Icp qc-a2l-lh45 A2L Left-hand Thread Adapter 45 Degree

Product Description

The INTERNATIONAL COMFORT PRODUCTS qc-a2l-lh45 is a left-hand thread refrigerant adapter engineered for use with A2L refrigerants. It features a 45-degree angle configuration with a 1/4-inch female flare inlet and a 1/4-inch male flare outlet. The left-hand thread design is a safety-standard requirement specific to A2L mildly flammable refrigerant systems, preventing accidental cross-connection with standard right-hand fittings. This adapter is installed by licensed HVAC technicians during system service, recovery, or charging operations on equipment using A2L refrigerant blends.

This adapter is intended for HVAC service applications where A2L refrigerants are in use, including newer residential and light commercial split systems and heat pumps that have transitioned to lower-GWP refrigerant blends. It is used at the service port connection point during refrigerant handling procedures and is compatible with standard 1/4-inch flare service equipment modified or designated for A2L use.

Key Features

• Left-hand thread design meets A2L refrigerant safety standards to prevent cross-connection with conventional fittings
• 45-degree angle orientation for improved access in tight service port locations
• 1/4-inch female flare x 1/4-inch male flare connection for compatibility with standard HVAC service hose fittings
• Designed specifically for A2L mildly flammable refrigerant service work

Compatibility

Designed for use with HVAC systems charged with A2L refrigerants requiring left-hand thread service fittings per current industry safety guidelines.

Installation Notes

Installation should be performed by a licensed HVAC technician with proper certification for handling A2L refrigerants. Always recover refrigerant and depressurize the service circuit before connecting or disconnecting fittings. Use only tools and hoses rated and designated for A2L refrigerant service to avoid contamination or unsafe conditions. Follow all applicable local codes and refrigerant handling regulations during service.
