Filling Valve for Pressure Vessel 1/4 NPT Short Schrader Valve with Knurled Head Chrome-Plated Metal Silver For Compressor
You already have the maximum available quantity in your cart.
The short filling valve with a bottom thread 1/4 NPT is designed for air receivers of compressors, portable pressure bottles, and other containers into which compressed air is filled. The robust conical thread screws into the opening in the vessel, and only a low stem with a knurled head protrudes above the hexagon. This means the valve takes up little space and does not obstruct when transporting or storing the vessel. The metal body has a silver chrome-plated finish. The valve is suitable for workshops, garages, and for DIY enthusiasts who repair or assemble their own air tanks.
Inside, it features a Schrader valve of the same type found in car tyres. This allows you to fill the vessel with a standard compressor inflating nozzle and just as easily connect a pressure gauge to check the pressure. After disconnecting the nozzle, the valve automatically seals the exit, keeping the air in the vessel. To release the air, simply press the needle of the valve in the middle of the upper part.
The hexagon in the middle of the body allows the valve to be securely tightened with a standard spanner, while the knurled head improves grip during handling with fingers. The valve is useful for smaller workshop compressors, for portable tanks for inflating tyres, and for home constructions from pressure vessels where air needs to be quickly filled and released. The short design is especially appreciated where there is little space around the vessel opening or where a taller valve could snag and get damaged when transporting the vessel. The robust 1/4 NPT thread also fits larger openings commonly found in air receivers.

Before installation, wrap the NPT thread with Teflon tape or apply suitable thread sealant to ensure a reliable seal. Always screw the valve into the vessel without pressure and tighten it with a spanner on the hexagon. After the first filling, check the tightness of the joint by applying soapy water. If bubbles appear, slightly tighten the valve or reseal the thread. The chrome-plated surface only needs to be wiped occasionally with a dry cloth.
The short filling valve is a simple part for anyone working with compressed air. The bottom thread 1/4 NPT connects it to the vessel, and the upper valve connects to the compressor or pressure gauge. The low profile saves space, and the hexagon ensures a firm tightening. It serves as a spare part for older air receivers or for building a portable pressure bottle. Thanks to the silver chrome-plated finish, it blends well with other metal parts in the workshop.
