Standards Leadership
Parafour's founder has been instrumental in shaping ASME, NFPA, and NTEP standards for LPG dispensing — giving our customers equipment designed by the people who set the bar.
"When you build equipment to standards you helped develop, you understand exactly where the margins are — and why they exist. Every Parafour dispenser reflects that depth of knowledge: not just compliant, but built the way the standard intended."— Parafour Innovations, LLC
