Push-in plugs provide a quick and convenient way to block off unused ports in pneumatic systems. Their simple push-fit design allows fast installation and removal without tools, creating a reliable, leak-free seal whenever a line connection point needs to be temporarily or permanently closed. These fittings are designed for compressed air only (not water or other gases), with a working pressure of 0–150 psi (10.3 bar) and a temperature range of 0 °C to 60 °C. Ideal for workshops, industrial plants, and OEM applications where unused ports must be safely sealed. We can supply the full range and usually deliver quickly – please contact us if you need sizes not listed.
