Lichamp A2L refrigerant charging hose 1/4 inch 5 ft – left‑hand flare, tool‑free brass fittings for R32/R454B

Lichamp A2L 1/4" refrigerant charging hose is a 5 ft, left-hand-thread service line built specifically for A2L refrigerants like R32 and R454B, offering tool-free connections and a high-strength, leak-resistant design.

Designed for HVAC technicians, refrigeration professionals, and advanced DIYers working with mildly flammable (A2L) refrigerants, this hose balances safety, flexibility, and durability. It combines a 1/4-inch SAE left-hand flared fitting for A2L compatibility with a standard right-hand thread on the opposite end, making it easy to integrate into existing charging setups. Constructed from high-grade rubber and brass with PTFE seals, the hose is rated for demanding pressure and temperature ranges to handle service and charging tasks in tight spaces.

How does this hose make charging R32 and R454B easier?

The Lichamp A2L hose is tailored for A2L refrigerants by using a left-hand flared thread where required, preventing cross-connection errors. A 45-degree angled end and a deeply knurled coupling nut enable quick hand-tight connections without tools, reducing setup time on the job.

• 1/4" SAE left-hand flared thread for A2L refrigerants
• 45° angled fitting for better access in cramped areas
• Knurled coupling nut for reliable, tool-free tightening
• 5 ft length for reach into engine bays or crowded HVAC cabinets

Is the hose durable enough for tough service conditions?

This hose is built to withstand heavy use with a 4000 PSI burst rating and 800 PSI working pressure, delivering robust performance under pressure. Materials were selected for longevity: a reinforced rubber body, brass fittings, and PTFE seals minimize wear and reduce leak risk over repeated cycles.

• 4000 PSI burst pressure and 800 PSI working pressure
• High-grade rubber body resists abrasion and kinking
• Brass fittings for corrosion resistance and mechanical strength
• PTFE end seals for superior leak prevention

Can this hose handle different jobsite temperatures and environments?

The Lichamp hose operates across a broad temperature window from -20°F to 180°F, making it suitable for both cold storage rooms and warm outdoor jobs. Its construction remains reliable in automotive engine compartments, commercial refrigeration units, and field HVAC equipment.

• Safe operating range: -20°F to 180°F
• Resists temperature-related softening or hardening
• Flexible enough for confined-space maneuvering
• Suits residential, commercial, and automotive applications

What safety and compatibility features should technicians know?

The hose is explicitly configured for A2L refrigerants to reduce the risk of mismatching fittings. Leak-resistant PTFE seals, reliable brass connectors, and a clear left-hand/right-hand thread convention help ensure correct, secure connections during charging and maintenance.

• Left-hand thread prevents accidental use with non-A2L service lines
• PTFE seals reduce fugitive emissions and improve service life
• Knurled nut allows secure hand-tight connections for quick swaps
• Yellow jacket improves visibility on busy work sites

Who this is for: HVAC technicians, refrigeration service professionals, and experienced DIYers who work with R32, R454B, or other A2L refrigerants and need a dependable, easy-to-use charging hose. It’s particularly useful for jobs that require maneuvering into tight engine bays or equipment racks where a short, flexible, leak-resistant hose with proper A2L threading is essential.
