World American WA289714 Quick Release Valve QR1C
The WA289714 is a QR-1C quick-release valve designed for heavy-duty air brake systems. It features a 0 PSI differential with a 0.375-inch delivery port, enabling fast brake release in commercial vehicles. The valve uses a precision port layout: supply port 0.25 inch, delivery port 0.375 inch, and balance port 0.25 inch, with NPT threading for secure, leak-free connections. This valve is best for fleets prioritizing rapid brake release in urban deliveries or long-haul applications where quick tank venting improves stopping response. Caution: verify port dimensions on your current setup to ensure proper fitment and avoid cross-threading during installation.
Who it’s best for: Operators needing reliable, fast brake release where space is limited and standard ports match 0.25″ supply and 0.25″ balance lines.
Why selected: Compact height (2.68 inches) and NPT ports provide durable performance in harsh environments while fitting into constrained spaces.
Limitations: As with any valve, incorrect port matching can lead to improper function; confirm compatibility with your vehicle’s braking system before purchasing.
