Warranty14-day returnsFieldpiece 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.
