The High-Flow Tool That Connects to a CoreMax® Valve at Every Station

The FasTest CoreMax® SnapMate OEM Tool is a high-flow, push-to-connect processing tool that connects to a CoreMax® valve for evacuation, charging, testing, and rework. It is built for OEM production lines — the intent is that one tool is used at every station a unit passes through, from a single connection type, at speeds from 10 millitorr of vacuum up to 750 psi (51.7 bar).

The point of the tool is inseparable from the valve it connects to. The CoreMax® valve is FasTest’s high-flow refrigerant access valve, and its advantage — faster evacuation and charging than a conventional access port — is only realised if the tool connecting to it does not become the restriction. The SnapMate delivers matched flow through the CoreMax® valve, so the high-flow path is carried through the tool rather than choked at it. On a line where evacuation time is often the cycle-time bottleneck, that is the difference between having a high-flow valve and actually processing at high flow.

Two features make it fit high-volume production. It is actuated under full pressure: a mechanical-advantage design lets an operator make and break the connection while the system is under vacuum or at pressure, so there is no depressurising step before connecting. And it grips behind the threads rather than on them, which eliminates the thread damage that repeated threaded connections inflict — important because the CoreMax® valve stays on the finished product and may be accessed again in the field.

For the operator, the SnapMate replaces repetitive twisting with an easy push-to-connect, pull-to-release sleeve action. Across thousands of connections a shift that is an ergonomic difference as much as a speed one. And because the internal valve opens automatically on connection and closes on disconnection, flow is controlled by the act of connecting — the connection is live only while the tool is on, and closed the moment it comes off.

The Problem the FasTest CoreMax® SnapMate OEM Tool Solves

Connecting to a refrigerant access valve, thousands of times a shift, across every station on a production line, raises problems a threaded hose connection does not answer:

• A restrictive tool wastes a high-flow valve: Evacuation and charging time depends on the whole flow path. Put a restrictive connection on a high-flow valve and the tool becomes the bottleneck, giving back the cycle time the valve was chosen to save.
• Threaded connections are slow and tiring: Screwing a connection on and off at every station means repetitive twisting — slow per unit and hard on operators over a full shift of high-volume work.
• Threads wear with repeated connection: A tool that engages the valve threads on every cycle gradually damages them — on a valve that stays on the product and may be serviced later, that is the customer’s problem down the line.
• Depressurising to connect costs time: If the tool cannot be connected under pressure, every connection or disconnection adds a pressure-management step.
• An open port loses refrigerant: A connection that does not close itself on disconnection risks releasing refrigerant into the workspace each time the tool comes off.

The FasTest CoreMax® SnapMate OEM Tool answers each: matched high flow keeps the tool from restricting the valve, a push-to-connect sleeve replaces twisting, gripping behind the threads eliminates thread damage, the mechanical-advantage design allows connection under full pressure, and the internal valve closes automatically on disconnection.

Key Features 

Matched High Flow Through the CoreMax® Valve

The SnapMate OEM Tool carries matched flow through the CoreMax® valve, so the tool does not restrict the high-flow path the valve provides. This is the feature that makes the CoreMax® system worth adopting: the valve’s faster evacuation and charging only reach the process if the tool connecting to it flows just as freely. Matched flow is what turns a high-flow valve into high-flow processing.

Internal Valve Opens on Connection, Closes on Disconnection

An internal valve opens automatically when the tool connects and closes when it disconnects, so flow is enabled only while the tool is engaged. The operator does not open or close anything separately — the connection itself controls the flow path — and because it closes on disconnection, the port is not left open to lose refrigerant or draw contamination when the tool comes off.

Actuated Under Full Pressure

A mechanical-advantage design lets the SnapMate be connected and disconnected under full pressure, in both vacuum and pressure applications, across its full range to 750 psi (51.7 bar). There is no need to bring the system to a neutral pressure before making or breaking the connection, which removes a step from every cycle and suits the reality of a line where units are already under vacuum or charge.

Grips Behind the Threads — No Thread Damage

Rather than engaging the valve threads, the SnapMate grips behind them. Over thousands of production connections that eliminates the thread wear a threaded tool would cause — which matters because the CoreMax® valve remains on the finished unit and may be accessed again in service. Preserving the threads in production protects a connection the end customer may rely on later.

