Trusted Access Solution – DiversiTech MAC In-Line Piercing Valve for HVAC Systems
The DiversiTech MAC In-Line Piercing Valve is designed for fast, secure access to refrigerant lines in HVAC systems, making it a reliable solution for charging, evacuation, or diagnostic work. Built for professionals, this valve delivers durability and precision for copper or aluminum tubing ranging from 1/2" to 5/8" outer diameter.
Engineered for HVAC Service Professionals
This in-line piercing valve allows for efficient access without depressurizing the system or using a torch. It features a winged cap for hand-piercing, a back-seating needle that automatically seals once servicing is complete, and refrigerant-resistant O-rings for a long-lasting, leak-free seal.
Key Performance Features
- Easy Tube Access: Pierces copper or aluminum tubing (1/2"–5/8" OD) without requiring the system to be opened.
- Tool-Free Piercing: Wing cap enables hand-actuated line piercing—no need for extra piercing tools.
- Auto-Seal Needle: Spring-loaded needle retracts after hose removal, sealing the system to prevent leaks.
- Refrigerant Compatibility: Sealing components are designed to withstand exposure to common refrigerants like R-22 and R-134a.
- Simple Installation: Includes hex wrench and two socket-head screws for quick and secure mounting to the line.
Installation Recommendations
Although this valve is built for fast application, proper installation is critical to avoid leaks or line damage. Professional HVAC technicians should handle installation to ensure full compliance with EPA guidelines and local codes. DIY users with refrigerant-handling knowledge should proceed cautiously and adhere strictly to safety instructions.
Designed to Withstand Demanding Service Conditions
The MAC piercing valve is frequently used in field service scenarios where time and access are critical. Its robust construction and self-sealing features reduce the risk of refrigerant loss while improving turnaround time on-site.
