Icp qc-a2l-lh A2L Left-hand Thread Adapter 1/4 in Flare

Product Description

The INTERNATIONAL COMFORT PRODUCTS qc-a2l-lh is a straight refrigerant adapter designed for use with A2L low-GWP refrigerant systems. It features a 1/4-inch female flare inlet and a 1/4-inch male flare outlet with left-hand thread on the A2L side, a physical safety standard that prevents accidental cross-connection with conventional right-hand-thread refrigerant fittings. This adapter is installed by licensed HVAC technicians during system service, recovery, or charging procedures on equipment using A2L classified refrigerants such as R-32 or R-454B.

This adapter is suited for residential and light commercial HVAC systems that use A2L mildly flammable refrigerants. It fits into the service workflow anywhere a transition is needed between A2L left-hand-thread service ports and standard 1/4-inch flare manifold gauges, recovery equipment, or charging hoses. Correct use of this adapter supports compliance with updated refrigerant handling procedures as the industry transitions to lower-GWP refrigerants under current EPA and ASHRAE guidelines.

Key Features

• Left-hand thread on A2L side prevents cross-connection with conventional refrigerant service fittings
• Straight configuration — 1/4-inch female flare inlet to 1/4-inch male flare outlet
• Designed specifically for A2L refrigerant service applications
• Supports safe service transitions during the industry shift to lower-GWP refrigerants

Compatibility

Designed for use with A2L refrigerant systems requiring a left-hand thread to standard 1/4-inch flare adapter during service, recovery, or charging operations.

Installation Notes

Installation should be performed by an EPA Section 608 certified HVAC technician familiar with A2L refrigerant handling requirements. Recover all refrigerant and relieve system pressure before connecting or disconnecting any refrigerant fittings. Do not overtighten flare connections — use appropriate flare wrenches and follow the equipment manufacturer torque guidance where provided. Always verify left-hand thread engagement before applying torque to avoid fitting damage.
