under rough site handling.
• Compliance focused — built to meet EPA, SAE & UL refrigerant containment requirements.
• Pressure ready — Standard hoses typically 750 PSI WP / 3000 PSI burst; Nylon Barrier typically 800 PSI WP / 4000 PSI burst (model dependent).

Why This Product Matters

Real-world: Up on a Sydney roof in 40-degree heat, we swapped a tired set for the 40396. The knurled nuts bit nicely, the crimps didn’t twist when we cracked the valves, and vacuum held steady—she’ll be right when your hoses don’t creep under load.

Pro Tip

Working on R410A/R32 splits? Many service ports are 5/16″ SAE. Keep a 5/16″ adapter or hose set in the van to avoid a second trip. Pair these hoses with a quality manifold to confirm pressures before and after charging.

Compatibility & System Info

• Set contents: 3 hoses — blue (low), red (high), yellow (service), 244 cm (96″), 1/4″ × 1/4″ SAE.
• Typical use: charging, recovery and service on domestic & light-commercial systems.
• Pressure ratings: see model-specific ratings; standard ≈ 750/3000 PSI; nylon barrier ≈ 800/4000 PSI.
• Standards: designed to meet EPA/SAE/UL requirements for refrigerant containment.

Local note: From humid Brisbane plant rooms to windy Sydney rooftops, the 244 cm length gives you working room without tugging the manifold—too easy.

FAQs

Will these fit my existing manifold?
Yes — these are 1/4″ SAE. If your system uses 5/16″ ports (common on R410A/R32), add a 5/16″ coupler/adapter.

Are they suitable for high-pressure work?
Yes — for higher duty, consider Nylon Barrier models (≈ 800 PSI WP / 4000 PSI burst). Always check the nameplate and manufacturer specs.

Do they meet industry standards?
The range is built to meet EPA/SAE/UL containment requirements; verify on your chosen variant.
