Customizable Easy to Install Efficient Flow Superior Sealing

AC Coupling

Craft’s patented (US 20240328554A1) self-sealing brass couplings allow for charging the refrigeration, air conditioning, and heat pump systems without the use of brazing. These couplings are extremely easy to use and are compatible with a wide range of refrigerants. Such as R290, R454C, R410A, R448A, R449a, R513A, R134a, R407C and more… They range from 1/4” – 3/4”, and the connections are customizable to the core. 

The only coupling that works with A3 (R290) refrigerants and is UL listed.

Let's talk about the benefits

Corrosion Resistant

Brass body and the copper connection reduces the chances of corrosion and improves durability. 

Efficient

Designed to perform well under low pressure drops to improve overall system efficiency.

Easy Connect & Disconnect

The brass threaded design make the connection and disconnection while under pressure. These couplings can be connected and disconnected without loss of any refrigerant. 

Installation

Customized copper sweat connections simplify the factor installed processes by eliminating brazing, flux residue clean up saving you money and time.

Sealing

Our patented design and technology reduces the refrigerant leak rates. Virtually eliminating the refrigerant loss. 

Reliable

Designed in the USA, and used by major manufacturers worldwide for the past decade. These couplings have gone under stringent testing and qualification process.