Ergonomic Push-to-Connect Sleeve

The sleeve action is push-to-connect, pull-to-release — no twisting or turning. At production volumes the ergonomic benefit is real: an operator making hundreds or thousands of connections a shift is spared the repetitive wrist motion of a threaded connection, and each connection is faster and more consistent for it.

Technical Specifications

Where the FasTest CoreMax® SnapMate OEM Tool Is Used

Evacuation

Before charging, a refrigerant system is evacuated to remove air and moisture. This is where high flow matters most: evacuation time is often the cycle-time bottleneck on a line, and matched flow through the CoreMax® valve, down to 10 millitorr, is what lets the SnapMate pull that vacuum quickly rather than being throttled at the tool.

Charging

The same tool charges the system with refrigerant. Matched high flow speeds the charge, the connection is made under pressure without a separate step, and the internal valve closes on disconnection so the charge is contained the moment the tool comes off.

Burst and Leak Testing

At test stations the SnapMate connects to the CoreMax® valve for burst and leak testing across its range to 750 psi (51.7 bar). Connecting under full pressure and gripping behind the threads means the test connection is fast and does not wear the valve over repeated cycles.

Rework

When a unit needs to be re-accessed — to recover, recharge, or correct — the SnapMate reconnects to the same CoreMax® valve. Because production connections never damaged the threads, the rework connection is as clean as the first, and the push-to-connect action makes re-access quick.

Frequently Asked Questions

Q: What is the CoreMax SnapMate OEM Tool?

A: It is a FasTest high-flow OEM processing tool that connects to a CoreMax® valve for evacuation, charging, testing, and rework, from 10 millitorr of vacuum to 750 psi (51.7 bar). It is designed to be used at every station on a production line, with a push-to-connect sleeve action.

Q: What does the SnapMate OEM Tool connect to?

A: A CoreMax® valve — FasTest’s high-flow refrigerant access valve. The tool grips behind the valve’s threads and carries matched flow through the valve for efficient processing.

Q: What does “high flow” or “matched flow” mean here?

A: The CoreMax® valve flows faster than a conventional access port, which speeds evacuation and charging. “Matched flow” means the SnapMate’s own flow path is sized to match the valve, so the tool does not become the restriction — the high-flow benefit is carried through the connection rather than lost at it.

Q: Can the SnapMate OEM Tool be connected under pressure?

A: Yes. Its mechanical-advantage design lets it be connected and disconnected under full pressure, in both vacuum and pressure applications, across its full range to 750 psi (51.7 bar) — so there is no depressurising step before connecting.

Q: Does the SnapMate damage the CoreMax valve threads?

A: No. It grips behind the threads rather than engaging them, which eliminates the thread wear a threaded tool would cause over repeated production connections. That matters because the CoreMax® valve stays on the finished product and may be accessed again in service.

Q: What happens to refrigerant when the tool disconnects?

A: The internal valve closes automatically on disconnection, so the port is not left open. Flow is enabled only while the tool is connected, which keeps the refrigerant contained when the tool comes off.

Q: What is the difference between the SnapMate OEM Tool and the SnapMate Service Tool?

A: The OEM Tool is built for production lines — used at every station for generalized processing, connecting to CoreMax® valves, rated to 750 psi (51.7 bar). The Service Tool is for field service and connects to both CoreMax® and Schrader® flare connections, rated up to 625 psi. Choose the OEM Tool for the factory and the Service Tool for field access; contact FasTest to confirm the right one for your use.

Q: Is the SnapMate a quick-connect coupling?

A: It is a reusable processing tool rather than a permanent coupling. It makes a fast push-to-connect sleeve connection to a CoreMax® valve for processing, then releases — so if you are looking for a quick, repeatable way to connect to CoreMax® valves at production stations, that is what it does, but it is tooling, not a fitting that stays on the product.

Q: What stations is the SnapMate OEM Tool used at?

A: Burst, evacuation, charge, and rework stations — the design intent is one tool used at every station a unit passes through, all connecting to the same CoreMax® valve.

Q: What industries use the SnapMate OEM Tool?

A: HVAC-R and refrigerant systems manufacturing in particular — air conditioning, refrigeration, and heat pump production — along with appliance and automotive AC lines that use CoreMax® high-flow refrigerant access valves.
