Leak Test Connectors
HVAC-R Processing Connectors
Processing tools for HVAC-R system operations: proof testing, evacuation, charging, and recovery. Processing connectors connect to threads, straight and expanded tubes, ISO-B quick connects, plugs, nipples, Schrader valves, and other HVAC-R profiles. Designed for the repeated connect-disconnect cycles of production and field service, with high-flow designs that minimize evacuation and charge times.
Compressed Gas Fill Connectors
No-twist, no-turn cylinder filling connectors for industrial, medical, and specialty gas operations. Available in bail-handle, sleeve-locking, and yoke (MediMate®) configurations for CGA, NF, BS, DIN, and UNI valve standards. Patented safety locking mechanisms prevent accidental separation under pressure. Compatible with nitrogen, oxygen, CO2, air, argon, inert gases, oxidizers, and flammable gases.
Access Ports & Valves (CoreMax®, PortMax™, ZeroMax™)
High-flow, zero-emission access ports that replace traditional Schrader, packed angle, Rotolock, and ball valves on refrigeration and heat pump systems. CoreMax® provides high-flow access for Schrader-type connections. PortMax™ is a full-bore brazed port for maximum flow on large-capacity systems. ZeroMax™ delivers hermetically sealed, zero-emission access. All are compatible with current and next-generation refrigerants.
System Solutions
Complete, engineer-designed packages of sealing connection tools configured for specific applications. System solutions include the EvacMax™ automated evacuation cart for commercial and industrial refrigeration, Engine Test Packages for powertrain leak testing, and custom system configurations for any application requiring matched, validated tooling across multiple connection points.
Custom Engineered Solutions
When standard products don’t fit, FasTest’s custom engineering team designs the solution from scratch. Custom capabilities include modified standard connectors, purpose-built custom connector designs, custom leak test fixtures, and complete custom leak test systems. Thousands of custom projects completed across every industry FasTest serves.
ICON™ Intelligent Connection Technology
FasTest’s process automation platform, available across the product line. ICON™ integrates sensing, SURE SEAL™ seal confirmation, and real-time data output into the connector itself—enabling digital seal verification, step completion confirmation, and PLC integration for automated and semi-automated test stations.
Maintenance Parts
Replacement seal kits, wear parts, and maintenance components for FasTest connectors and tools. Keep your production running with readily available maintenance parts shipped from FasTest inventory. Many parts ship within 48 hours.
Three Ways to Find the Right FasTest Product
- Use the Product Filter: The filter tool on this page lets you narrow products by connection type, port geometry, actuation method, industry, and series. If you know what kind of port you’re connecting to, this is the fastest path to finding a matching connector.
- Browse by Category: Use the product category descriptions above to navigate to the right product family. Each category page includes additional filtering and detailed product specifications.
- Submit an Application Evaluation: If you’re not sure which product fits your application, submit an Application Evaluation with your port specifications, test requirements, and drawings. A FasTest engineer will review your application and recommend the right solution—whether that’s a standard product, a modification, or a custom design. There’s no cost and no obligation.
