Probably not this valve's intended use ...but it does the job perfectly ### ⭐⭐⭐⭐⭐ Perfect fit. *by E***K on July 6, 2024* Fits perfect with steam whistles. Perfect for model engines,etc. ### ⭐⭐⭐⭐⭐ Works perfectly! *by L***Y on January 24, 2021* You can see the valve in the photo in the footwell of my car, the good news is you can loosen the brass nut on top of the valve and turn the valve lever to any direction you want. That helps a lot. The valve works, the threaded holes are 3/8 npt, I used adapters to make them quarter inch, and I took the lever off and put an angle bracket on there to hold it, it is difficult to see in the photo, but there are two screws going through the carpet into the firewall to hold the valve in place. ## Frequently Bought Together - Kingston 305A Series Brass Quick Opening Flow Control Valve, Pull Lever, 3/8" NPT Female - Threaded Base Steam Train Whistle 5 Chime Aluminum - Primefit R3802G Intermediate Air Regulator with Steel-Protected Gauge at 100-PSI, 3/8-Inch NPT --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.sa/products/62672706-kingston-305a-series-brass-quick-opening-flow-control-valve-pull](https://www.desertcart.com.sa/products/62672706-kingston-305a-series-brass-quick-opening-flow-control-valve-pull) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-05-28*
