Ritchie Engineering 19158 Refrigerant Coupler 1/2 Acme X 14mm

Product Description

The RITCHIE ENGINEERING 19158 is a brass refrigerant coupler designed to connect 1/2 inch Acme female fittings to 14 mm male fittings on refrigerant recovery, charging, and manifold gauge equipment. The coupler measures 8.25 inches in length and is manufactured from brass with a bronze color finish. It is compatible with all CFC, HCFC, and HFC refrigerants, making it a versatile adapter for HVAC service work. Licensed HVAC technicians use this fitting when adapting between Acme-threaded manifold hose connections and 14 mm metric fittings commonly found on recovery machines and European-standard service equipment.

This coupler is suited for both residential and light commercial HVAC service applications. It bridges the gap between 1/2 inch Acme-threaded hose ends and 14 mm male connections on refrigerant handling equipment. Technicians performing refrigerant recovery, evacuation, or system charging will find this adapter useful when working with mixed connection standards on the service bench or in the field. Its all-refrigerant compatibility means a single fitting covers R-22, R-410A, R-134a, and other common CFC, HCFC, and HFC refrigerants without restriction.

Key Features

• 1/2 inch Acme female inlet x 14 mm male outlet connection
• Compatible with all CFC, HCFC, and HFC refrigerants
• Brass construction for corrosion resistance and long service life
• Bronze color finish for easy identification in the tool kit
• 8.25 inch overall length provides reach in tight service connections

Compatibility

Designed for use with refrigerant manifold gauge sets, recovery machines, and service hoses using 1/2 inch Acme female connections on one end and 14 mm male connections on the other. Compatible with all CFC, HCFC, and HFC refrigerant systems.

Installation Notes

Installation should be performed by a licensed HVAC technician holding an EPA Section 608 certification. Before connecting or disconnecting refrigerant fittings, recover system refrigerant per EPA regulations and confirm the system is at safe working pressure. Hand-tighten Acme fittings first, then snug with an appropriately sized wrench — do not overtighten brass fittings as this can damage threads. Inspect the coupler and mating fittings for debris or damage before each use to prevent refrigerant leaks.
