Refrigerant Charging Hoses for HVAC & Refrigeration

Professional-grade refrigerant charging hoses for air conditioning, commercial refrigeration, and automotive A/C service. The complete Mastercool hose range in stock — standard 1/4" SAE, ball valve, heavy-duty high-pressure, R410A specialist, R1234yf, and ACME configurations. Colour-coded red, blue, yellow, and black. Same-day dispatch from UK stock.

Standard Charging Hoses — 1/4" SAE

The trade standard for refrigerant service across R134a, R404A, R407C, R22, and compatible refrigerants. Available in red (high-side), blue (low-side), and yellow (service/manifold) in lengths from 30cm to 15m. Meets EPA, SAE, and UL requirements. Browse the full range under Standard Charging Hoses.

Ball Valve Charging Hoses

Ball valve hoses provide positive shut-off at the hose end — eliminating refrigerant loss when disconnecting from service ports. Recommended for R410A and R32 systems where minimising refrigerant release is essential for F-Gas compliance. Browse under Ball Valve Charging Hoses.

Heavy-Duty High-Pressure Hoses

Reinforced high-pressure hoses for demanding commercial refrigeration applications and high-side R410A service work. Rated for higher working pressures than standard charging hoses. Browse under Heavy-Duty High-Pressure Hoses.

Specialist Hoses

R410A specialist hoses with 1/2"-20UNF fittings for high-side connections. R1234yf specialist hoses with 12mm M fittings for next-generation AC systems. ACME fitting hoses for refrigerant cylinder connections. Complete 3-piece matched hose sets for engineers equipping a new manifold. Capillary hoses for thermoplastic gauge connections.

Choosing the Right Hose

Match hose fitting size to your manifold — standard 1/4" SAE for most manifolds, 1/2"-20UNF for R410A high-side, 12mm M for R1234yf. Use vacuum-rated large-diameter hoses when evacuating with a vacuum pump to reduce evacuation time. Replace hoses showing signs of cracking, swelling, or fitting wear — a leaking hose causes refrigerant loss and inaccurate pressure readings.
