Filling Valve for Compressor Air Tank 1/4 NPT Extended Schrader Valve with Knurled Head Chrome-Plated Metal Silver Workshop
You already have the maximum available quantity in your cart.
The extended filling valve with a bottom thread 1/4 NPT is designed for filling and emptying air in compressor air tanks and other pressure vessels. The stronger tapered thread screws into the opening of the vessel, and above the hexagon, a tall stem with a knurled head protrudes. This design allows easy access even in vessels with surrounding components or welds. The metal body features a silver chrome-plated finish with a shiny appearance. This part is appreciated by auto repair shops, DIY enthusiasts, and owners of smaller compressors who are upgrading or repairing their own air storage tanks.
The valve uses a Schrader valve, the same type found in car tyres. Therefore, you can fill the vessel with the same inflation nozzle from the compressor that you use for your tyres, and it is equally easy to connect a pressure gauge to check the pressure. Upon disconnecting the nozzle, the valve automatically seals the outlet, keeping the air inside. When it is necessary to empty the vessel, simply press the valve needle.
The taller stem raises the valve above the surface of the vessel, making it convenient to attach the nozzle without your hand hitting surrounding components. The knurled head improves grip during handling with fingers, and the hexagon allows for secure tightening with a standard wrench. The valve is suitable for workshop compressors, portable inflation tanks in the garage and on the road, and for home constructions from pressure vessels. The stronger 1/4 NPT thread fits larger openings found in many air tanks, and the extended stem also allows for nozzle attachment even when the valve is positioned deeper among other components.

Before installation, we recommend wrapping the NPT thread with Teflon tape or using a suitable thread sealant to ensure a good seal. Screw the valve into a non-pressurised vessel and tighten it with a wrench on the hexagon, never on the upper stem. After filling with air, check the tightness of the connection by applying soapy water. If bubbles appear, tighten the valve or re-seal the thread. Keep the metal surface clean by wiping it with a dry cloth.
The extended filling valve is a practical part for anyone working with compressed air. The bottom thread 1/4 NPT securely connects it to the vessel, and the upper valve connects to the compressor or pressure gauge. The tall stem makes attaching the nozzle easier, and the hexagon ensures a firm tightening. It serves as a replacement part for older air tanks and for building portable pressure vessels. Thanks to the silver chrome-plated surface, it looks clean and fits well into any workshop.
