Heavy-Duty High-Pressure Hoses

Professional-grade heavy-duty charging hoses with nylon barrier construction rated to 41-56 Bar working pressure. Engineered for demanding HVAC/R applications requiring superior durability and pressure resistance.

Key Features

• Nylon barrier construction — Enhanced durability and permeation resistance
• High working pressure — 41-56 Bar (600-800 PSI) rating for demanding applications
• Grade 5 specification — Professional-grade materials and construction standards
• Colour-coded options — Red, blue, yellow, and black configurations
• Multiple lengths — 90cm to 500cm available for any application
• 1/4" SAE fittings — Universal compatibility with standard equipment

Nylon Barrier Technology

The nylon barrier layer provides superior protection against refrigerant permeation compared to standard rubber hoses. This construction:

• Reduces refrigerant loss — Nylon barrier prevents refrigerant from permeating through the hose wall
• Extends hose life — Superior resistance to degradation from refrigerants and oils
• Maintains flexibility — Remains flexible even after extended use in harsh conditions
• Handles higher pressures — Reinforced construction supports 41-56 Bar working pressure
• Meets environmental standards — Reduced emissions comply with modern refrigerant regulations

Grade 5 Specification

Grade 5 hoses represent the highest quality standard for HVAC/R charging hoses:

• Superior materials and construction
• Enhanced pressure resistance
• Improved permeation resistance
• Longer service life
• Professional-grade performance

Applications

Ideal for high-pressure refrigerant systems, commercial refrigeration installations, R410A air conditioning systems, demanding field service environments, and applications where hose durability is critical. Perfect for technicians who need reliable performance in challenging conditions and high-pressure scenarios.

When to Choose Heavy-Duty Hoses

• High-pressure systems — R410A and other high-pressure refrigerants
• Commercial applications — Intensive daily use in professional environments
• Long-term installations — Permanent or semi-permanent hose setups
• Harsh conditions — Extreme temperatures or demanding field service
• Regulatory compliance — Applications requiring low-permeation hoses
