The CAV-110H-4 is a push-type aircraft fuel drain valve used in general aviation fuel systems for safe and controlled fuel sampling. It is designed to mount into fuel sumps, gascolators, and drain points, allowing pilots and maintenance personnel to quickly check for water or contamination in fuel.

This model uses a simple spring-loaded push mechanism with an O-ring sealing system that prevents leaks and reduces clogging caused by dirt or debris. It is FAA/PMA approved and widely used across light aircraft fuel systems.

Key features include:

Push-to-open fuel sampling valve
1/8"-27 NPT threaded aircraft installation
FAA/PMA approved aviation component
Brass/steel construction depending on variant
O-ring sealed stem design for leak prevention
Rebuildable maintenance-friendly design
60 PSI max operating pressure rating
Used in fuel sumps and gascolator drain points
Resistant to vibration and temperature extremes
Designed for quick pre-flight fuel contamination checks
Common in Cessna, Piper, Mooney, and similar GA aircraft installations
