R410A Specialist Hoses - 1/2"-20UNF

R410A Specialist Hoses - 1/2"-20UNF Japanese Standard

Specialist charging hoses designed specifically for R410A refrigerant systems with 1/2"-20UNF Japanese standard fittings. Engineered to handle the higher operating pressures associated with R410A applications in residential and light commercial air conditioning systems.

Key Features

• R410A specific design — Engineered for higher-pressure R410A refrigerant systems
• 1/2"-20UNF Japanese standard fittings — Correct connections for R410A equipment
• High-pressure rated — Handles R410A operating pressures up to 56 Bar
• Colour-coded identification — Red (high-pressure), blue (low-pressure), yellow (centre port)
• Multiple lengths — 90cm and 150cm options for various applications
• Professional construction — Durable materials built for daily R410A service work

Why R410A Requires Specialist Hoses

Higher Operating Pressures

R410A operates at significantly higher pressures than older refrigerants like R22:

• R410A high-side pressure: up to 490 PSI (34 Bar)
• R410A low-side pressure: up to 280 PSI (19 Bar)
• Standard hoses may not be rated for these pressures
• R410A-specific hoses ensure safe, reliable operation

Japanese Standard Fittings

Many R410A systems, particularly Japanese-manufactured equipment, use 1/2"-20UNF fittings instead of standard 1/4" SAE fittings. These specialist hoses ensure:

• Proper connection to R410A equipment
• Leak-free sealing at high pressures
• Compatibility with Japanese-manufactured air conditioning systems
• Professional-grade service capabilities

Applications

• Residential air conditioning — R410A split systems and heat pumps
• Light commercial A/C — Small commercial R410A installations
• Japanese equipment — Daikin, Mitsubishi, Fujitsu, and other Japanese brands
• R410A diagnostics — Pressure testing and system analysis
• R410A charging — Refrigerant charging and recovery operations

Available Configurations

• Individual hoses — Red, blue, or yellow in 90cm or 150cm lengths
• 3-piece sets — Complete matched sets for manifold gauge setups
• Adapter hoses — Convert between 1/2"-20UNF and standard 1/4" SAE fittings

R410A vs Standard Hoses

Important Notes

• Not interchangeable: R410A hoses with 1/2"-20UNF fittings are not compatible with standard 1/4" SAE equipment without adapters
• Pressure critical: Always use hoses rated for R410A pressures when servicing R410A systems
• Equipment specific: Check your R410A equipment specifications to confirm fitting type required
