Fieldpiece HV1 Vacuum Hose 3/8" × 3/8" (1.5 m)

Fieldpiece HV1 — a professional 1.5 m (5 ft) vacuum hose with 3/8" × 3/8" fittings, designed specifically for fast, safe, and efficient evacuation of air conditioning, refrigeration, and heat pump systems (HVAC/R). The larger 3/8" diameter offers significantly lower flow resistance than standard 1/4" hoses, dramatically reducing the time needed to achieve a deep vacuum.

Applications

• Evacuation (moisture and air removal) of large commercial and residential HVAC/R systems
• Fast refrigerant recovery and direct connection of vacuum pumps to the system or valve core removal tools (e.g. Fieldpiece VC1E / VC1G)
• Deep-vacuum work where eliminating moisture and air infiltration is critical
• Service and installation of systems operating on conventional refrigerants and modern A2L refrigerants (e.g. R32, R1234yf)

Key features

• High flow capacity — 3/8" bore — the larger internal diameter eliminates bottlenecks in the vacuum circuit, allowing full use of the vacuum pump's capacity and reducing on-site evacuation time.
• Full-ring triple crimp fittings — each hose end is factory-crimped with a full triple-ring ferrule, guaranteeing exceptional leak integrity and pull-out resistance against high vacuum.
• SAE J2196 compliant (anti-permeation barrier) — the hose material is engineered to minimize permeation of air molecules and water vapor through the hose wall during evacuation, ensuring stable, accurate micron gauge readings.
• High pressure rating — 800 psi (55 bar) working pressure and an extreme burst pressure of 4,000 psi (276 bar) for safe use under any conditions.
• A2L refrigerant compatible — safe for use with new mildly flammable refrigerants, making it a versatile tool for modern HVAC/R service.
