Push-in caps provide a fast and effective way to seal the end of a tube in pneumatic systems. With a simple push-fit design, they allow quick installation and removal without tools, ensuring a secure closure when a line is not in use or needs isolating. Suitable for compressed air only (not water or other gases), these caps are rated for 0–150 psi (10.3 bar) and operate within a temperature range of 0 °C to 60 °C. Ideal for workshops, industrial plants, and OEM use where lines require temporary or permanent sealing. We can supply the full range and usually deliver quickly – please contact us if you need sizes not listed.
