The CoreMax system eliminates process tubes and Schrader valves replacing them with a removable high flow valve. For units with process tubes and Schrader valves you may be able to reduce the cost of your refrigeration unit by replacing them with CoreMax. As a side benefit to eliminating process tubes, you may eliminate one or more brazed joints which are a potential leak path. This revolutionary method gives you the choice of how you want to test, fill and evacuate your systems. Sleeve actuated Design which allows removal and replacement of COREMAX valve core without loss of refrigerant in charged units.
Shortest Processing Time
Processing through the seat with the CoreMax valve removed is the way to evacuate and charge refrigeration systems. Processing through the seat allows for the greatest flow and therefore the shortest processing time. At the evacuation stations the Core Insertion tool is used to first evacuate the unit and then insert the CoreMax valve when evacuation is complete. A SnapMate connector or a charge gun connector is then used at the charging station.
- Higher flow improves vacuum quality to maximize SEER rating
- Shortest evacuation time for:
- FasTest line throughput
- Fewer evacuation stations freeing up floor space
Improved Field Service
The CoreMax System is compatible with commonly used service connectors and caps. The CoreMax valve uses the same thread, taper and sealing surface as standard refrigeration access valves. Service technicians do not need to buy special tools, but with evacuation rates as fast as most 1/4” process tubes and connectors they will want to.
Using the SnapMate Service connector with the CoreMax high-flow access valve allows field evacuation rates to be as fast as production rates, dramatically reducing service.
Schrader style access valves have two leak paths and poor tolerance control making them prone to leaks. They have a sleeve seal between the valve core and the seat and an additional elastomer seal on the valve. The CoreMax valve core uses one elastomer to seal both the valve and the seat and also has a metal to metal seal for redundancy on the seat. The valve core pin positioning is manufactured to exacting tolerances for consistent sealing and valve opening. For use with existing service tools and caps, it has the same (7/16-20) thread, taper and sealing surface as commonly used on refrigeration valves (ANSI/ARI standard 720-2002).

Valve Core - Installation Instructions
JB Industries and FasTest have partnered to offer the CoreMax family of manufacturing and service tools. This integrated, flexible system shortens processing time and provides up to five times greater processing flow, dramatically improving sealing with faster access connections. Unlike other systems, CoreMax is an integrated system design, not just a component design. The revolutionary CoreMax System allows processing through the seat or the valve, and is centered around the high flow CoreMax access valve. Common access valves have a sleeve seal between the valve core and the fitting with an elastomer seal on the valve, creating two leak paths. CoreMax uses only one elastomer to seal the valve internally and externally through the valve core and seat; a metal-to-metal seal is also provided between the valve core and seat.
