Description
The 1/4″ Female Flare (FFL) Hex Cap is a essential draught component for sealing off unused 1/4″ Male Flare (MFL) ports on manifolds, regulators, or ball lock disconnects. Constructed from high-purity solid brass, it provides a high-pressure, leak-proof seal that is far more durable than plastic alternatives. This model features a specialized internal washer to ensure a 100% airtight seal. The hex-nut profile allows for secure tightening with a standard wrench, making it the professional choice for long-term system maintenance.
Technician’s Note: Always ensure the included washer is present and seated correctly before threading the cap onto an MFL fitting. Hand-tighten until snug, then use a wrench for a final 1/4 turn. These caps are indispensable for isolating parts of a draught system during leak testing or when a gas line is being removed for extended periods.
