Engineered specifically for heavy-duty HVAC and refrigeration plumbing, our Premium Copper ACR Reducing Couplings provide a secure, leak-proof transition between two copper tubes of different diameters. Manufactured from high-purity seamless copper, these solder fittings are built to handle intense system pressures, high vibration, and extreme temperature changes.
Every reducing fitting features precision-machined capillary ends that ensure a uniform solder or braze flow, creating a permanent mechanical bond that keeps your refrigerant loop sealed tight while changing line sizes.
Key Features and Benefits
ACR Grade Cleanliness: Manufactured to strict ASTM B280 standards. Each reducing coupling is thoroughly cleaned, degreased, and individually bagged or sealed to guarantee zero internal oil, dust, or moisture before brazing.
High-Pressure Reliability: Fully compliant with ASME B16.22 dimensions, making them strong enough to safely handle high-pressure refrigerants like R410A, R32, and R290.
Pure C12200 Copper: Formed from 99.9 percent pure deoxidized copper. This offers maximum corrosion resistance, excellent thermal conductivity, and structural longevity.
Perfect Capillary Flow: Designed with strict dimensional tolerances. The smooth inner sockets allow solder or brazing alloy to pull in evenly via capillary action, preventing voids and joint failure.
Smooth Diameter Transition: The tapered, wrought-copper design minimizes flow restriction and turbulence, maintaining proper refrigerant velocity and system efficiency through the size change.
