Fieldpiece HR3CM 5/16" Service Hose Set with Ball Valve

Fieldpiece HR3CM — a professional three-hose service set (red, blue, yellow), 1.5 m (5 ft) long with 5/16" SAE fittings (female, 45° angled with valve) on one end and 1/4" SAE (female, straight) on the other. Designed for modern mini-split air conditioning and heat pump systems, it combines exceptional mechanical durability with advanced low-loss protection. Each hose features an integrated Low Loss valve and a manual ball valve angled at 45° for comfortable use in tight spaces.

Applications

• Safe refrigerant charging of mini-split air conditioning systems, heat pumps, and refrigeration installations (compatible with A2L refrigerants such as R32, R1234yf, and standard HFC/HCFC including R410A).
• Fast, safe refrigerant recovery without risk of releasing refrigerant to atmosphere.
• Precise system evacuation on HVAC/R installations.
• Pressure diagnostics without risk of refrigerant frostbite.

Key features

• Dual shut-off and full control — integrated Low Loss valve at the system fitting combined with the manual ball valve gives precise flow control and completely prevents refrigerant escape when disconnecting.
• Mini-split hoses (5/16" to 1/4") — the 5/16" SAE fitting on the angled end connects directly to modern mini-split systems without leak-prone adapters.
• High pressure rating (800 / 4,000 psi) — safe operation at up to 800 psi (approx. 55 bar) working pressure; burst pressure 4,000 psi (approx. 275 bar).
• SAE J2196 neoprene anti-permeation barrier — multi-layer hose structure minimizes refrigerant permeation through the rubber, meeting stringent environmental standards.
• Triple-crimp ferrule — reinforced triple-crimp at each hose end provides outstanding pull-out and flex resistance under high pressure.
