One Field Connector for CoreMax® and Schrader® Alike
The FasTest CoreMax® SnapMate Service Tool is the field-service connector of the CoreMax® family — the counterpart to the SnapMate OEM Tool that runs on the production line. Where the OEM tool is built for CoreMax® valves on the line, the Service Tool is built for the field, and its defining feature is that it connects to both CoreMax® valves and common Schrader® / 45° flare fittings.
That dual compatibility is what makes it a field tool. A technician in the field meets both kinds of connection: CoreMax® high-flow valves on newer equipment, and standard Schrader® valves and 45° flare fittings across the large installed base of existing systems. A connector that instantly locks onto either means one tool covers the whole service call rather than a CoreMax® tool in one hand and a Schrader® fitting in the other. The collet design locks securely into CoreMax® and common Schrader® valves alike.
It is built for the field in two more ways. It makes instant connections — a fast, secure collet lock rather than a threaded fitting — so a tech connects and moves on. And it is internally valved for refrigerant containment on disconnection: when the tool comes off, its internal valve contains the refrigerant rather than venting it, which matters both for the environment and for not losing charge on every disconnect. Through that connection the tool evacuates and charges refrigerant during field servicing.
The Service Tool is rated for vacuum to 625 psi (43 bar) — the field-service rating, appropriate to CoreMax® and Schrader® / flare work (the CoreMax® production tools and seats run to 750 psi). It handles 45° flare, CoreMax®, and Schrader® connections through the one collet head, actuated by a sleeve.
The Problem the FasTest CoreMax® SnapMate Service Tool Solves
Servicing refrigerant systems in the field, across old and new equipment, creates problems the Service Tool is built to remove:
-
Two connection types in the field: New equipment has CoreMax® valves; the installed base has Schrader® valves and 45° flare fittings. One connector that locks onto both means one tool for the whole call, not two.
-
Threaded connections are slow: Threading a hose onto a Schrader® port is slow and fiddly. An instant collet lock connects and releases quickly, which adds up over a day of service calls.
-
Disconnecting shouldn’t vent refrigerant: Pulling a tool off a charged system without containment releases refrigerant. The internal valve contains it on disconnect — better for the environment and for the charge.
-
Field work needs a secure lock: A connection that could slip under pressure is a hazard. The collet locks securely into the valve, on CoreMax® and Schrader® alike.
The FasTest CoreMax® SnapMate Service Tool answers each: dual CoreMax® and Schrader® / flare compatibility, an instant secure collet connection, internal-valve refrigerant containment on disconnect, and field evacuation and charging through one connector.
Key Features
Connects to Both CoreMax® and Schrader® / 45° Flare
The Service Tool makes instant connections to CoreMax® valves and to common Schrader® and 45° flare fittings. That is its central advantage as a field tool: it bridges the CoreMax® system and the large installed base of standard fittings, so one connector covers whatever a technician finds on site — new CoreMax®-equipped systems and existing Schrader® / flare systems alike.
Collet Design Locks Securely
A collet design locks the tool securely into CoreMax® and common Schrader® valves. The collet is what lets one head grip both connection types and hold under pressure, so the connection is fast to make and stays put during service.
Internally Valved — Refrigerant Containment on Disconnect
The tool is internally valved for refrigerant containment upon disconnection: when it comes off, the internal valve contains the refrigerant rather than venting it to atmosphere. For field service that is both an environmental and a practical benefit — refrigerant is not lost, and disconnection is clean.
Instant Connections — Fast Field Work
Instant collet connections replace the slow thread-on of a conventional fitting, so a technician connects, works, and moves to the next unit quickly. Over a day of calls, connection speed is real time saved.
Evacuate and Charge in the Field, to 625 psi
Through the one connection the tool evacuates and charges refrigerant during field servicing, rated from vacuum to 625 psi (43 bar). That covers the field-service range on both CoreMax® and Schrader® / flare connections.

Where the FasTest CoreMax® SnapMate Service Tool Is Used
Field Service of CoreMax®-Equipped Systems
On systems built with CoreMax® high-flow access valves, the Service Tool is the field connector — instant collet connection to the CoreMax® valve for evacuation, charging, and related service, with refrigerant contained on disconnect.
Service of Schrader® / Flare Systems
On the large installed base of equipment using Schrader® valves and 45° flare fittings, the same tool connects and services those too — so a technician does not need a separate connector for older systems.
Field Evacuation and Charging
The tool’s core field job is to evacuate and charge refrigerant during service, to 625 psi, through whichever connection the equipment presents.
HVAC-R Service and Maintenance
Its home is HVAC-R service — air conditioning, refrigeration, and heat pump maintenance in the field — where a single connector for CoreMax® and Schrader® / flare, with refrigerant containment, suits the realities of a service call.

Frequently Asked Questions
Q: What is the CoreMax SnapMate Service Tool?
A: It is the field-service connector of the CoreMax® family — a tool that makes instant, leak-tight connections to both CoreMax® valves and common Schrader® / 45° flare fittings for field evacuation and charging, up to 625 psi, with an internal valve that contains refrigerant on disconnect.
Q: Does it work with both CoreMax and Schrader fittings?
A: Yes — that is its defining feature. A collet head locks securely into CoreMax® valves and common Schrader® valves, and it also connects to 45° flare fittings. One tool covers new CoreMax®-equipped systems and the installed base of standard fittings.
Q: What is the difference between the SnapMate Service Tool and the SnapMate OEM Tool?
A: The OEM Tool is the production-line tool for CoreMax® valves — high-flow processing at every station. The Service Tool is the field tool: it adds Schrader® and 45° flare compatibility for the installed base, uses an instant collet connection, and contains refrigerant on disconnect. Use the OEM tool on the line and the Service Tool in the field.
Q: What does the collet design do?
A: It locks the tool securely into the valve — CoreMax® or common Schrader® — with an instant connection, so one head grips both connection types and holds under pressure without threading.
Q: Does the tool release refrigerant when disconnected?
A: No — it is internally valved for refrigerant containment on disconnection. When the tool comes off, the internal valve contains the refrigerant rather than venting it to atmosphere, which protects both the environment and the system charge.
Q: What pressure is the Service Tool rated for?
A: Vacuum to 625 psi (43 bar) — the field-service rating. (The CoreMax® OEM production tools and the seats are rated to 750 psi.)
Q: Is it a quick connect?
A: It is a reusable quick-connecting service tool: it makes an instant collet connection to a CoreMax®, Schrader®, or 45° flare fitting for service and then releases, containing refrigerant as it does. It is a service connector, not a permanent quick-connect coupling left on the system.
Q: What can I do with it in the field?
A: Evacuate and charge refrigerant, and related service processes, on both CoreMax® and Schrader® / flare systems — all through one connection, with refrigerant contained on disconnect.
Q: What connections does it fit?
A: 45° flare, CoreMax®, and Schrader® connections.
Q: What industries use the CoreMax SnapMate Service Tool?
A: HVAC-R — air conditioning, refrigeration, and heat pump service and maintenance in the field — wherever technicians work across both CoreMax®-equipped and Schrader® / flare-equipped systems.
