The Problem We Solve
ICD 705 Requires an Electrical Break. There Was No Commercial Solution.
Intelligence Community Directive 705 requires all metallic lines, including refrigerant lines, crossing a SCIF perimeter to include an electrical break. Without it, copper refrigerant lines create a direct security vulnerability.
EKFox Gear manufactures the only purpose-built HVAC components designed specifically for this requirement, the non-conductive refrigerant line break. Pressure-rated, UL tested, and available in 8 sizes from Chantilly, VA.

Applications
Wherever a metallic refrigerant line must cross a shielded boundary or security partition, an ICD 705 compliant HVAC solution is required . EKFox Gear’s non-conductive break is the HVAC solution engineers and contractors specify for shielded enclosure HVAC and SCIF installations.
Split AC systems
For SCIFs requiring electrical isolation at the secure wall.
Split heat pumps
Dielectric break on liquid and suction refrigerant lines per ICD 705.
Shielded enclosures
Prevents signal propagation through metallic pipe.
ICD 705 compliant spaces
Installs at the security partition interior per UFC 4-010-05 requirements.
High-security areas
Government, DoD, and intelligence community installations.
Features & Benefits
Engineered for refrigerant service in secure environments. Purpose-built HVAC components built to a specification no standard fitting could meet.
Compatible with R-410A & POE oil | A2L UL testing in progress
Rated for high-pressure R-410A and POE oil systems. Formal A2L certification with UL Solutions in progress - completion Q2 2026.
Compact size and easy installation
Designed for straightforward installation using no-brazed methods, such as press-to-connect or push-to connect fittings. Compatible with standard HVAC brazing methods as long as the ACR copper tubing remains unshortened.
100% electrical isolation of components
Complete dielectric break in the metallic refrigerant line, eliminates electrical continuity across the secure boundary as required for SCIF HVAC compliance.
About EKFoxGear
EKFox Gear is a specialized division of E.K. Fox & Associates focused on developing purpose-built products for complex facility challenges where standard solutions do not exist.
Founded in 2018 and headquartered in Chantilly, Virginia, EKFox Gear combines engineering expertise with prototyping, testing, and fabrication capabilities to develop practical solutions for commercial, government, and high-security facilities.
Our product-focused approach grew from real project needs, including specialized requirements for SCIFs, secure facilities, and other demanding environments. From concept and testing through fabrication, EKFox Gear develops solutions for applications that conventional products cannot address.
Industries We Serve
Our SCIF HVAC components are specified by government contractors, MEP engineers, and HVAC installers across four sectors.
Commercial
Corporate SCIFs, financial trading floors, and high-security commercial facilities require the same isolation standards as government installations.
Government
Federal, DoD, and intelligence community facilities specifying dielectric breaks per DHS SCIF standards and ICD 705.
Data Centers
Secure data centres require electrical isolation of refrigerant lines where they cross shielded zones or security boundaries.
SCIF
Sensitive Compartmented Information Facilities require a dielectric break on all metallic lines crossing the secure perimeter - per ICD 705.
